Abstract

The invention discloses a measurement device based on laser distance measurement and a measurement method thereof. The measurement device comprises a camera, a base for placing the camera, a laser base and a laser head. The length and the height value of an object to be measured can be calculated by locking an animal or a building at a distance through laser, leaving laser spots on a picture, calculating the ratio of the distance between practical laser heads to the distance between corresponding laser spots on the picture and obtaining the proportion of a real object to the object in the picture. According to the device and the method disclosed by the invention, the structure is simple; the method is not influenced by the size and the distance of the object to be measured; the calculation process is convenient; in particular, the method is convenient and rapid for a movable and large-area object to be measured; and the working efficiency is greatly increased.

Description

technical field [0001] The invention relates to the technical field of laser ranging, in particular to a measuring device based on laser ranging and a measuring method thereof. Background technique [0002] When wildlife scientists conduct research on wild animals, in addition to fully understanding the habits of wild animals, sometimes they need to know the shape and size of wild animals for further research. Some distance measuring methods in our daily life cannot measure animals in motion, and a method for measuring the length and height of animals at a long distance is needed. [0003] With the development of optical technology, people have more and more research on optical characteristics, and optical technology has also been applied to various fields. A typical application is to use optical features to measure distance. The laser has the characteristics of high brightness, high directivity, high monochromaticity and high coherence, which greatly improves the measurem...
