A traffic line recognition device includes: a traffic line region candidate extraction section that extracts a traffic line candidate, as a traffic line candidate, from a road image obtained by a TV camera installed on a vehicle; a two dimension/three dimension transform section that transforms two dimensional image coordinates of a pixel contained in the traffic line region candidate into three dimensional coordinates; a histogram production section that accumulates and projects the three dimensional coordinates onto a coordinate system in a direction crossing a road and produces a histogram in the direction crossing the road; and a traffic line judgment unit determines a traffic line based on that histogram.

Traffic line recognition device

A moving body measuring device, having an image taking unit for taking an image of a moving body, a controller for controlling the image taking unit and a frame memory for memorizing an image data of the image of the image taking unit, which processes the image data, detects the moving body and obtains an information of the moving body which comprises an existence domain setting circuit for previously setting an existence domain of the moving body extended along a moving path of the moving body based on the image data, a sampling circuit for sampling a data showing the moving body based on the image data in the existence domain, and a timewise data accumulating circuit for timewisely and continuously accumulating at every constant period, the data showing the moving body sampled by the sampling circuit which detects a timewise change of the moving body moving in the previously set existence domain.
