Abstract

The invention discloses a apparatus and method for template reconstruction based on two-dimensional linear transformation. Firstly, a modifying unit modifies a first template of a positioning algorithm to obtain a second template. Holding a second template for training data and outputting a two-dimensional linear transformation matrix corresponding to the second template; Secondly, when the firsttemplate of the positioning algorithm is modified, the notification unit sends a reconstruction instruction to the reconstruction unit. The reconstruction unit reconstructs the template of the visionalgorithm based on the two-dimensional linear transformation according to the new two-dimensional linear transformation matrix. By adopting the device and the method of the present application, templates of other vision algorithms based on two-dimensional linear transformation are passively modified according to the templates of the modified positioning algorithm, thereby reducing the programmingamount and the data processing amount of software in the system and reducing the maintenance cost of the system. At the same time, for the distributed visual software which can be debugged independently, it avoids the abnormal situation that only the location algorithm is modified but not the corresponding other visual algorithms.

Description

technical field [0001] The present application relates to the technical field of visual image detection, in particular to a template reconstruction device and method based on two-dimensional linear transformation. Background technique [0002] In recent years, visual image detection technology has developed rapidly. The vast majority of visual image inspection systems involve positioning algorithms and other visual algorithms such as line finding, circle finding, and code reading. Among them, the main idea of ​​the positioning algorithm is to match one or more real-time images with the training template in the real-time image, and output the positioning result including matching scores, positions, angles and many other information. The two-dimensional linear transformation matrix in the positioning result refers to the matrix representing the rotation angle and translation size between the real-time image and the training template. [0003] The two-dimensional linear trans...
