Abstract

The invention relates to the technical field of image ranging, in particular to a ranging method, device and electronic equipment. By obtaining the image of the ranging target captured by the ranging camera device and the horizontal distance from the ranging target to the center of the image, the horizontal size of the image and the viewing angle of the ranging camera device are obtained, according to the viewing angle, horizontal distance and horizontal size Obtain the ranging angle; obtain the vertical distance from the ranging target to the center of the image and the pixel height of the vertical distance in the photosensitive element, obtain the vertical size of the photosensitive element in the vertical direction and the vertical pixel size corresponding to the vertical size, and obtain the vertical distance from the photosensitive element to the camera For the photosensitive distance of the lens, calculate the product of the vertical pixel size, photosensitive distance and vertical distance, and divide the product by the cosine value of the pixel height, vertical size and distance measurement angle to obtain the distance from the distance measurement camera device to the distance measurement target. This method can measure distance quickly.

Description

technical field [0001] The present invention relates to the technical field of image distance measurement, in particular, to a distance measurement method, device and electronic equipment. Background technique [0002] With the development of society, distance measurement technology continues to develop. Distance measurement has changed from the most primitive estimation to measuring tool measurement to today's high-tech measuring instruments. At this stage, image-based ranging methods and laser ranging methods are more popular. Image-based ranging methods include ranging methods based on depth cameras and ranging methods based on binocular cameras. Using sensors or cameras to measure distances is costly, computationally intensive, and complex to operate. Contents of the invention [0003] The purpose of the present invention is to provide a ranging method, device and electronic equipment, which aims to improve the above-mentioned problems existing in the prior art.
