Abstract

The invention relates to the technical field of image processing, and provides a pantograph-catenary image registration method and device optimized by chaotic heuristic search, aiming at solving the technical problems of slow convergence speed and insufficient registration precision when artificial bee colony optimization algorithm is applied to pantograph-catenary image registration. For this purpose, the chaotic heuristic search optimized pantograph-catenary image registration method of the invention comprises the following steps of generating an initial population according to a preset reference pantograph-catenary image, wherein each individual in the initial population stores a predetermined number of registration parameters; optimizing the registration parameters of pantograph-catenary images by a chaotic heuristic search algorithm; obtaining the pantograph and catenary images to be registered by spatial transformation of the registration parameters. The invention can enhance thelocal search ability of the algorithm, accelerate the convergence speed of the algorithm, and improve the accuracy of pantograph-catenary image registration.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a pantograph-catenary image registration method and device for chaotic heuristic search optimization. Background technique [0002] With the continuous maturity of China's high-speed train technology, China's high-speed railway network is constantly growing. In the high-speed railway network, every running high-speed train needs to obtain electric energy through the sliding contact between the pantograph and the grid at all times. It can be seen that the pantograph-catenary system is an important part of the high-speed railway network system. However, as the speed of high-speed trains increases, the probability of pantograph-catenary failures will also increase. The failure of the pantograph-catenary system will bring great danger to the operation of the high-speed train. Therefore, pantograph-catenary fault detection is an important basic technology in high-speed train systems...
