OPERATION CONTROL MAP, DISPLAY UNIT, AND WHITE LINE DETECTION APPARATUS

摘要

An operation control map of a white line detection apparatus, provided with a white line detection portion (5) that detects a white line on a road based on a captured image of the road surface, that references the operation control map (9) to determine whether to allow operation of the white line detection portion (5). The operation control map, includes a region (10) in which operation of the white line detection (5) is allowed, and a region (11) in which operation is not allowed, based on the gain of a road surface image signal and the temperature of a road surface imaging portion (3). The allowed region (10) is set if the reduced accuracy of white line detection, due to the thermal noise generated in the solid-state imaging sensor, falls within an acceptable range, and the disallowed region (11) is set if the reduced accuracy of white line detection falls outside of the acceptable range.
