Automatic teaching system

Provided is an automatic teaching system capable of easy automation even if there is a small quantity and wide variety of products to be processed by polishing or painting. The present invention is characterized by comprising a three-dimensional shape measurement device, a reference marker, an image analysis device, and a robot control device, wherein the three-dimensional shape measurement device acquires the shape data of an area to be processed in an object to be processed with respect to the reference marker, and the image analysis device divides the shape data of the area to be processed into a plurality of continuous reference planes according to a predetermined algorithm. For each of the reference planes, an operation path program for operating the polishing or painting device of a robot is automatically generated according to a predetermined operation path generation rule, and the operation path program is sent to the robot control device. 本发明提供在实施研磨或涂敷的处理对象物少量且多个品种的情况下也能容易谋求自动化的自动教学系统。其特征在于具备：三维形状测量装
