Uncalibrated rectification #8

Closed Tord-Zhang closed 1 year ago

Tord-Zhang commented 1 year ago

Hi, If I get two images not perfectly rectified, i.e., there are negative disparities, is it possible to rectify there two images with this code?

decadenza commented 1 year ago

If you have the original images and the calibration parameters, yes. Since your title is "uncalibrated rectification" I suspect you don't have these. Could you share something more?

Thanks for your response! By "uncalibrated rectification", I mean that I got two images captured by camera with unknown intrinsics. And also I do not know the distance these two camera. It is possible to rectify?

Unfortunately not, this code starts from known calibration intrinsic and extrinsic parameters. If possible, is always better to calibrate to improve the quality of the final 3D reconstruction. I suggest to search for the appropriate algorithm (maybe you may start from scholar.google.com). There are plenty that are able to estimate the parameters.

Good luck.
