A Laser Projection Device for Locating Points on the Plane Object

摘要：

　　Digital image processing technology can extract the main feature of an image.In order to achieve the interaction between virtual points and plane objects, we propose the equipment for indicating points on the plane object using laser projection.We designed the equipment with a bracket, stepper motor, two-dimensional turntable, PC control unit, and a laser pointer.Next, we analyzed the mathematical model of the equipment and developed an algorithm for solving the motor rotation angle.Finally, we verified our design with an image.Here, we develop a system that can control a laser projection to a specified location by adjusting coordinates of virtual points on a computer.
