OV5457 Raspberry Pi Setup Guide

Important: This guide assumes you have a working Raspberry Pi system. If not, please setup your hardware using the tutorial here:

Raspberry Pi Zero Setup Guide (Basic)⁠

These steps are more or less identical for non-Zero Pi models, but you will require a differently sized CSI cable for connecting the camera to

Interfacing with OV-5457 Camera over CSI using Raspberry Pi System-on-Chip

To set up the OV5457 camera with a Raspberry Pi using the CSI hardware interface and the libcamera software interface, follow these steps:

Hardware Requirements:

Raspberry Pi (any version with a CSI interface, which includes all Zero models, the Pi 3, and all modules released afterwards. Note: Raspberry Pi Compute Module models require the development interface for a pre-built CSI interface)

OV5457 camera module

CSI cable (usually provided with the camera module or the Raspberry Pi)

Software Requirements:

Raspberry Pi OS (official OS for Raspberry Pi, preferably the latest version)

libcamera software (comes pre-installed with Raspberry Pi OS or can be installed separately)

Step 1: Connect the Camera Module

Locate the CSI port on your Raspberry Pi, usually near the HDMI ports.

Connect one end of the CSI cable to the CSI port on the Raspberry Pi.

Connect the other end of the CSI cable to the OV5457 camera module. Ensure it's securely connected.

Step 2: Enable the Camera Interface

Boot your Raspberry Pi and open the terminal.

Run sudo raspi-config to open the Raspberry Pi configuration tool.

Navigate to "Interfacing Options” and select it.

Choose “Camera" and enable it.

Confirm and exit the configuration tool. You may be prompted to restart your Raspberry Pi.

Step 3: Install libcamera (if not already installed)

Open the terminal on your Raspberry Pi.

Update the package list with sudo apt update.

Install libcamera using sudo apt install libcamera-dev libcamera-apps.

Step 4: Test the Camera with libcamera

Open the terminal.

Run libcamera -l to list all available camera devices. Your OV5457 camera should be listed.

Capture a still image with libcamera -o test.jpg. This saves a photo named "test.jpg" in your current directory.

Record a video using libcamera --video --duration 10 -o test.h264. This records a 10-second video as "test.h264".

Step 5: Adjust Camera Settings (Optional)

libcamera allows adjustments to various settings like resolution and exposure. For changing resolution, use:

libcamera --width 1920 --height 1080 -o custom_resolution.jpg

Refer to the libcamera documentation for a full list of options and settings.

Step 6: Develop Your Application

With the camera and libcamera set up, you can develop applications using the camera. This includes writing scripts for automated tasks, integrating with other hardware, or developing a GUI for camera control.

Troubleshooting Tips:

Ensure the CSI cable is securely connected to both the Raspberry Pi and the camera module.

If the camera is not detected, restart your Raspberry Pi after enabling the camera interface.

Consult libcamera documentation and Raspberry Pi forums for solutions to specific issues or advanced control techniques.

By following these steps, you should be able to successfully set up and use the OV5457 camera with your Raspberry Pi using the CSI interface and libcamera software.
