Problems solved by technology

However, in the process of code word recognition, it may be affected by many factors, such as background information, noise, etc., and there will inevitably be some wrong code words
Subsequent 3D reconstruction and target recognition are carried out on the basis of correct recognition of codewords, too many wrong codewords will greatly reduce the accuracy of the final 3D information

Embodiment Construction

[0015] See attached Figures 1 to 5 , the present invention will be further described in detail below in conjunction with specific examples.

[0016] In one embodiment, the present invention discloses a symbol array structured light codeword correction method, the method includes the following steps:

[0017] S100: input code word image;

[0018] S200: For the codeword image, classify and mark the codeword according to the coding rule, and generate a corresponding marker point map;

[0019] S300: Perform correction processing on codewords based on the marker point map.

[0020] For this embodiment, it has set forth the basic principle of the present invention, that is, no matter what the encoding law of the codeword is, this embodiment is to use its existing encoding law to carry out the classification mark of the codeword image, Therefore, it is possible to carry out targeted correction on the codewords according to their different classifications in combination with corre...

Abstract

The invention discloses a symbol array structure light codeword correcting method. The method comprises the following steps: S100, inputting a codeword image; S200, about the codeword image, according to the coding rule, performing the classification marking to the codeword, and generating a corresponding mark point diagram; and S300, based on the mark point diagram, performing the correction processing to the codeword. The provided codeword correcting method is capable of greatly improving the accuracy and integrity of the codeword recognition, easily programming, and conveniently promoting in large-scale.

Description

technical field [0001] The invention belongs to the technical fields of image processing and computer vision. technical background [0002] Vision plays a very important role in human life. It is the most direct, easiest and most important means for human beings to observe and understand the world. Human beings obtain information about the world around them through their eyes, so as to understand and recognize the world. With the continuous development of computer technology, computer vision, as a new interdisciplinary subject, has developed rapidly in theory and practical application. Computer vision mainly uses computers to simulate human eyes, captures spatial scene information through cameras, and then processes the information to achieve the purpose of 3D reconstruction and object recognition. [0003] There are already many ways to obtain 3D information, which are mainly divided into contact and non-contact. The tactile three-dimensional measurement method has limit...
