The invention discloses a control method of intelligent traffic light based on image processing, which sequentially comprises an image collecting step, an image processing step and a green light control step; when in use, the control method specifically comprises the steps of: firstly, collecting digital image information by an image collecting module; and then, graying and denoising by an image processing module to obtain a pre-processed image; subtracting the current frame of pre-processed image with the latest background to obtain a differential chart, and obtaining a black and white binary chart according to a threshold value; performing morphological reinforcement to obtain a current frame of traffic flow information; finally, obtaining a green light time by a fuzzy control module according to the former frame of traffic flow information, the current frame of traffic flow information and a fuzzy control rule. The design of the invention has the advantages of strong flexibility, low installation and application costs, extensive application range, and capability of realizing efficient, intelligent and practical traffic light control.
Description
technical field [0001] The invention relates to a control method of an intelligent traffic light, in particular to a control method of an intelligent traffic light based on image processing, which is particularly suitable for realizing high-efficiency, intelligent and practical control of the intelligent traffic light. Background technique [0002] At present, the traffic light control methods used in China are mainly divided into timing distribution method, induction control method and monitoring room control method. [0003] The timing distribution method refers to the control of traffic signals according to the preset timing scheme, also known as cycle control. The equipment required by the timing distribution method is simple, the investment is the least, and the maintenance is convenient. It is a widely used basic control method and is suitable for traffic conditions where the traffic flow changes relatively regularly. However, it lacks flexibility. For example, it is ...
