Arducam 1MP*4 Quadrascopic Camera Bundle Kit for Raspberry Pi, Nvidia Jetson Nano/Xavier NX, Four OV9782 Global Shutter Color Camera Modules and Camarray Camera HAT

Description

Overview
This Arducam quadrascopic camera bundle incorporates four 1MP OV9782 global shutter cameras, and the cutting-edge MIPI stereo camera breakthrough from Arducam – The Arducam Camarray HAT. As the upgraded version of Arducam Synched Stereo Camarray HAT, the Camarray further pushes the multi-camera limits and doubles the interfacing capabilities to allow 4 synchronized MIPI camera modules to be interfaced to a single MIPI CSI-2 slot on prevailing single-board computers like Raspberry Pi, Jetson Nano, and Jetson Xavier NX. Also, as the Camarray HAT releases, Arducam starts to support a variable baseline for stereo camera applications with some modified Arducam camera modules, such as those OV9782 ones included in this bundle. Since no shared camera board or clock-sharing soldering is required for the image sensors, you can kick off your prototyping for stereo camera applications and then decide the optimal baseline. This camera can only get four images. Arducam also accepts subsequent customizations for your stereo camera applications.

Applications

• Head, and eye tracking
• Gesture detection
• Motion detection
• 3D reconstruction
• Depth-related vision applications

Features

• Supports Multiple Platforms: This bundle runs four synchronous OV9782 cameras through a single connection with MIPI CSI-2 port, compatible with Raspberry Pi and Jetson Nano/Xavier NX, also can be extended to other platforms that have MIPI CSI-2 interface and standard Video4Linux2(V4L2) driver.
• Complete Synchronization: The frames of four cameras of this bundle are synchronized at the hardware level, extra synchronization scheme by time stamping or so does not need to be considered.
• Color Global Shutter: Shoot high-speed moving objects in crisp sharp images. Avoid the rolling artifacts to get a much more accurate complete picture than the rolling shutter Pi cameras. Frame Rate: 45fps@1280*4 × 800 on Jetson; 30fps@1280*4 × 800 on Rpi.
• Variable Baseline Extension: Compared to the fixed stereo camera module, this stereo camera bundle has higher flexibility. The separated cameras can be used with a variable baseline device and controlled through the computer control system to achieve rapid and dynamic interactive adjustment of the moving parts for multi-degree-of-freedom stereo binocular vision.
• Support Changing Frame Rate: You can change the frame rate from 5fps to 46fps. If the set frame rate exceeds the maximum value, it will work according to the maximum value. The same goes for the minimum value.

Specifications

Package Including

• 4 x 1MP OV9782 global shutter camera module with low distortion M12 lens
• 1 x Arducam Camarray quadrascopic stereo camarray HAT
• 4 x 150mm/6inch 22pin to 22pin camera cables

Note

• Raspberry Pi board and Jetson Nano/Xavier NX are not included in the package.
• This bundle kit is not recommended for Raspberry Pi Zero.(Due to the limitation of the memory)
• The driver of the kit is mainly developed based on the Raspberry Pi/Nvidia Jetson official board, and there is no guarantee that the third-party board can be used (due to the different allocation of hardware resources, it is not compatible with the driver)
• The OV9782 cameras in this kit is a special version and cannot be used on Raspberry Pi or Jetson directly.
• This camera relies on kernel drivers to work – one kernel version, one camera driver. Up or downgrading your OS leads to a kernel bump, and you may need to re-install a matching driver.
• The I2C signal and clock of each camera are fully synchronized . It is unavailable to capture the same frame of images at different exposure times for each camera.
• This kit uses 1MP OV9782 sensor. Due to the limitations of the sensor, the camera may experience lens shading under low exposure conditions.
• This camera is released for the official NVIDIA® Jetson™ Developer Kit, and it does not guarantee to support other third-party boards.
• The Camarray HAT is not sold alone for the following reasons:
  1. Most of the cameras on the market are not designed for synched stereo uses. We’ve modified our camera modules specifically for the Camarry HAT. Your own V1, V2 or HQ camera modules won’t directly work with it.
  2. The Camarray HAT requires different firmware for different Image sensors that are not natively working with your embedded systems. Your own OV9782 camera modules won’t directly work with it, and they are not easily interchangeable.

Customization is required if you have extra requirements as the following:

1. You need the camera module to run on other Video Modes and Frame Rates.
2. You need to trigger the camera with an External Hardware trigger.
3. You only want three images or one image.
