Abstract

Wide-Angle Fovea Vision Sensor (WAFVS) is a strong solution to solve a severe problem of a pay-load in remote control of the planetary exploring rover. This vision sensor was originally designed and developed for multi-purpose use of a single vision sensor, taking into account advantages of the human eye's functions. It is characterized by its space-variant data acquisition property, i.e., the WAFVS captures a 120-degree wide-angle input image in which its resolution changes like the human visual acuity. As well-known, the human visual acuity is the highest at its central field of view (FOV) and decreases rapidly towards its peripheral FOV. Therefore, WAFVS makes it possible to observe a target in detail by its central field of view as observing the whole of environment by its wide field of view. Moreover, by combining with its view direction control, the WAFVS gets visual information more in detail by smaller data amount. Hence, the WAFVS performs better in data transmission and data storage. This paper proposes and discusses circular tessellation based on Advanced Wide Angle Foveated model, i.e., one of the foveation models, in order to achieve the space-variant data acquisition of the input image from the WAFVS.
