Embodiment Construction

[0055] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0056] According to the attached figure 1 , The present invention is a method for quickly recognizing the unloading soil of vehicles in a subway protection area, which includes a video image and ultrasonic data acquisition system in the monitoring area of ​​the subway protection area, and also includes the following steps S1 to S6:

[0057] S1. Boundary image delineation of subway protection area, image pixel resolution calibration and basic terrain elevation data scanning.

[0058] The specific operation of the step S1 is as follows:

[0059] (1) When the monitoring site is installed, it is based on video images, such as figure 2 As shown, the actual boundary of the subway protection area is manually delineated by using multiple line segments, and the protected area and the non-protected area are marked as with , To store the image boundary and area data, as the...

Abstract

The invention relates to a rapid identification method for unloading and soil piling of vehicles in a protection area. The method mainly solves the technical problems that vehicle unloading and soil piling in ground protection areas of existing tunnels, foundation pits and other underground engineering are not supervised in time and intelligent and the like. According to the technical scheme of the invention, the method comprises a video image and ultrasonic data collection system in a protection area monitoring area, and also comprises the steps: S1, protection area boundary image demarcation, image pixel resolution calibration and basic terrain elevation data scanning; s2, based on the video image, dynamically monitoring a moving object in the area through an image edge detection algorithm, and carrying out primary judgment on the large vehicle; s3, residence time of the large vehicle in the protection area is calculated, and the vehicle type is recognized; s4, vehicle unloading soilpiling three-dimensional reconstruction and volume remote non-contact measurement are carried out; s5, vehicle unloading and soil piling warning information is sent; and S6, repeating the step S1, the step S3, the step S2, the step S3, the step S4 and the step S5 to realize continuous monitoring of unloading and soil piling of the vehicles in the protection area.

Description

Technical field [0001] The invention relates to a rapid identification method for vehicle unloading piled soil, in particular to a rapid identification method for illegally unloading piled soil for vehicles in ground protection zones of underground projects such as tunnels and foundation pits, and is applied to the field of protection zone safety monitoring. Background technique [0002] With the rapid development of urbanization, there are more and more underground projects such as tunnels and foundation pits. As the project is located in the urban area, its safety becomes more and more important. In particular, the subway has become an important part of urban transportation because of its large transportation volume, land saving, environmental protection and energy saving, and it has played an increasingly important role. According to the CJJT 202-2013 "Technical Specification for the Safety Protection of Urban Rail Transit Structures" of the Ministry of Housing and Urban-Rural...
