Embodiment 1

[0036] A method for analog surveying and mapping based on municipal engineering, comprising the steps of:

[0037] (1) According to the azimuth, distance, and elevation of the existing buildings, the laser beam emitted by the laser rangefinder is used to illuminate the surveying and mapping ground at the rotation angle of the rotating mirror after passing through the rotating mirror, and the laser lighting point on the surveying and mapping ground Generate scattered or reflected light, return to the laser rangefinder at the same angle, and be received by the laser rangefinder. The processing distance signal received by the laser rangefinder and the rotation role signal of the rotating mirror are sent to the surveying and mapping processor for processing;

[0038] (2) Use a repair agent to wash the section defects at high pressure, and then pre-set a number of different points in the section area, select discrete preset points, spread all over the lowest point, the highest point...

Abstract

The invention discloses a simulation surveying and mapping method based on municipal engineering, wherein the method is applied to the field of surveying and mapping. Therefore, a technical problem ofinaccurate pavement testing with cross-section defects can be solved. The method comprises the following steps: step one, carrying out field measurement; step two, drawing a picture of the section area; step three, carrying out measurement on a piece of computing paper; step four, simulating a reference plane; and step five, acquiring a three-dimensional model; to be specific, collecting a streetpicture near a defective road surface, drawing the dimension of the road defect on the computing paper, determining the actual reference plane, carrying out enlargement corresponding based on a measuring scale, and simulating real conditions of the building and road in a surveying and mapping area to obtain a three-dimensional model finally. According to the disclosed method, road defect measurement is carried out on the computing paper and the actual reference plane is simulated, so that the accuracy of the surveying and mapping work is improved. The operation becomes simple and convenient and the test results are closer to the actual conditions.

Description

technical field [0001] The invention relates to municipal engineering, in particular to a simulation surveying and mapping method based on municipal engineering. Background technique [0002] Surveying and mapping is based on computer technology, photoelectric technology, network communication technology, space science, and information science, with the global positioning system (GPS), remote sensing (RS), and geographic information system (GIS) as the technical core, and the existing characteristics of the ground Points and boundaries obtain graphics and position information reflecting the current status of the ground through measurement means, which are used for planning, design and administrative management of engineering construction. [0003] With the development of cities, the requirements for road surveying and mapping are getting higher and higher. Only high-quality engineering surveys can make municipal engineering fully play its due roles and functions. At present...
