Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] The invention provides a graphic image recognition method and a recognition system. The recognition method is: adding infrared reflective materials on the surface of props; The difference determines the height of the props at the corresponding coordinates; the external adjustable length, width and height parameters are used to classify...

Abstract

The invention discloses a graphic image recognition method and recognition system. The method comprises the steps of calculating a mean background depth map of a platform; acquiring an infrared imageand a real-time depth image of a measured prop covered with an infrared reflective material on the collection platform, and preprocessing to obtain an infrared binary image; automatically calibratingand aligning the projection image and the infrared binary image; identifying coordinates and length and width values of the infrared binary image; performing difference operation on the mean background depth map and the real-time depth map to obtain a difference depth map; determining the height value of the measured prop in the difference depth map according to the coordinate value recognized bythe infrared binary image; classifying the measured props by externally setting geometrical parameters of each measured prop; and mapping the coordinates of the recognition point of the measured propto the display coordinates of the projection image, and sending the category of the measured prop and the transformed coordinates to interactive projection effect software. According to the method, the graphic image can be simply and quickly recognized, the recognition process is real-time processing, and the graphic can be immediately recognized when the graphic is changed.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a graphic image recognition method and a recognition system. Background technique [0002] Computer image recognition technology is a technology that uses computers to process, analyze and understand images to identify targets and objects in various patterns. The research problem of image recognition is how to use computers to replace humans to automatically process a large amount of physical information, solve the problem that humans cannot recognize or recognize too much resources, and thus liberate human labor to a large extent. [0003] Traditional cameras can only obtain the two-dimensional plane and color information of the environment. In order to compile computer programs that simulate human image recognition activities, people have proposed different image recognition models, such as template matching models. This model believes that to recognize an image, the...
