The 3D Measuring Method Based on the Color Coding Grating

Abstract:

Article Preview

This paper puts forward a new method of 3D measurement which based on the color coding structure light technology, projects the specific color coding grating to a Calibration board in RGB three color space, gets the straight line equation of grating which projected to Calibration board in the world coordinate system, obtains each projection plane of code through plane fitting, then joins the projection planes and the object imaging straight strips which through the camera focus, it can be get that the three dimensional coordinates of the objects. This method is simple and reliable; only need one camera and one projector without scanning; only one image is needed to get the information of a full frame depth image. It is suitable for high speed, real-time online measurement.
