Access to raw data

Post by rkalghatgi »

How is raw image data accessed through OpenCV? Is each camera seen as a usb device or something? I am planning to write my own calibration algorithms.

Hello Rkalghatgi,
Yes, it is accessible.
If you'll use Python, you can use the PiCamera library to access the frames data.
WIth the C you can use either mammal approach, or pipe approach, or direct access to the video of each camera (but in this case streams are not synchronized).
You can find some tricks in this article, where we compared the Python and C++ approaches.
