Distance meter for measuring distance between two target points

Abstract

The invention discloses a distance meter for measuring the distance between two target points, comprising a first laser, a second laser, an image sensor, a numeric operation module and a display screens, wherein the first laser emits a laser beam to a first target point and the second laser emits a laser beam to a second target point, thereby obtaining a first emission angle and a second emission angle; the image sensor is used for receiving reflected laser beams of the first target point and the second target point and sending the first image information and the second image information formed by the reflected laser beams to the numeric operation module; and the numeric operation module is used for obtaining distance data between the first target point and the second target point and sending the distance data to the display screen for displaying. The invention provides a brand new distance measuring mode which can conveniently and effectively measure the distance between each pair of points. When in use, the first laser fixedly points to the target points, and the second laser is manually adjusted to align with the target points, thus a user can use the distace meter by hands.

Description

technical field [0001] The invention relates to a distance measuring technology, in particular to a distance measuring instrument for measuring the distance between two target points. Background technique [0002] The laser range finder is light in weight, small in size, easy to operate, fast and accurate, and its error is only one-fifth to several hundredths of other optical range finders, so it is widely used in terrain measurement, battlefield measurement, tank , Aircraft, ships and artillery to target range measurement, measuring the altitude of clouds, aircraft, missiles and artificial satellites, etc. At the same time, it is also an important technical equipment to improve the accuracy of high tanks, aircraft, ships and artillery. [0003] The laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. Existing laser range finder emits a very thin laser beam to the target when it is working, the photoelectric element receives ...
