Device and method for angle measurement based on inlaid graphic information processing technology

The invention relates to a device and a method for angle measurement based on an inlaid graphic information processing technology. Light emitted by the device for angle measurement based on the inlaid graphic information processing technology passes through an eyelet above a collimator, lights into the collimator, passes through a beam splitter prism, then passes through an objective lens to a reflecting surface need measuring. The light reflected by the reflecting surface passes through the beam splitter prism to a complementary metal-oxide-semiconductor transistor (CMOS) imaging module. The CMOS imaging module receives reflecting light spot images and transmits the reflecting light spot images to an inlaid central processing unit and a photoelectricity touch display device through a peripheral interface circuit. The method for the angle measurement based on the inlaid graphic information processing technology comprises that the inlaid central processing unit carries out preprocessing on collected images of reflecting light spots of two detection surfaces, uses characteristics of the strength and the shapes of the light spots to search the light spots in the images, locks detected target areas, accurately positions the light spots, computes the relative position relationship between the light spots according the two images of the reflecting light spots, and obtains a deviation angle between the two detection surfaces. The device and the method for angle measurement based on the inlaid graphic information processing technology is capable of conveniently, accurately and rapidly detecting relative angle measurements between surfaces.
