Quick measuring method based on laser ranging device

Abstract

The invention discloses a quick measuring method based on a laser ranging device. The quick measuring method comprises the following steps of: 1, selecting a standing point, that is to say, selecting an observation point, which is beneficial for observation of a GPS (Global Positioning System), as a standing point P1 of a measuring worker; 2, measuring geographical coordinates of the standing point, that is to say, measuring geographical coordinates P1 (B1, L1) of the standing point P1 by utilizing a GPS measuring device; 3, measuring by the laser ranging device, that is to say, measuring horizontal distances s among a true azimuth angle A12 of a straight line of the standing point P1 and a point to be measured P2, the standing point P1 and the point to be measured P2 by utilizing the laser ranging device, wherein the laser ranging device is a laser ranging device provided with an electronic compass; and 4, converting the geographical coordinates of the point to be measured P2. The quick measuring method, provided by the invention, has the advantages of simple operation, convenience for implementation, quick measuring speed, high measuring precision, and capability of really realizing quick and accurate measurement of a detail point, and effectively solving the problems of slow measuring sped and difficulty in measurement of the conventional handheld GPS measuring method.

Description

technical field [0001] The invention relates to a quick measurement method for geographic information, in particular to a quick measurement method based on a laser rangefinder. Background technique [0002] The laser range finder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. 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. Nowadays, there are many laser range finders with built-in electronic compass on the market, that is to say, this type of laser range finder has its own electronic compass. [0003] GPS i...
