Summary:In a traditional catadioptric calibration process, a calibration target placed in different views is required and it leads to complexity in the calibration process. In order to simplify the calibration process of a non-central catadioptric vision system, we developed a local target reconstruction method used a circle-square-combined target. Each circle-square on the target is regarded as an independent sub-region. According to the local mapping of the sub-regions, these can be reconstructed based on the curvature of a curved mirror and the characteristics of the circle-square-combined target. The overall procedure requires a single image, due to the reconstructed sub-regions. To evaluate the performance of the proposed method, real experiments have been carried out and the results show that the proposed method is reliable and efficient.
