Abstract

The invention discloses an early warning method of overloading of a tourist footbridge in a scenic area. The method is characterized by relating to a monitoring camera, a video acquisition card, a monitoring host, a displayer and a warning loudspeaker box, a people number estimation method is adopted for operation of the monitoring host, the monitoring camera is installed on one side of the footbridge, a code module for people number estimation operates on the monitoring host, an image is processed through an image acquisition module, an image segmentation module, an image filtering module and a people number estimation module, and the processed image is displayed through a displaying and warning module. The early warning method of overloading of the tourist footbridge in the scenic area is low in cost and high in reliability.

Description

technical field [0001] The invention relates to the technical field of computer vision monitoring, in particular to the number monitoring and overcrowding early warning for tourist pedestrian bridges in scenic spots. Background technique [0002] The pedestrian bridge for tourists in the scenic area is a very common tourist attraction in the scenic area, but there is a safety hazard of overcrowding. At present, the existing methods of people monitoring or early warning mainly adopt the design of digital devices at the entrance and exit, such as devices such as foot sensors, gates or infrared sensors, but these devices are prone to natural erosion such as wind and rain outdoors, thus Make the device ineffective, in addition tourists usually come in groups, these devices will also interfere with tourists. [0003] The estimation of the number of people is a relatively mature method in the field of computer vision. The present invention introduces the estimation of the number ...
