Camera visual object height measurement method and device and computer readable storage medium

Abstract

The invention discloses a method for measuring the height of a visual object of a camera. The method comprises the following steps: acquiring an image of a to-be-measured building; performing edge extraction and angular point detection on the image of the to-be-detected building by using a pre-trained detection model to obtain an angular point of the to-be-detected building and an angular point of a scale; calculating a first height of the scale in the image of the building to be measured according to the angular point of the scale; calculating a second height of the to-be-measured building in the image of the to-be-measured building according to the angular point of the to-be-measured building; and calculating the height of the to-be-measured building based on the first height, the second height, the actual height of the scale and a correction factor. According to the invention, on the basis of industrial pains of traditional manual inspection and inspection of house building area, building height measurement algorithm key technology research based on artificial intelligence is carried out, building construction height progress is accurately mastered, digital and intelligent supervision transformation is realized, the supervision efficiency of a real estate transaction center is improved, human resources are saved, and the operation cost is effectively reduced.

Description

technical field [0001] The invention relates to the field of visual detection, in particular to a method and device for measuring the height of a camera visual object and a computer-readable storage medium. Background technique [0002] One of the traditional object height measurement methods is the binocular matching method. Through the principle of triangulation, the difference between the abscissas of the target point in the left and right views (parallax Disparity) is inversely proportional to the distance from the target point to the imaging plane. relationship to obtain in-depth information. The second method is the structured light method. The basic principle is to project a pre-designed pattern as a reference image (coded light source), project the structured light onto the surface of the object, and then use the camera to receive the structured light pattern reflected by the surface of the object. In this way, Two images are also obtained, one is a pre-designed ref...

Problems solved by technology

However, the traditional triangulation ranging method either requires the parameters of the camera, or requires complex functions, or requires strict calculation methods.
