Abstract
PURPOSE:To detect an obstacle for a working vehicle accurately by providing a predetermined reference color to an obstacle to be detected then taking color photography of a predetermined dangerous area and judging whether the reference color exists in the dangerous area. CONSTITUTION:Objects to be detected, i.e. workers, 10 are applied with helmets 12 or work suits 14 of preset reference color. A color photography means 7 having view in the dangerous area is arranged on a working vehicle 11. An object, i.e. a worker, 10 having reference color is detected through a color judging means 2 based on an image taken through the color photography means 7. Then an alarm is provided to the worker 10 corresponding to a detected signal, or the working vehicle 11 is stopped automatically. Preferably, a particular color which does not exist in the working area of the working vehicle 11 is employed as the reference color. Consequently, only a particular object 10 is detected accurately and erroneous operation of alarm can be prevented.
