Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping equipment, in particular to an area measuring device based on laser surveying and mapping. Background Art

[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to accurately measure the distance to a target. A pulsed laser rangefinder emits a beam or a series of short pulsed laser beams to a target during operation. The laser beam reflected by the target is received by a photoelectric element. A timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the rangefinder to the target. When using a laser rangefinder to calculate an area, it is usually necessary to first use the laser rangefinder to measure the length of the object, and then rotate 90 degrees at the same point to measure the width, and calculate the measured area.

[0003] According to the "Area measurement device based on laser mapping" provided by China Patent Authorization Announcement No. CN213748305U, the laser rangefinder is limited by pulling out and pulling in the plug at the fixed plate, which facilitates the measurement of the wall area. However, the multiple insertion and removal of the plug can easily lead to its loss, which affects the area calculation of the laser rangefinder to a certain extent and increases the cost to a certain extent.

[0004] Therefore, an area measurement device based on laser mapping is designed to solve the above problems. Utility Model Content

[0012] Compared with the related art, the area measurement device based on laser mapping provided by the utility model has the following beneficial effects:

[0013] The utility model provides an area measuring device based on laser surveying and mapping. The counterweight ring and the laser rangefinder are arranged to facilitate the measurement of the height of the wall. The rotating cap and the rotating column are arranged to drive the rotating disk to rotate ninety degrees with the rotating rod as the central axis. The pressing plate arranged in cooperation with the pressing drives the pressing plate to swing with the supporting rod as the central axis, so that the plug-in plate and the slot are plugged in each other.
