PURPOSE: A preprocessing device in a stereo matching system is provided to reduce the size of the system by using only four of nonvolatile memories. CONSTITUTION: A preprocessing device includes a preprocessing unit(10) and a nonvolatile memory unit(20). The nonvolatile memory unit includes four of storage units(21-24) and stores coordinate information of a stereo camera. The preprocessing unit designates an address of a new pixel by using the coordinate information and corrects right and left images received from the camera by using the address. [Reference numerals] (11) Left address generating unit; (12) Right address generating unit; (13) Left image storage unit; (14) Right image storage unit; (15) Left interpolating unit; (16) Right interpolating unit; (21) Left column position storage unit; (22) Left row position storage unit; (23) Right column position storage unit; (24) Right row position storage unit; (AA) Left image; (BB) Left weight; (CC) Right image; (DD) Right weight |
