PROBLEM TO BE SOLVED: To provide an image processor for correcting the distortion of a picked-up image with higher accuracy.SOLUTION: An image processor 20 includes a first acquisition part, a second acquisition part, a corresponding point data retrieval part, a calculation part, a third acquisition part, a storage part 211 and an update part, the first acquisition part acquires a first picked-up image, and the second acquisition part acquires a second picked-up image. The corresponding point data retrieval part calculates corresponding point data in each of a plurality of feature points in the second picked-up image. The calculation part calculates a first correction parameter and a second correction parameter on the basis of a set of retrieved corresponding point data. The third acquisition part acquires temperature information showing the temperature of a stereo camera. The storage part stores correspondence information with the first correction parameter and the second correction parameter associated therewith in each of a plurality of kinds of temperatures. The update part associates the temperatures with the first correction parameter and the second correction parameter calculated by the calculation part, and updates the correspondence information stored in the correction parameter storage part.SELECTED DRAWING: Figure 1 |
