Embodiment 1

[0052] see figure 2 , image 3 and Figure 4 , this embodiment provides an image processing system, the laser scanning system includes a laser scanner and a processing terminal.

[0053] The laser scanner is used to obtain three-dimensional scanning data of a building area, and obtain a two-dimensional floor plan according to the three-dimensional scanning data;

[0054] The processing terminal is used to transform the vector of the two-dimensional floor plan to match the transformed two-dimensional floor plan with the design map of the building area;

[0055] The processing terminal is also used to acquire the overlapping amount between the converted two-dimensional house type drawing 11 and the design drawing 12 .

[0056] Further, the processing terminal is also used for:

[0057]Carry out segmentation and semantic recognition on the 3D scanning data to obtain several components with semantic information, and then obtain the components of the 2D floor plan correspondin...

Abstract

The invention discloses an image processing method and system for actual measurement and a laser scanner, and the method comprises the steps: obtaining the three-dimensional scanning data of a building area, and obtaining a two-dimensional house type image according to the three-dimensional scanning data; transforming a vector of the two-dimensional house type drawing to match the transformed two-dimensional house type drawing with a design drawing of the building area; and obtaining the coincidence amount of the transformed two-dimensional house type drawing and the design drawing. According to the image processing method and system for actual measurement and the laser scanner, the actual measurement can be accurately matched with the situation that the difference between the actual measurement and the design drawing is large, the difference between the actual measurement data and the design drawing is obtained, modification items in actual engineering are rapidly obtained, and construction acceptance and user use are facilitated.

Description

technical field [0001] The invention relates to an image processing method, system and laser scanner for actual measurement and measurement. Background technique [0002] The so-called actual measurement and measurement refers to a method that can truly reflect product quality data through on-site testing and measurement using measurement tools. According to the relevant quality acceptance standards, the quality data error of the measurement control project is within the allowable range of the national housing construction standards. [0003] In order to strengthen the quality management of housing construction, improve the awareness of quality responsibility, strengthen the investigation of quality responsibility, and ensure the quality of project construction, on August 25, 2014, the Ministry of Housing and Urban-Rural Development issued the "Provisional Measures for the Quality Lifetime Responsibility of the Person in Charge of the Five Party Responsibilities of Construct...
