Method for monitoring vehicles in construction site

Abstract

The invention discloses a method for monitoring vehicles in a construction site. The method includes the steps that firstly, a high-precision monitoring area background is obtained with a Gaussian background modeling method; secondly, a background differencing method is used for extracting moving objects in cooperation with a binaryzation method; thirdly, vehicle targets and pedestrian targets are distinguished, and the vehicle targets and the pedestrian targets which are attached are distinguished according to distribution characteristics of holes of the moving objects in the main axis direction; then either the vehicle targets are engineering carts or mini-sized motor vehicles is judged according to the size characteristics and the shape dispersion characteristics of the vehicle targets; virtual detection line method speed calculation based on computer vision is further carried out on the vehicle targets, and snap shooting and alarming are carried out when some vehicle target is overspeed. The method has the advantages that operation is simple, convenient and orderly, monitoring results are reliable, the manual monitoring cost is reduced, the moving objects entering and exiting from the construction site can be intelligently distinguished, the functions of conducting storing, displaying, alarming and the like on monitoring information are achieved, and the requirement for automatically and efficiently monitoring the vehicles in the large construction site can be met.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a vehicle monitoring method at a construction site, and belongs to the technical field of monitoring. Background technique [0002] In large-scale construction sites, there are a large number of construction vehicles and other vehicles entering and leaving the construction site, and the management of vehicles on the construction site is directly related to the order and safety of the construction site. For example, in a construction site, if the number of vehicles entering the construction site is not controlled, it will cause internal congestion at the construction site; and if there are too many non-construction vehicles entering the construction site, it will also cause certain confusion; problems such as these need to Solve it through reasonable supervision of construction site vehicles. [0003] However, at present, the supervision of vehicles on the construction site still mostly rel...

AI Technical Summary

Problems solved by technology

For example, in a construction site, if the number of vehicles entering the construction site is not controlled, it will cause internal congestion at the construction site; and if there are too many non-construction vehicles entering the construction site, it will also cause certain confusion; problems such as these need to Solved by reasonable supervision of construction site vehicles

[0003] However, at present, the supervision of vehicles on the construction site still mostly relies on manpower, such as taking measures such as manually recording the number of vehicles entering and leaving, the type of vehicles, and whether the vehicles are speeding. There are also many safety hazards
