Abstract

PURPOSE:To detect an obstacle for a working vehicle accurately and to prevent erroneous function by applying a specific reference color previously onto an object to be detected while furthermore taking a color photography of a predetermined dangerous area and judging whether the reference color exists in the dangerous area. CONSTITUTION:Objects to be detected, particularly workers, 10 are previously applied with helmets 12 or work suits 14 of reference color. A color photography means 7 having a view in a dangerous area is arranged on a working vehicle 11. An object 10 having reference color is detected through a color judging means 2 based on an image taken through the color photography means 7. An area judging means 6 detects whether the object 10 having reference color exists in the dangerous area. When an alarm is provided to the worker 10 or the working vehicle 11 is stopped automatically corresponding to a signal detected through an AND gate 8. Consequently, only a particular object 10 can be detected accurately and erroneous function of alarm can be prevented.
