In this paper we propose a specialized hardware architecture for the real time visual navigation of a mobile robot. The adopted navigation method is based on a two-steps approach. Features are extracted and matched over an image sequence which is captured by a video-camera (mounted on a mobile robot) during its motion. As a result, a 2D motion field is recovered and used to extract ego-motion parameters. Our hardware implements the first step of the method, which consists of feature extraction and raw match computation by means of radiometric similarity computation. Real time performances are allowed since a 40 MHz processing rate is achieved.

Abstract

In this paper we propose a specialized hardware architecture for the real time visual navigation of a mobile robot. The adopted navigation method is based on a two-steps approach. Features are extracted and matched over an image sequence which is captured by a video-camera (mounted on a mobile robot) during its motion. As a result, a 2D motion field is recovered and used to extract ego-motion parameters. Our hardware implements the first step of the method, which consists of feature extraction and raw match computation by means of radiometric similarity computation. Real time performances are allowed since a 40 MHz processing rate is achieved.
