JeVois is an ARM Linux based camera module, delivered by JeVois Inc.. So far, this is the ONLY ARM Linux based camera module that I’m recommending, for its well-designed community as well as plenty of source code on Github.

1. Specifications

Clearly:

2. Getting Started with Jevois

The BEST place to start with JeVois is the following Youtube video:

I’m NOT going to repeat this step-by-step setup but move forward to the demonstration step directly.

3. Connect JeVois with Host

After having flashed JeVois’s TF card with the LATEST Linux image, we connect JeVois camera module into the laptop. This TF card will NOT mount onto the computer as a device automatically, but can be detected by lsusb as follows:

4.2 JeVois Inventor

4.2.1 JeVois Tutorial

Again, a Youtube video is suggested to follow for the demonstration:

4.2.2 My Test

You can either download JeVois Inventor directly from the Official Website, or like me, build JeVois Inventor source code from scratch, based on my own QT, etc. Anyway, after JeVois Inventor has been successfully installed, it’s the time for us to test it out.

Being quite busy these days. Seriously, ARM board based on AllWinner H3 from my company Longer Vision is manufactured, and under test. Let’s have some fun.

😀

In the end, better to listen to some music while blogging.

1. Preface

My ESP32-Cam has finally arrived today. The brand of AI Thinker has been demonstrated to be reliable.

In fact, I strictly followed randomnerdtutorials's blog ESP32-CAM Video Streaming and Face Recognition with Arduino IDE to demonstrate this low-cost video surveillance camera. So, in this blog, I ONLY enumerate some KEY POINTS that should be emphasized.

2. Connection

2.1 Schematic

ESP32-Cam can be connected to my laptop exactly the same as shown (cited directly from ESP32-CAM Video Streaming and Face Recognition with Arduino IDE).

2.2 Real Connection

The real connection looks as:

3. Key Points on Flashing ESP32-Cam

3.1 Code Modification

Example code CameraWebServer should be trivially modified as:

//#define CAMERA_MODEL_WROVER_KIT
//#define CAMERA_MODEL_ESP_EYE
//#define CAMERA_MODEL_M5STACK_PSRAM

4. Multiple Camera Streaming with Static IPs

I’m NOT going to talk about how to set up static IPs for IP cameras (well, yes, clearly, ESP32-Cam can be looked on as a low-cost video surveillance IP camera for sure). We ONLY demonstrate 4 ESP32-Cams are under streaming simultaneously with 4 statically allocated IP addresses.

We show the capturing effects FIRST:

Four ESP32-Cams Capturing

Then, we show how the cables are connected by using a power bank and an extra bread board. Here, FTDI is just used as a power adaptor to provide 5V voltage.

噩耗传来，今晨，高中同学逝世，年仅43岁。今天是2019年8月15日，是日军投降的日子。同学经历4个月急性胰腺炎的煎熬，耗光所有家财，于北京时间早上9时11分不治。这两个神奇的时间...

难忘高中一起踢球、打麻将的日子。在球场上，他是跑不死的。而且身体肌肉比较多，所以才有两个外号：“施瓦辛格”、“周扎实”。

我的印象，他应该是我们高中班第一位走的同学。人生无常，想当年，他也是我们班第一位获得保送的同学吧？老天爷就是这样不公平。1995年，湖北省是高考前先保送，但是保送了之后还要参加高考，保送者确定必须过一本线才能进入所保送的大学就读。他心态好的出奇，保送东北大学之后就不再学习了，每天看金庸小说。高考竟然考到652？不太记得分数。总之，是一个在湖北省稳稳上清华的分数。经历了本硕连读，东大阿派的锤炼，他成功完成香港中文大学博士学位，并令人羡慕的进入珠海某大学就职，面朝大海、春暖花开的海景房，曾经令我幻想羡慕不已...可惜至今，我也没有机会去看过。

他的婚礼是在武汉办的，我是亲自参加的，他娶了一位非常漂亮的嫂子。他在婚礼上非常紧张，大概是兴奋的？夫妻对拜的时候，竟然说出“感谢娶我为妻”！这个证据确凿，每每想起，忍俊不止。

我在英国的时候，他给我介绍了一个很漂亮的女朋友。可惜缘分没有让我们走到一起。我还是通过这位已经是两个孩子的妈妈，获悉同学的病情，并立即通知高中同班同学筹款。只可惜还是...听到病危病重，真的是不敢相信自己的耳朵！确定水滴筹的照片就是他本人，已经瘦得不成人形！获悉同学病情的前三天，每天早上起床，眼睛湿润都不自知...前几年我到珠海，我们几位高中同学还吃海鲜聚会，没有见到他。没想到那次错过，就错过了一世...

这几年，见得太多了！这个社会，好像真的是：越是好人，越走得早？老天爷啊...“逢庙必拜、遇观必香”...人到中年，真的开始有点相信神佛...根本还没来得及小小欢庆几小时前首次带父母到美国小游，就...明天去列治文拜佛祈福。

我很喜欢卡拉OK，一直想要在hexo blog 加入自己原唱作为背景音乐（这也算是创新吧？），今天这篇不算是祷文的blog，纪念我同学，也算督促我完成了这个小小任务。回到家、刚刚开始check wechat，就看到这个噩耗，真的是... 这是我第一次发全民K歌，中间有跑调，我觉得没有必要修改任何！因为这就是我自己原唱，在听到消息之后，也着实情绪不能控制...

人生的意义在什么？“且行且珍惜”！珍惜身边拥有的一切吧！想起去年某台姐对我说：“看到你一家三口团聚，就感觉很幸福”。是啊...台姐本人从小姥姥带大、10岁出头一个人给姥姥送葬；而周伯伯白发人送黑发人，这...人，真的不能太“不知足”！我思想还没成熟呢！这么大了，怎么长的？太幼稚！！种地，有什么不好？？

不知不觉，温哥华当地时间2019年8月15日凌晨3点20分。愿你在天堂没有痛苦...

Having been keeping an eye on Widora and Espressif for quite a bit. I finally decided to test out Widora's development board AIRV.

1. Background Knowledge

1.1 Espressif

Espressif is based in Shanghai, China, focusing on Wifi/Bluetooth chips, now have two main Wifi modules: * ESP32: Wifi with Bluetooth * ESP8266/ESP8285: Wifi ONLY

1.2 Widora

Widora is headquartered in Beijing, China, providing development boards using Espressif Wifi/Bluetooth chips.

1.3 Kendryte

NEVER heard of Kendryte before. It seems Kendryte develops some AI based on Risc-V chip architecture? That seems to be a good concept...

1.4 HiFive

As for Risc-V, HiFive developed by SiFive has to be mentioned in any case.

For me, a NOBODY has NOT had any chance or capability to deal with chips... So... shame... Anyway, let's test it out... ^_^

2. Test on Widora AIRV Face Detection

By using a RUBBISH USB cable, you should already be able to run the face detection sample code existing inside the board.

Normal Occlusion

However, you really need to use a QUALIFIED Micro-B USB to USB Type A cable, in order to list the device out by lsusb.

4. Reflash Widora AIRV

Today, I got a very BAD news: one of my BEST classmates in my senior middle school has been staying in the hospital for OVER 3 months. The very serious pancreatitis has used up ALL his family's savings. That is the current Chinese medical system. Chinese people have NO 2nd choice: * either be the ruled class, who need to pay unaffordable medical service fee * or be the ruling class, who have THE RIGHT to enjoy ALL types of FREE medical service

SiFive is a NEW birth in the CHIP industry, which is based on RISC-V, started by University of California, Berkeley. I don't know where it will go, and how well it can do. But, innovation is just the right way to breakthrough the STALE ruling class.

1. Zephyr

There are plenty of popular RTOSes for MCUs with different architectures, including ARM, RISC-V, etc.

In my personal point of view: * MCUs: are based on microcontrollers, which are normally single user single thread. * SBCs: come with a true multi-user multi-threading operating system, for instance, Linux.

A detailed summary can be found on Wikipedia.

1.2 Getting Started With Zephyr

Over 150 boards are NOW supported by Zephyr, including today's leading role: HiFive1 Rev B. Let's just test out Zephyr right away.

In the following, we strictly follow Zephyr Getting Started Guide, with trivial customization.

1.2.1 Get the source code

Make sure west has been installed by pip install -U west --user, and then initialize and update Zephyr project contents as:

Step 3: Set Up Toolchain For RISC-V

Using Zephyr's own toolchain is strongly recommended for Zephyr projects (refer to Zephyr Project's Official Documentation ).

1.2.4 Build and Run an Application

Before building and run an application, please make sure you have all required tools ALREADY installed on the host computer. On my HOST Ubuntu 19.04, I've got to manually install dtc (the latest release is version 1.5.0). I'm NOT going to talk about how go figure out installing any REQUIRED packages at this moment. Supposing you've got ALL REQUIRED tools successfully installed ALREADY.

In my case, it's because DTC is wrongly and automatically set to:

even if

dtc: /usr/bin/dtc
➜  zephyr git:(master) ✗ dtc --version
Version: DTC 1.5.0-gb8d6eca7-dirty

Solution 1: Temporary Solution

Reset DTC to value /usr/bin/dtc in file build/CMakeCache.txt

Solution 2: Permanent Solution

Modify file ./cmake/toolchain/zephyr/0.10.1/host-tools.cmake as follows

It seems the messages are from bootloader, sometimes it fails to initialize ESP32 module.

Today I'd love to talk about Pixy Cam a bit, which I do NOT recommend at all. There are several reasons: * Price: As you can see from Amazon, it's comparatively expensive, $95 USD. * Warranty period: 90 days from date of purchase * Size: too big

Actually, I purchased PIXY (with pan tilt mount base) in 2016 from amazon.com. However, it went died long time ago. What's more, I've tested ALL possible solutions from Pixycam Troubleshooting, but the 90-day warranty is easy to pass.

I do NOT want to talk more about Pixy Cam, and here is **my conclusion: Please use esp32-cam instead.

Posted on Edited on In ,

It's almost July 10, let me continue testing something else: OpenMV. I used to have purchased 2 OpenMV cameras, respectively: * OpenMV Cam M4 V2 with STM32F427VG * OpenMV Cam M7 with STM32F765VI

No matter which version of OpenMV is connected to the laptop via USB, command lsusb is able to list the device out as:

Bus 001 Device 020: ID 1209:abd1 InterBiometrics

Dilemma of OpenMV-IDE

Conclusion FIRST: NEVER build OpenMV-IDE from scratch using a different version of Qt!!!

To build OpenMV-IDE is seriously headache.

# Face Detection Example
#
# This example shows off the built-in face detection feature of the OpenMV Cam.
#
# Face detection works by using the Haar Cascade feature detector on an image. A
# Haar Cascade is a series of simple area contrasts checks. For the built-in
# frontalface detector there are 25 stages of checks with each stage having
# hundreds of checks a piece. Haar Cascades run fast because later stages are
# only evaluated if previous stages pass. Additionally, your OpenMV Cam uses
# a data structure called the integral image to quickly execute each area
# contrast check in constant time (the reason for feature detection being
# grayscale only is because of the space requirment for the integral image).

import sensor, time, image

# Reset sensor
sensor.reset()

# Sensor settings
sensor.set_contrast(1)
sensor.set_gainceiling(16)
# HQVGA and GRAYSCALE are the best for face tracking.
sensor.set_framesize(sensor.HQVGA)
sensor.set_pixformat(sensor.GRAYSCALE)

# Load Haar Cascade
# By default this will use all stages, lower satges is faster but less accurate.
face_cascade = image.HaarCascade("frontalface", stages=25)
print(face_cascade)

# FPS clock
clock = time.clock()

while (True):
    clock.tick()

    # Capture snapshot
    img = sensor.snapshot()

    # Find objects.
    # Note: Lower scale factor scales-down the image more and detects smaller objects.
    # Higher threshold results in a higher detection rate, with more false positives.
    objects = img.find_features(face_cascade, threshold=0.75, scale_factor=1.25)

    # Draw objects
    for r in objects:
        img.draw_rectangle(r)

    # Print FPS.
    # Note: Actual FPS is higher, streaming the FB makes it slower.
    print(clock.fps())

# Snapshot Example
#
# Note: You will need an SD card to run this example.
#
# You can use your OpenMV Cam to save image files.

import sensor, image, pyb

RED_LED_PIN = 1
BLUE_LED_PIN = 3

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QVGA) # or sensor.QQVGA (or others)
sensor.skip_frames(time = 2000) # Let new settings take affect.

pyb.LED(RED_LED_PIN).on()
sensor.skip_frames(time = 2000) # Give the user time to get ready.

pyb.LED(RED_LED_PIN).off()
pyb.LED(BLUE_LED_PIN).on()

print("You're on camera!")
sensor.snapshot().save("example.jpg") # or "example.bmp" (or others)

pyb.LED(BLUE_LED_PIN).off()
print("Done! Reset the camera to see the saved image.")

# MJPEG Video Recording Example
#
# Note: You will need an SD card to run this demo.
#
# You can use your OpenMV Cam to record mjpeg files. You can either feed the
# recorder object JPEG frames or RGB565/Grayscale frames. Once you've finished
# recording a Mjpeg file you can use VLC to play it. If you are on Ubuntu then
# the built-in video player will work too.

import sensor, image, time, mjpeg, pyb

RED_LED_PIN = 1
BLUE_LED_PIN = 3

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QVGA) # or sensor.QQVGA (or others)
sensor.skip_frames(time = 2000) # Let new settings take affect.
clock = time.clock() # Tracks FPS.

pyb.LED(RED_LED_PIN).on()
sensor.skip_frames(time = 2000) # Give the user time to get ready.

pyb.LED(RED_LED_PIN).off()
pyb.LED(BLUE_LED_PIN).on()

m = mjpeg.Mjpeg("example.mjpeg")

print("You're on camera!")
for i in range(200):
    clock.tick()
    m.add_frame(sensor.snapshot())
    print(clock.fps())

m.close(clock.fps())
pyb.LED(BLUE_LED_PIN).off()
print("Done! Reset the camera to see the saved recording.")
Video recorded on OpenMV Cam M7

It looks it's NOT easy to demo with the SD card. Please refer to my symptoms on the OpenMV forum.

3. Wifi Module

As expected, OpenMV NOW also privides its Wifi module now. Let's just test the example code from openmv's repo.

# Connect Example
#
# This example shows how to connect your OpenMV Cam with a WiFi shield to the net.

import network

SSID='' # Network SSID
KEY=''  # Network key

# Init wlan module and connect to network
print("Trying to connect... (may take a while)...")

wlan = network.WINC()
wlan.connect(SSID, key=KEY, security=wlan.WPA_PSK)

# We should have a valid IP now via DHCP
print(wlan.ifconfig())

However, it's NOT that handy to have the Wifi module tested.

My conclusion: Please use esp32-cam instead.
