Description
Technical field
The invention belongs to survey field, be specifically related to a kind of laser mapping method based on municipal works mapping.
Background technology
Mapping is based on computer technology, photoelectric technology, network communications technology, space science, information science, with GPS (GPS), remote sensing (RS), Geographic Information System (GIS) for technological core, existing for ground unique point and boundary line are obtained figure and the positional information of reflection ground present situation by measurement means, for the planning and design of engineering construction and administration.
Existing mapping method is for using the large area mapping of big payload helicopter high-altitude, it needs a large amount of photo large area forward image to superpose, Survey and map software is used to carry out a large amount of later stage correction, in order to obtain each buildings or structures and surface configuration change foundation point coordinate point in mapping region, also need to carry out a large amount of on-the-spot tune to paint, this kind of method precision is low, costly, and complicated operation.
Summary of the invention
The object of this invention is to provide a kind of laser mapping method based on municipal works mapping, the method precision is high, and later stage expense is low, simple to operate, and efficiency is high.
Based on a laser mapping method for municipal works mapping, comprise the following steps
A. multiple discrete check point is set in mapping region, and obtains check point coordinate;
B. placing laser range finder and mapping processor on mapping ground, is that initial point carries out laser mapping with check point; Laser range finder and mapping processor are operated in mapping state, and the signal that surrounding enviroment are formed is sent to mapping processor place by laser range finder, carries out picture drafting;
C. the side direction buildings or structures and surface configuration change foundation point image of drawing picture are got;
D. obtain picture images in individual step c, in conjunction with check point coordinate reference, resolve, obtain buildings or structures and surface configuration change foundation point coordinate point;
E. will survey and draw multiple continuum images in region and repeat steps d method, and obtain each buildings or structures and surface configuration change foundation point coordinate point in mapping region, acquisition coordinate points will be spliced.
The working method of described laser range finder and mapping processor be the laser beam that sends of laser range finder after rotating mirror with the rotating mirror anglec of rotation to mapping ground polishing, the laser polishing point on mapping ground produces scattering or reflected light, with same angle to laser range finder backspace, received by laser range finder, the distance signal of process that laser range finder receives, the rotation angle chrominance signal of rotating mirror send the process of mapping processor.
Described check point is the obvious sign with GPS arranged on the ground.
It is the observation landform looks of reference point that described mapping processor the most directly provides with check point when drawing ground elevation distribution.
Compared with prior art, the present invention has following beneficial effect:
Because the present invention adopts laser to draw the method for side direction buildings or structures and surface configuration change foundation point image, get aerial photograph side direction buildings or structures and surface configuration from traditional to change forward image mapping method completely different, again by obtaining drafting image in individual step c, in conjunction with check point coordinate reference, resolve, obtain buildings or structures and surface configuration change foundation point coordinate point, multiple continuum image repeated resolution in region will be surveyed and drawn, and obtain each buildings or structures and surface configuration change foundation point coordinate point in mapping region, acquisition coordinate points is spliced.Thus each buildings or structures obtained in whole mapping region and surface configuration change foundation point coordinate point, later stage carries out the correction of a large amount of photo large area superposition without the need to a large amount of software, adjust without the need to scene and paint, and disposablely obtain each buildings or structures and surface configuration change foundation point coordinate point by single photo, again by the splicing of coordinate points, mapping precision is high, and later stage expense is low, simple to operate, efficiency is high.
