Abstract

An automatic re-calibration for mobile vision is presented. In this technique, the vision parameters are determined by means of a Bezier network. This procedure is carried out by image processing of a laser line. From the network structure, the initial calibration and the online re-calibration are performed. The proposed technique avoids calibrated references and physical measurements, which are used in traditional calibration. Thus, the proposed re-calibration improves the accuracy and performance of the mobile vision. This procedure represents a contribution in the re-calibration. To elucidate this contribution, an evaluation is performed based on the re-calibration methods. Also, the time processing is described.
