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.
完全同步：四個攝像機的幀在硬件級別上同步，不需要考慮通過時間戳等額外的同步方案。 - 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.
單全局快門：以清晰的圖像拍攝高速移動的物體。避免滾動偽影，以獲得比滾動快門 Pi 相機更準確的完整圖片。 - 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.

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.
- The Camarray HAT is not sold alone for the following reasons:（Camarray HAT 不 單獨出售， 原因如下）
- 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. （無法直接與其配合使用）
- 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.（不一定通用）
Customization is required if you have extra requirements as the following:
- You need the camera module to run on other Video Modes and Frame Rates.
- You need to trigger the camera with an External Hardware trigger.
- You only want three images or one image.
