Abstract
A superimposition device of virtual guiding indication and reality image includes at least an image capturing device, a processor, a graphic processing unit (GPU), and a display device. The image capturing device captures reality image including instant scene. The processor receives the reality image and obtains height variation information. The GPU performs image correction processing on the reality image to obtain corrected image, generates updated transformation matrix according to the height variation information, and performs inverse perspective projection transformation by using the updated transformation matrix to generate bird's-eye view image of the corrected image and superimposes virtual guiding indication on the bird's-eye view image and performs perspective projection transformation on the bird's-eye view image to transform the bird's-eye view image into three-dimensional (3D) navigation image which includes the guiding indication. The display device displays the 3D navigation image which superimposes the virtual guiding indication into the reality image.
