Method and system for improving pedestrian number detection accuracy, medium and device

The invention relates to the technical field of image recognition, and particularly provides a method and a system for improving the pedestrian number detection accuracy, a medium and a device. The objective of the invention is to solve the problem of inaccurate pedestrian number detection in the prior art. In order to achieve the purpose, the method comprises the following steps: inputting a to-be-recognized picture with a shot pedestrian into a pedestrian detection model; obtaining a real human body detection frame of the pedestrian through a human body branch calculation channel of the pedestrian detection model; obtaining a real head detection frame and a matched human body detection frame of the pedestrian through a head branch calculation channel of the pedestrian detection model, carrying out intersection-union correlation on the real human body detection frame and the matched human body detection frame, and removing repeated matched human body detection frames; and counting the sum of the real human b
