Arducam 1MP*4 Quadrascopic Monochrome Camera Bundle Kit for Raspberry Pi, Four OV9281 Global Shutter Camera Modules and Camarray Camera HAT

Overview:

This Arducam quadrascopic camera bundle incorporates four 1MP OV9281 global shutter cameras, and the cutting-edge MIPI camera breakthrough from Arducam - The Arducam Camarray HAT. As the upgraded version of Arducam Synched Stereo Camera 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 camera port on prevailing single-board computers like Raspberry Pi. Also, as the Camarray HAT releases, Arducam starts to support a variable baseline for multi-camera applications with some modified Arducam camera modules, such as those OV9281 ones included in this bundle. You can kick off your prototyping for multi-camera applications and then decide the optimal baseline. Contact us for customized requests if needed.

Features:

• 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.
• Mono 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.
• 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 quadrascopic vision.

Applications:

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

Specifications:

*: JetPack4.6/L4T32.6.1 on NVIDIA Jetson Nano/Xavier NX

Package Including:

• 4 pcs 1MP OV9281 global shutter camera module with low distortion M12 lens
• 1 pcs Arducam Camarray quadrascopic stereo camera HAT
• 4 pcs 150mm/6inch 22pin to 22pin camera cables
• 1 pcs 300mm/12inch 15pin to 22pin camera cable
• 1 pcs 73mm/2.87inch 15pin to 22pin camera cable
• 4 pcs M2.5*10mm Nylon Hex Standoffs
• 4 pcs M2.5 Nylon Nuts
• 4 pcs M2.5*6mm Nylon Screws

Notes:

• 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.
• 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.
