How to use VEYE-MIPI-290/327 camera module on Raspberry Pi

1 Introduction

VEYE-MIPI-290/327 is a is a special camera module which is compatible with RASPBERRY PI. It use SONY STARVIS sensor——IMX290/IMX327 and has excellent ISP functions build-in.The output format is stanard UYVY stream. It is very easy to use it with RASPBERRY PI.Of course, she also has some subtle differences with the official version. She only support 1080p resolution,and i2c cmd is different.

Theoretically,VEYE Camera Modules support all Raspberry Pi. For performance reasons, I recommend you use 3,3+,4 version. This article uses Raspberry Pi 3B as an example to explain how the VEYE-MIPI-290/327 camera module working with Raspberry Pi. It also explain the specials of RPI Computer Module and Zero using VEYE Camera Module.

2 Hardware Setup

Essentials You Need：

• Raspberry PI Items : RPI, Network, MicroSD Card, Power, Monitor
• Camera Module Items : VEYE-MIPI-290/327，FFC，Dupont Wire，Lens，Adaptor Board. （We developed 2 types of adaptor boards, Mini Adaptor Board and Adaptor Board. Mini board only support Standard RPI，Adaptor Board support both Standard RPI and CM & Zero.)

Setup guide

• Connect the VEYE Camera Module the CSI-2 port using FFC Cable（type B).
• Connect Dupont Wire as shown below. VEYE-MIPI-290/327 need an addtional power.
• Startup RaspberryPi.

3 RaspberryPi System Setup and Configuration

• Setup RasapberryPi System，reference this link.
• Go to the main menu and open the Raspberry Pi Configuration tool. Enable Camera and I2C interface.

sudo raspi-config

• Enable SSH and Samba services.
  

4 Sofware Toolkits Install

4.1 Toolkits downloading

There are two way to install software toolkits.

• 1. Clone from github

git clone https://github.com/veyeimaging/raspberrypi.git

• 2. Downloading from github (link here), upload to RPI using samba or USB disk.

4.2 Toolkits Overview

Software Tookits on github

Software toolkits contains three parts. veye_raspcam is raspcam alike Video Stream Toolkits, D_mipi_rpi is D-SDK Video Stream Toolkits, i2c_cmd is Video Control Toolkits.

• Video Stream Tookkits provides real-time display, capture, video recording, etc.
• Video Control Toolkits is a shell script which provides ISP parameters configuration capbility.
• Both is Open Source.
