[0056] refer to figure 1As shown, the first embodiment proposed by the present invention is an image matching method. The image matching method uses a depth module to capture images. The image matching method includes:

[0057] Step S10, controlling the depth module to collect a target image of the target area, and obtaining the first depth information corresponding to the target image, the depth module is a TOF (Time of flight, time of flight) camera, and the depth module The principle of the group is to emit light pulses, then record and receive the light reflected from the surface of the object through the sensor, calculate the round-trip distance of the light pulse by multiplying the time by the speed of light, and obtain the depth distance of the object, and set the target area to facilitate timely and accurate acquisition of the target For the image, the target image is taken as a standard, the target image is captured by the depth module, the first depth information is ...

Abstract

The invention discloses an image matching method, device and equipment and a computer readable storage medium. The image matching method adopts a depth module to shoot an image, and the image matchingmethod comprises the following steps: controlling the depth module to collect a target image of a target area, and obtaining first depth information corresponding to the target image; controlling thedepth module to search and identify the matching source area, and obtaining second depth information after search and identification; and according to the first depth information and the second depthinformation, obtaining a matching image correspondingly matched with the target image. According to the technical scheme, the three-dimensional depth information of the image can be shot, and the images in different directions and orientations can be effectively recognized and obtained.

Description

technical field [0001] The present invention relates to the technical field of image matching and recognition, in particular to an image matching method, device, equipment and computer-readable storage medium. Background technique [0002] Image matching is to find another template image in an image. There are many application scenarios of image matching, such as image retrieval and target tracking. However, the existing image matching algorithms can only be calculated based on two-dimensional images. If the image The up, down, left, and right settings are reversed, and the existing algorithms cannot effectively distinguish them. Especially in the packaging industry, there are requirements for the direction of instruction manuals or trademarks. If the packaging products are stacked together, it will increase the difficulty of matching the direction of the trademark. It is difficult to collect and grasp the posture of packaging products from time to time. Contents of the in...
