Problems solved by technology

Although this method uses a star structure to express the spatial structure of the target, and uses distance transformation technology for fast target detection, there are still shortcomings in this patent application: the use of a star structure to represent the spatial structure of the target is not accurate enough, which will lead to detection results Not accurate enough; in addition, before using distance transformation to detect the target, it is necessary to obtain the detection cost map of the target as a whole and each part of the target, which will seriously affect the detection efficiency
Although the k-fans structure used in this method can express the spatial structure of the target more accurately, there are still shortcomings: when there is a loop in the k-fans structure, the distance transformation technology cannot be used for fast target detection. This seriously affects the scope of application of this method

Abstract

The invention discloses a method for detecting targets based on components. The method mainly solves the problems that a target component detection algorithm is high in calculating complexity, narrow in application range, and inaccurate in target space structure. The method includes the steps of marking a training image; constructing a target space structure; calculating space structure model parameters; calculating appearance model parameters; transmitting model parameters; collecting a detected image; initializing target-detected parameters; obtaining central component transmitting position coordinates; determining whether to record the central component transmitting position coordinates for the first time; obtaining a similar component position coordinate set; obtaining a final component position coordinate set; and displaying detected results. The method for detecting targets based on components accurately expresses the target space structure, improves the detection speed and extends the application range of the target component detection algorithm.
