Abstract

The invention discloses a construction safety judgment method based on binocular vision. The construction safety judgment method comprises the steps: collecting a sample picture of a construction site, and manually marking the position coordinates of a constructor and a crane in the sample picture; training a constructor detection and crane detection model by adopting a deep convolutional neural network; obtaining binocular camera parameters; a binocular video frame of a construction site is acquired in real time through a binocular camera; detecting the position coordinates of the constructorand the position coordinates of the crane in the binocular video frame by using the constructor detection and crane detection model; when x2 + w2 is smaller than x1 and x1 + w1 is smaller than x2, conducting stereo matching on the constructor and the crane detected in the binocular video frame, and obtaining the depth value z1 of the constructor and the depth value z2 of the crane; and when the absolute value of z1-z2 is smaller than the epsilon, considering that the constructor is located below the crane and belongs to dangerous construction behaviors. According to the invention, 24-hour all-weather dangerous behavior detection of constructors can be realized, so that safety supervision of a construction site is realized, and the construction efficiency and safety are improved.

Description

technical field [0001] The invention relates to the field of safe construction, in particular to a method for judging construction safety based on binocular vision. Background technique [0002] Safe construction is the top priority in electric power construction, and it is very important to take safety measures for on-site construction. Irregular behavior of construction workers is one of the main factors that generate construction safety risks. For example, the dangerous behavior of construction workers standing under construction cranes in violation of regulations is a factor that generates construction safety risks. The safety management of existing electric power construction mainly relies on human supervision, which is easy to cause regulatory loopholes, cannot realize the safety supervision of construction threads, affects construction efficiency, and has safety problems. Contents of the invention [0003] The technical problem to be solved by the present invention...
