Homography shader
Web5 apr. 2024 · You have a homography h calculated from findHomography and you can use warpPerspective to transform the template to have the same perspective as the photo. Now you just need to invert the homography, and apply it to the photo instead of the template. Either use np.linalg.inv for that, or pass the WARP_INVERSE_MAP flag to … WebProjection Mapping Tests and Shaders using Unity 3D - Unity3DProjectionMapping/Homography.cs at master · …

Homography lets us relate two cameras viewing the same planar surface; Both the cameras and the surface that they view (generate images of) are located in the world-view coordinates. In other words, two 2D images are related by a homography H, if both view …
Web工程实践. If you have more than 4 corresponding points, it is even better. OpenCV will robustly estimate a homography that best fits all corresponding points. Usually, these point correspondences are found automatically by matching features like SIFT or SURF between the images. ''' pts_src and pts_dst are numpy arrays of points in source ...
