STEREO IMAGE PROCESSING DEVICE AND STEREO IMAGE PROCESSING METHOD

摘要

To provide a stereo image processing device and a stereo image processing method that can suppress a decrease in the determination accuracy of parallax for an identical object due to mixture of noise and the like, the device includes a pair of imaging units 101a, 101b; a similarity calculation unit 106b that calculates similarity for each parallax for the pair of images; a parallax calculation unit 106c that calculates parallax for an identical object on the basis of the similarity for each parallax; a parallax data buffer unit 105 that stores data on the parallax; a speed detection unit 107 that detects a moving speed of the pair of imaging units 101a,101b; and a parallax prediction unit 106a that calculates a predicted parallax value on the basis of the moving speed and past data on parallax stored in the parallax data buffer unit 105. The parallax calculation unit 106 calculates parallax for an identical object on the basis of the similarity for each parallax and the predicted parallax value.
