Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0019] A high-efficiency laser mapping method based on municipal engineering, comprising the following steps:

[0020] S1. Check the laser measuring instrument to ensure that the laser measuring instrument is in normal working condition, and fix the laser measuring instrument on the tripod. The tripod is made of wooden tripod, which is light in weight and easy to carry, and can reduce vibration at the same time. Accuracy, and then determine the origin of the coordinates. When selecting the origin of the coordinates, ensure that the origin is selected in a place with a wide field of vision, an open surrounding environment, and a high terrain. , under the shade of trees and near water,...

Abstract

The invention relates to the technical field of municipal engineering, in particular to a high-efficiency laser mapping method based on municipal engineering. The method comprises the following steps:S1, a laser measuring instrument is checked to ensure that the laser measuring instrument is in a normal working state, the laser measuring instrument is fixed on a tripod, and the origin of coordinates is then determined; S2, the laser measuring instrument is placed at the origin, the horizontal direction of the tripod is leveled, and the laser measuring instrument is ensured to be in a horizontal state; S4, the data of the laser measuring instrument are transmitted wirelessly, the data are imported into a data processor, the data are processed by the data processor, the data are imported into a computer by USB, and image drawing is carried out; and S5, after image drawing, the drawing is printed by a printer. The measurement accuracy is ensured, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to an efficient laser surveying and mapping method based on municipal engineering. Background technique [0002] Various orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry instruments used in the planning and design, construction and operation management stages of the project construction are generally used for data collection by laser measuring instruments. For measurement, there are many instruments of this type, and the common point is to connect a helium-neon laser to the telescope, guide the laser beam into the telescope tube, and make it coincide with the collimation axis. Using the advantages of good directivity of the laser beam, small emission angle, high brightness, and visible red, a sharp collimation line is formed as the basis for orientation and positioning. Then draw, the existing surveying and mapping m...
