Embodiment Construction

[0011] Such as figure 1 Shown is the application environment diagram of the preferred embodiment of the image matching system of the present invention. The image matching system 200 is installed and runs on the computer 20 . The computer 20 is connected with the database 10 and the display device 30 .

[0012] The database 10 is used to store images to be matched and template images. In this embodiment, the image to be matched is an image of an object captured by an image capture device, such as a charge coupled device (CCD). A template image refers to a sub-image that includes a target object.

[0013] The computer 20 executes the image matching system 200 to search for the target object in the template image in the image to be matched, determine the coordinates, direction and other information of the target object in the image to be matched, and store the matching result information in the database 10 .

[0014] The display device 30 is used for displaying matching proce...

Abstract

The invention provides an image matching system applied to a computer. After the computer executes the image matching system to perform binarization processing on an image to be matched and a template image, outline characteristic points are extracted from the image to be matched and the template image, a geometric figure is obtained according to the fit of the outline characteristic points, the image is matched based on the geometric figure, and the coordinate, direction and other information of a target object in the image to be matched are determined. The invention also provides an image matching method. The image matching system and the image matching method can reduce the computed amount in the image matching process and improve the image matching speed.

Description

technical field [0001] The present invention relates to an image recognition system and method, in particular to an image matching system and method. Background technique [0002] A machine vision system refers to a device that acquires an image of an object through an image capture device and processes the image to obtain the required information for controlling the movement of field equipment. In the machine vision system, the recognition and positioning of objects in the image is one of the key links. The current image matching method is generally based on the pixel value of the image, which has a huge amount of calculation and slow matching speed. Contents of the invention [0003] In view of the above, it is necessary to provide an image matching system that can improve the speed of image matching. [0004] In addition, it is also necessary to provide an image matching method that can improve the image matching speed. [0005] An image matching system installed on ...
