Summary:
This paper provides a new strategy for estimation of absolute depth perception to objects from a sequence of successive frames by a single rotational camera. Motion parallax which is a big cue for depth perception in monocular vision is used to estimate depth of object point present in the scene. In the simulation, the camera model is designed to accelerate along a trajectory of a circle by a constant radius. The transformation between global coordinate and camera coordinate is performed to obtain the coordinate of objects on the successive images. So the objects’ acceleration on the image can be estimated. In the algorithm we only use the object acceleration on the image and the camera’s acceleration to estimate the absolute depth from objects.
