WebAbstract. This project implements feature point detection and its matching between stereo pair images from KITTI dataset. For a given input RGB image from left camera, the features which are described to be an image region that is salient, local, repeatable, compact and efficient, are identified and studied by visual inspection for unreliability on matching. Web2.3. Feature point matching After determining the scale and rotation information of the image feature points, it is necessary to determine the similarity between the feature point descriptors in the two different time images to determine whether they match. Suppose that feature point 𝑥 ç à,𝑚=1,2,⋯,𝑀 is extracted in image 𝐼 ç,
Web31 de out. de 2024 · When matching with MonoDepth, SIFT algorithm of OpenCV is used to extract feature points and compute descriptors which is similar to matching without MonoDepth. However, when it matches with adjacent images, it should compare the depth distance between the matched feature points, and we set the value as 35, which means …
