Slant estimation for active vision using edge directions in omnidirectional images

In this paper, we propose a novel method to estimate the slant of omni-directional image sensors which can acquire images of an environment with a FOV close to 360◦×180◦. The proposed method consists of two steps: a low resolution voting followed by a least squares method (LSM). First, the direction of each edge pixel in the omni-directional image is… (More)
