OpenCV: Feature Matching + Homography to find Objects

Web19 de fev. de 2024 · OpenCV robustly estimates a homography that fits all corresponding points in the best possible way. The point correspondences are found by matching features like SIFT or SURF between the images.

Web单目三维重建一、单目三维重建概述客观世界的物体是三维的，而我们用摄像机获取的图像是二维的，但是我们可以通过二维图像感知目标的三维信息。三维重建技术是以一定的方式处理图像进而得到计算机能够识别的三维信息，由此对目标进行分析。 Web24 de mar. de 2024 · kbarni February 22, 2024, 8:11am 2. The homography function needs the correspondence of 4 points. The linked tutorial uses the first corner for every marker to get the 4 points. However if you take all the 4 corners, you can obtain a total of 8 corners from the 2 markers. That should be enough to compute the homography.
