Abstract

The invention discloses a safety helmet wearing condition monitoring method on a construction site. The hardware used in the monitoring method at least comprises a high-speed spherical camera, a monitoring device and a display device. The monitoring method at least comprises the steps of monitored image collection, monitored image processing and data statistics and display. Monitored image collection comprises the step of controlling the camera to carry out continuous shooting. Monitored image processing comprises the steps of target marking and safety helmet recognition, wherein target marking comprises the steps of obtaining a binaryzation current foreground and marks and tracking the movement target of a representative. Safety helmet detection and recognition are based on target marking, and data statistics and display carry out statistics and calculation according to safety helmet detection and recognition. According to the monitoring method, the detection method based on vision is used for monitoring the safety helmet wearing condition in an inlet of the construction site, and the monitoring method can achieve automatic detection and monitoring.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a monitoring method for wearing a safety helmet at a construction site. Background technique [0002] As a personal head protection product, the safety helmet can effectively prevent and reduce the injury to the human head when the operator encounters falling objects or self-falling during production operations. It is a necessary safety measure for construction workers on road construction sites to wear safety helmets, which can protect the personal safety of construction workers to a certain extent. It is of great significance to detect and count the number of people wearing safety helmets of various colors on the road construction site. Through the statistics of the construction personnel wearing safety helmets of different colors entering and exiting the construction site, it is convenient to realize the reasonable allocation of resources and effectively carry out personnel management; ...
