Title: Method and device for judging visibility range by picture
Inventor: ISHIJIMA TOSHINOBU
IPC: G08G1/04
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To accurately judge the visibility range day and night and to judge it by the picture of one general-purpose TV camera. SOLUTION: A picture photographed by one camera 1 is stored in a picture memory and a picture memory buffer. The luminance value of a set area A is measured from the picture in the picture memory. An average value of luminance values of all picture elements in the set area A is compared with a threshold. If it is equal to or larger than the threshold, a visibility range flag is set to one. When a vehicle is detected in a set area B, individual processing for day or night is executed. When a set time has elapsed independently of vehicle detection, total OR of visibility flags in the past prescribed time is calculated, and the visibility range is judged as good in the case of one and is judged ass defective or impossible by day and night in the case of 0. This visibility range judging result and the visibility range judging result of individual processing are judged synthetically.
