Focal inverse distance transform map

WebFeb 14, 2024 · Recall that adjusting the focal length will proportionately scale the points on the image plane. Now, suppose we scale the entire scene, X by some factor kand, at the same time, scale the camera matrices, P by the factor of 1/k, the projections of the scene points in the image remain exactly the same. x = PX = (1/k)P * (kX) = x Web(d) 就是本文提出的焦点反距离图 (FIDT: Focal Inverse Distance Transform)，首先说一下标注真值图的生成方式。 先计算每个像素点与其最近标注点的欧式距离： 然后就可以先定 …
