Embodiment 1

[0045] This embodiment provides a scanning system including a scanning device and a processing module, which may be an intelligent terminal, a server side, or a processor that scanned device itself.

[0046] In the present embodiment, the scanning device is a laser radar, and the scanning device may also be a 3D scanner (such as a sweeping robot), and the scanning means includes the processing module.

[0047] In other embodiments, the processing module is a smart terminal or server.

[0048] The processing module is for:

[0049] Get a two-dimensional plan;

[0050] The two-dimensional appended part is divided into several closed areas;

[0051] The closed area is a polygon that represents a line that represents a line structure.

[0052] Find the concave polygon in the closed area, divide each concave polygon into a closed area of ​​a plurality of convex polygons;

[0053]For each convex polygonal closed area, the site of the closed area is obtained according to the scanning par...

Embodiment 2

[0110] The present embodiment is substantially the same as that of Example 2, and the difference is only:

[0111] The processing module is for:

[0112] Get together according to the scan parameters;

[0113] The center of the concentric circle is placed in the center of gravity of the closed area as the simulated scan;

[0114] It is judged that the number of the closed area is in the consensus circle whether or not the ratio of the closed area edge length reaches the predetermined ratio, if it is the center of gravity as the site, if otherwise, the closed area is separated at the center of gravity. .

[0115] Accordingly, the scanning parameters include maximum scanning distance and shortest scanning distance, the site acquisition method comprising:

[0116] Get together according to the scan parameters;

[0117] The center of the concentric circle is placed in the center of gravity of the closed area as the simulated scan;

[0118] It is judged that the number of the closed ar...

Abstract

The invention discloses a site acquisition method, a scanning device and a system for actual measurement, and relates to the technical field of the site acquisition method, the scanning device and the system for actual measurement, and the site acquisition method comprises the following steps: acquiring a two-dimensional house type image; dividing the two-dimensional house type image into a plurality of closed areas; searching concave polygons in the closed areas, and dividing each concave polygon into closed areas of a plurality of convex polygons; for the closed area of each convex polygon, the site of the closed area is obtained according to scanning parameters of a scanning device and the size of the closed area, and the site is the scanning position of the scanning device in the corresponding actual site of the two-dimensional house type image; and obtaining the position of the station corresponding to the two-dimensional house type image. According to the method, the recommended scanning site of the site corresponding to the building house type image can be obtained by analyzing the building house type image, user operation and use are facilitated, the working efficiency is improved, and the imaging effect of the obtained scanning data can be better.

Description

Technical field [0001] The present invention relates to a site acquisition method, a scanning device, and a system for actually measurement. Background technique [0002] 3D laser scanners suitable for indoor environmental scanning TOF (TIGH-FLight) ranging technology, which is most commonly used to LIDAR (Light Detection and Ranging). It is an optical remote sensing technique for calculating an object distance by measuring the time difference of the pulse signal transmitted and received. Its advantage is that the accuracy is high, far from the distance; but it is also limited to the physical trays of all light, such as Lidar is difficult to measure the distance from the sensor to the window (light through the glass), the Lidar cannot scan the structure behind the wall (Light along linearly), etc. In addition, the accuracy of the LIDAR is also affected by the material of the subject, the distance between the scanner and the incident angle. [0003] 3D laser scanners suitable for ...
