Abstract

The invention discloses a point cloud quality evaluation method and device. The point cloud quality evaluation method comprises the steps of S1, acquiring the point cloud signal-to-noise ratio, the point cloud density, the point cloud thickness and the point cloud overlap, respectively comparing the point cloud signal-to-noise ratio, the point cloud density, the point cloud thickness and the pointcloud overlap with preset scoring standards, and acquiring a score of the point cloud signal-to-noise ratio, a score of the point cloud density, a score of the point cloud thickness and a score of the point cloud overlap; and S2, respectively multiplying the score of the point cloud signal-to-noise ratio, the score of the point cloud density, the score of the point cloud thickness and the score of the point cloud overlap by a preset weight and performing the summation to obtain an evaluation value of the point cloud quality, and comparing the evaluation value of the point cloud quality with apreset point cloud quality evaluation standard to obtain evaluation for the point cloud quality. According to the point cloud quality evaluation method, the point cloud signal-to-noise ratio, the point cloud density, the point cloud thickness and the point cloud overlap are taken into evaluation indexes for the point cloud quality, thereby being capable of comprehensively evaluating the point cloud quality, and solving a technical problem that the point cloud quality cannot be effectively evaluated at present.

Description

technical field

[0001] The invention relates to the field of data analysis, in particular to a point cloud quality evaluation method and device. Background technique

[0002] As a new type of spatial data acquisition technology, airborne lidar measurement technology has the advantages of high degree of automation, low weather influence and high precision. It is currently widely used in many fields such as terrain surveying and mapping, environmental monitoring and forestry management.

[0003] However, the current airborne lidar measurement has no corresponding technical specifications and operating standards, and it is difficult to effectively evaluate the point cloud quality in airborne lidar technology. Therefore, it leads to technical problems that currently cannot effectively evaluate the point cloud quality. Contents of the invention

[0004] The invention provides a point cloud quality evaluation method and device, which solves the current technical problem that th...
