Title: Device for detecting inter-vehicle distance
Inventor: KATSUNO TOSHIYASU
IPC: G01C3/06
Filed: 1991-10-14
Abstract: PURPOSE:To calculate an accurate inter-vehicle distance when detecting the distance to a vehicle ahead using a pair of CCD sensors, even if plural amounts of deviation exist at which the degree of correlation is at its minimum. CONSTITUTION:An image of a vehicle ahead which is obtained by a pair of CCD sensors 1a, 1b is digitally converted by a signal processing portion 14 and is inputted to a microcomputer 24. The microcomputer 24 calculates the degree of correlation according to a signal from the (a) bit width of the CCD sensors 1a, 1b. When a plurality of bit shifts at which the degree of correlation is at its minimum exist, the difference (b) between the shifts is added to the window shift (a) of the previous time and a CCD output of (a+b) width is reprocessed to calculate the degree of correlation. When the amount of bit shifts is one or plural and the difference between degrees of correlation is large, the amount of bit shift with the smaller degree of correlation is identified as the true amount of deviation and then the inter-vehicle distance is calculated.
