Distance measurement method, device and electronic device

Abstract

The present invention belongs to the image distance measurement technological field and relates to a distance measurement method, a distance measurement device, and an electronic device. According tothe distance measurement method, the distance measurement device, and the electronic device of the invention, an image which is shot by a distance measurement image pickup device and contains a distance measurement target, and a horizontal distance from the distance measurement target to the center position of the image are acquired; the horizontal size of the image and the visual angle of the distance measurement image pickup device are acquired; a distance measurement angle is obtained according to the visual angle, the horizontal distance and the horizontal size; a vertical distance from the distance measurement target to the center position of the image and the pixel height of the vertical distance in a light sensing element are acquired; the vertical size of the light sensing elementin a vertical direction and vertical pixel size corresponding to the vertical size are acquired; a light sensing distance from the light sensing element to an image pickup lens is obtained; the product of the vertical pixel size, the light sensing distance and the vertical distance is solved, and is divided by the pixel height, the vertical size and the cosine value of the distance measurement angle, so that a distance from the distance measurement image pickup device to the distance measurement target can be obtained. With the method adopted, distances can be measured 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.
