The invention belongs to the field of machine vision, and particularly relates to a strip steel moving target tracking method under a shielding condition. The method comprises the following steps: acquiring a moving video of strip steel on a roller way, fusing color, texture and edge characteristics by using a Camshift moving target tracking algorithm with high calculation efficiency and good robustness, and predicting the position of the strip steel by using a BP neural network and a Kalman filter when water vapor occurs or equipment shields the strip steel, thereby completing the detection and tracking tasks of the strip steel. According to the method, the defect that the tracking precision is low due to the fact that a traditional Camshift algorithm carries out tracking through a singlefeature is effectively overcome, a solution is provided for the problem that the strip steel is shielded, the tracking target is prevented from being lost, and the tracking stability and tracking precision of the moving target under the complex background are improved.
Description
technical field [0001] The invention relates to the field of machine vision, in particular to a method for tracking a steel strip moving target under occlusion conditions. Background technique [0002] The iron and steel industry is an important basic industry of the national economy and one of the basic industries of all industrialized countries. Hot-rolled steel strip is the main product of iron and steel enterprises, and is widely used in various industrial fields such as machinery, construction, national defense, and aerospace. Hot rolling of strip steel is an important link in steel processing, and it is also the production link most prone to quality problems. The strip moves on the roller table and is transported to the rolling mill for reciprocating rolling and then transported to the finishing process after rolling. In the production process of strip steel, operators need to conduct real-time observation and monitoring in order to understand the location and state ...
