About the camera calibration

[ZhaungbiaoXiu]

I see that you are using an industrial camera with a resolution of 40963000, and the model input image resolution is 10241024. So, when calibrating the camera, do you first crop the image？

In practice, we implement calibration on 4096x3000 images and crop the images before they are used as our input.

Okay, thank you for your answer! I have another question about image cropping strategies: during the pre-processing stage, should we crop the original resolution image directly, or should we first scale it proportionally and then crop it?

Both strategies work when the extrinsic parameter is processed correctly.
