Binocular Stereo Vision Expansion Board for Raspberry Pi

Introduction

This binocular stereo vision expansion board is specially designed for Raspberry Pi Compute Module, compatible with CM3 / CM3 Lite / CM3+ / CM3+ Lite. Small in size but powerful in function. It features three CSI camera ports that can be connected by camera with different viewing angles or baseline value. It is flexible to build different Raspberry Pi stereo vision projects such as binocular parallax ranging, facial recognition, vivo detection, VR video recording and so on. Also, it has some common used ports like DSI and USB, it is convenient to be connected to LCD display and burning mirror directly. Moreover, it has peripheral interfaces like 24PIN HDMI and 36PIN GPIO are also supported through the FPC connector.

Model: RPA20901S

Usager

• 1. Burn image
  

• 1.1 Flash the image to Compute Module 3/Compute Module 3+
  

If you are using Raspberry Pi Compute Module 3 or Compute Module 3+. For these computing modules with eMMC, you need to burn the image to the eMMC on the computing module when using them, otherwise they cannot be used.

The steps to burn to eMMC are as follows:

1) Run RPiboot_Setup software on the computer and install the Raspberry Pi USB driver. It is recommended to turn off the anti-virus software before installation. After the installation is successful, there will be a rpiboot.exe software in the start folder, as shown in the following figure:

2) Switch the USB SLAVE ENABLE switch on the STEREO expansion board to the EN end

3) Connect the computing module (computing module with eMMC)

4) Connect the USB interface on the STEREO expansion board to the PC via a USB cable

5) At this time, open the software rpiboot.exe with administrator authority , and the PC will automatically recognize the eMMC in the computing module as a U disk.

6) Run Win32DiskImager-burn Record the image software , select the image, and burn the image to the eMMC.

Note: If the image has been burned before, you can use the Panasonic_SDFormatter-SD card formatting software to format it before burning.

7) After programming is complete, disconnect the USB cable. After disconnecting the power supply, reconnect the power supply to the PWR interface of the STEREO expansion board to start the system from eMMC.

• Note
  
• During the programming process, the PC should not read and write other USB devices to avoid conflicts;

• The official image provided by Raspberry Pi, the default account is: pi and the password is: Raspberry.

• Since the eMMC of CM3 is only 4G (the latest CM3+ has expanded the capacity of eMMC and can support normal Raspberry Pi mirroring), the size of the burned image cannot exceed 4G. Therefore, if you burn Raspbian, you can only use the Lite version of the mirror. If you want a GUI. You can install the GUI by running the following command after the installation is complete:

sudo apt - get update
sudo apt - get install raspberrypi - ui - mods
