Abstract

The invention provides a queue length automatic detection method and a queue length control method. The queue length automatic detection method comprises the following steps: detecting pedestrians based on a human body structure model algorithm; tracking the pedestrians through a feature online selection lifting algorithm; fitting out a queue shape of pedestrians through an RANSAC-based least square polynomial curve fitting method according to the detected pedestrians, and estimating the length of the queue; converting an image coordinate system into a world coordinate system through image calibration, and calculating the actual queue length; and calculating the length of the curve through curve fitting, and calculating the number of people in the queue according to the queue length and the distance between adjacent people in the queue. Through the queue length automatic detection method and the queue length control method of the invention, the length of a pedestrian queue in a monitoring scene can be detected quickly and accurately, the problem of target loss is avoided, and no pedestrian is missed in detection. Through real-time queue monitoring, passengers can move to a handling window with a shorter queue in a timely manner. Therefore, the problem of waiting in a queue is solved, and passengers can be better served.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a queue length automatic detection method and a queue length control method. Background technique [0002] In public environments such as airports, passengers often need to wait in line when checking in for boarding passes and entering security checkpoints. Due to the concentration of people, when the number of people is large, the waiting time for passengers in line will be prolonged, which will cause passengers' anxiety; at the same time, Passengers need to arrive at the airport a long time in advance to avoid flight delays, which greatly reduces the passenger experience. There are above problems in public places such as hospitals equally. [0003] The existing solution is that the staff of the airport use manual guidance to reduce the waiting time of passengers in line; since manual guidance is completely dependent on the staff's control of the situation on the spot,...
