Abstract

The present invention relates to a method for calibrating a spray tool mounted on a mobile marking robot. The method comprises taking a photo with a handheld camera device of a preset pattern of painted lines marked by a spray tool of a mobile marking robot, with complementary IMU metadata of the handheld computing device; using said IMU metadata to create an image by rectifying the captured photo to get a projection that matches the plane of the surface on which the lines are painted; using machine vision to recognize and measure the painted lines on the rectified image; and using the measurements to calibrate the spray tool of the mobile marking robot.
