Display method for actual measurement, measurement system and laser radar

Abstract

The invention discloses a display method for actual measurement, a measurement system and a laser radar. The display method comprises the following steps of scanning a wall body to obtain three-dimensional data points of the wall body; analyzing principal components of the three-dimensional data points to obtain a plane area in the three-dimensional data points as a zero plane; dividing the three-dimensional data points into a plurality of data point areas; obtaining the distance from the target area to the zero plane; and displaying the image corresponding to the data point area in the zero plane in the position corresponding to the zero plane in a display interface in the basic color, and displaying the image corresponding to the target area in the position corresponding to the target area in the display interface in the preset color. According to the display method, the measurement system and the laser radar, flatness of the wall can be visually and detailedly displayed, the informatization degree of the building industry is improved, convenience is provided for acceptance check and wall rectification of a user, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to a display method for actual measurement, a measurement system and a laser radar. Background technique [0002] The so-called actual 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] The project development stages involved in the actual measurement mainly include the main structure stage, masonry stage, plastering stage, equipment installation stage and fine decoration stage. The measurement scope includes concrete structure, masonry project, plastering project, waterproof project, door and window project, painting project, fine decoration project, etc. [0004] The existing measurement tools are low in efficiency and single in function, mak...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defects of low efficiency, single function and inconvenient viewing of the existing measuring and measuring tools in the prior art, and to provide a method that can intuitively and detailedly display the flatness of the wall and improve the building quality. The degree of informatization in the industry provides convenience for users to check and accept, rectify the wall, and speed up the construction progress. The display method, measurement system and laser radar for actual measurement and measurement
