Abstract

The invention provides a distance-measuring device which is used for measuring a distance U between a first object and a second object. The distance-measuring device comprises a light-emitting sphere, a prime lens, an image photosensitive element and a processing module, wherein the light-emitting sphere is mounted on the first object; the prime lens is mounted on the second object; the image photosensitive element is arranged in the rear of the prime lens and acquires an image formed by the light-emitting sphere passing through the prime lens; and the processing module is connected with the image photosensitive element and acquires the diameter of the image and calculates the distance U between the first object and the second object according to the following fomula: U=f(D+d) / d, wherein f is the focal distance of the prime lens, and D is the diameter of the light-emitting sphere. The distance-measuring device provided by the invention is simple in structure and high in distance-measuring speed.

Description

[0001] 【Technical field】 [0002] The invention relates to a distance measuring device, in particular to a distance measuring device with simple structure and fast distance measuring speed. 【Background technique】 [0003] The existing target distance measurement is realized by calculating the time and speed of related auxiliary equipment (such as laser range finder), and the characteristics of the optical lens itself are not well utilized to achieve target distance measurement. The parameters of the optical lens itself are determined by mathematics Calculation is able to calculate the distance of the lens currently observing the target. [0004] The image measuring instrument is the fastest-growing geometric optical measuring instrument in the past ten years. It is based on the principle of optical projection, combined with the application of modern photoelectric technology and computer processing technology, to achieve the measurement of length and dimension by aiming at th...
