Construction alert area monitoring and early warning system and method based on image recognition

Abstract

The invention provides a construction alert area monitoring and early warning system and method based on image recognition. The system comprises an image input module, an image splicing module, an interactive calibration module, a pedestrian detection module, a visual intrusion module, a feature extraction module, and a decision module. The visual intrusion detection, target detection and re-recognition techniques are combined, and cameras are arranged around a construction alert area or dangerous construction equipment to acquire surrounding environment information and in-out person information in real time, so that an operator can replace an early warning trigger area and operator registration information at any time, and whether a person invasion signal exists in the early warning trigger area or not is updated in real time; and when the person invasion signal exists, activation is carried out, an alarm is given to remind violation personnel to forbid entering the area, and the safety of the construction alert area is guaranteed.

Description

technical field [0001] The invention relates to the technical field of information monitoring and early warning, in particular to a monitoring and early warning system and method for construction warning areas based on image recognition. Background technique [0002] In the engineering construction area, such as hoisting operations (including bridge erecting machine tower cranes), mechanical operations, hydraulic sliding formwork, blasting operations, main tower construction, silo wall periphery, and tensioning operations required by national and industry standards or guidelines The area where the warning zone is set, and the area where the construction warning zone should be set up under the high-level operations such as hanging baskets and mobile formwork construction, usually barbed wire fences are set up to prevent unrelated technical personnel from entering the construction area and prevent unsafe incidents. However, for a large-scale construction area, directly setting...

Problems solved by technology

However, for a large-scale construction area, directly setting up fences will not only affect the entry and exit of construction personnel, but also cause missed inspections.

At the same time, due to the large construction area and the progress of the project, the construction area needs to change, and the use of barbed wire fences will cause waste of resources and manpower. Therefore, it is necessary to find a safer, more effective and convenient monitoring and early warning method
