Problems solved by technology

[0006] The disadvantage of the above-mentioned prior art is that the existing level requires at least two people to complete the measurement, one of whom is responsible for the steering, aiming and focusing of the level, and the other is responsible for moving the leveling rod from one point to another

Abstract

The invention relates to a digital level capable of automatically tracking a level rod and automatically completing measurement, comprising a wide-angle camera processing system, a telescope focusing system, a CCD device and a CPU unit, wherein the wide-angle camera processing system is used for finding a scale in all around under the driving of a horizontal rotating base, and then calculating the orientation and distance of the scale; the telescope focusing system is used for adjusting the direction thereof to automatically focus after aligning the scale according to the orientation and distance of the scale; the CCD device is used for acquiring precise images of the scale by the telescope focusing system after focusing; and the CPU unit is used for controlling the horizontal rotating base to rotate by a corresponding angle according to the orientation and distance of the scale so as to lead the telescope focusing system to align the scale, then driving the telescopic focusing systemto corresponding focal distance, acquiring the image forming the scale in the CCD device, finally calculating the height and distance of the scale and storing the height and distance in a memory.

Description

technical field [0001] The invention relates to a digital level for automatic measurement, in particular to a digital level capable of automatically tracking a leveling rod and automatically completing measurement. Background technique [0002] The basic principle of leveling is to use the horizontal line of sight of the level to collide with the readings of the leveling rod vertically erected on two points to measure the height difference between the two points. [0003] There are two methods of leveling: optical leveling and digital leveling. [0004] Optical leveling is currently the most widely used leveling method that can meet various levels. Optical levels and leveling rods are used for measurement. The optical level is mainly composed of a telescope, a reticle, a bubble level, a casing and a base. The telescope is composed of an objective lens, a focusing lens, and an eyepiece. The automatic leveling level is also equipped with an automatic leveling device. Three h...
