In this study, the method to measure the distance from the robot to the football or to the white lines for robot contests by single CMOS image sensor was proposed. It is possible to calculate the distances based on an image from the CMOS sensor when the sizes and the shapes of the targets to be recognized are known previously. The properties of the method were shown through the results of the preliminary tests for the distance from the CMOS image sensor to the football.
