Embodiment 1

[0030] see Figure 1-3 , a handheld concrete roughness three-dimensional detection device, which includes a camera mounting plate 8, the bottom end of the camera mounting plate 8 is symmetrically fixed with a first camera assembly 9 and a second camera assembly 11, the first camera assembly The laser 10 for positioning is fixed at the position between the camera 9 and the second camera assembly 11, and the camera mounting plate 8 is connected with the hand-held structure through the connecting plate 4; it also includes a calibration plate 12 for positioning the scanning position, the calibration plate 12 cooperates with the first camera assembly 9, the second camera assembly 11 and the laser 10, and realizes the three-dimensional scanning of the concrete surface of the set area. The detection device using the above structure can be used for the roughness detection of the concrete surface. It obtains the three-dimensional point cloud data of the concrete surface, and obtains it...

Embodiment 2

[0036] A method for concrete roughness detection by a handheld concrete roughness three-dimensional detection device, which includes the following steps:

[0037] Step 1: clean up the sundries on the concrete surface to be detected, and select a suitable detection area, place the calibration plate 12 in the selected area, place it flat and fix the calibration plate 12 in the area;

[0038] Step 2: Hold the handle 1, and scan the rectangular area 14 of the calibration plate 12 by moving the above-mentioned detection device to obtain the three-dimensional point cloud data of the concrete surface;

[0039] Step 3: According to the three-dimensional point cloud data, the calculation method of the plane expansion rate is used to calculate the roughness of the point cloud data.

[0040] In the scanning process used in the second step, the point cloud data is acquired by a single-panel scanning method, or the point cloud data is acquired by using the mark points 13 in the calibration...

Abstract

The invention provides a three -dimensional detection device and method of handheld concrete roughness, which includes the camera installation board, the bottom end of the camera installation board faces the first camera component and the second camera component of the fixed installation. The first camera is the first camera.The position between the component and the second camera component is fixed for a laser that is used for positioning, which is connected to the handheld structure through the connecting board; it also includes the calibration board used to locate the scan position.The second camera component and laser are matched, and the three -dimensional scan on the surface of the regional concrete is set.This detection device uses three -dimensional laser scanning to digitize the roughness of the concrete, and then obtains the three -dimensional point cloud data on the concrete surface, and then calculates the roughness of the concrete surface to achieve the purpose of accurately measure the roughness of the concrete surface.

Description

technical field [0001] The invention relates to the field of concrete surface quality detection devices, in particular to a handheld concrete roughness three-dimensional detection device and method. Background technique [0002] The existing concrete surface roughness detection mainly adopts the sand filling method or the sand topping method. The highest point of the unit area area is filled with fine sand or the entire measurement area is paved, and finally the roughness is calculated according to the sand volume. [0003] The above-mentioned measurement method has a relatively complicated operation process, and the measurement accuracy cannot be well guaranteed. SUMMARY OF THE INVENTION [0004] In order to overcome the deficiencies of the prior art, the present invention provides a handheld concrete roughness three-dimensional detection device and method. The detection device uses three-dimensional laser scanning to digitize the concrete roughness, and then obtains thre...
