A hoisting safety distance detection method based on deep learning

Abstract

The invention discloses a hoisting safe distance detection method based on deep learning. The hoisting safe distance detection method based on deep learning includes the steps that the image around ahoisting hook in a tower crane structure is obtained through a camera; a worker and the hoisting hook in the image are marked, and a data set are made; the data set is trained through Faster R-CNN indeep learning; the worker and the hoisting hook in the image are recognized and positioned through a trained detection model; the pixel distance between the worker and the hoisting hook is worked outaccording to positioning information in the detection result; and the pixel distance between the worker and the hoisting hook is converted into the actual distance between the worker and the verticalprojection point of the hoisting hook according to the height of the hoisting hook and the camera and the actual length and pixel length of the hoisting hook, and then detection of the hoisting safe distance is realized. By means of the hoisting safe distance detection method based on deep learning, recognition and positioning problems of the worker and the hoisting hook in the image are effectively solved, and high accuracy is achieved on the aspect of safe distance detection.

Description

technical field [0001] The invention belongs to the field of safety monitoring of civil engineering construction machinery, and relates to a method for detecting a safety distance between a worker and a hook during the hoisting process of a tower crane. More precisely, the present invention relates to a method that can identify and locate the worker and the hook in the image through a deep learning algorithm during the hoisting process, and realize the detection of the safe distance between the worker and the hook according to the positioning information and the conversion method. . Background technique [0002] With the continuous increase of urban population, the demand for high-rise and super high-rise buildings is increasing. In order to improve construction mechanization and industrialization, tower cranes are widely used in the construction process of high-rise and super high-rise buildings. The objects hoisted by the tower crane have high potential energy, wide opera...

Problems solved by technology

However, it is impossible to judge the actual distance between the worker and the hook, and it is impossible to quantitatively detect the safe distance of hoisting, but this distance is crucial to the safety of hoisting
