Abstract

The invention relates to a robot vision tracking method and system. The method includes: obtaining a trained naive Bayesian classifier by utilizing a Monte Carlo algorithm and a compressed sensing theory according to a frame image at the moment t; sampling the frame image at the t + 1 moment to obtain a plurality of images to be tracked; using a Monte Carlo algorithm and a compressed sensing theory to perform dimension reduction on the plurality of images to be tracked respectively to obtain a compressed feature vector of each image to be tracked at the t + 1 moment; and inputting the compressed feature vector of each to-be-tracked image at the t + 1 moment into the trained naive Bayesian classifier, and performing target and background classification to obtain a tracking target at the t +1 moment. According to the robot vision tracking method and system provided by the invention, the Monte Carlo and the compressed sensing are combined, so that the vision tracking efficiency and reliability are improved.

Description

technical field [0001] The invention relates to the field of robot vision, in particular to a robot vision tracking method and system. Background technique [0002] In recent years, continuous progress in the fields of machine learning, cognitive science, and cognitive neuroscience has given great impetus to intelligent robots. Visual object tracking is one of the most widely used and important problems in computer vision, and is widely used in object monitoring, human-computer interaction, and medical imaging. Visual object tracking is by algorithmically estimating the object state in subsequent frames given the initial state (e.g., location and size) of the object in a video frame. Although object tracking has been studied for decades and has made great progress, it is still a very challenging problem. Many factors affect the performance of tracking algorithms, such as occlusions, object motion, and complex backgrounds. In recent years, many object tracking methods have...
