[0040] The device or equipment models involved in this article are as follows:
[0041] The model of the laser radar 260 is: SCOPE-MINI;
[0042] The model of the data logger 270 is: VRTU4204-8AI.
[0043] Working principle: When in use, first install the sliding frame 330 to the rear of the vehicle body 190, and then use the sliding frame 330 to cooperate with the sliding block 320 and the sliding groove 370 to adjust the connecting rod 310, the connecting plate 120 and the bottom plate 110 up and down, adjust the distance between the bottom plate 110 and the scanning component 2 above the bottom plate 110 and the ground to a suitable position, and then use the fixing bolt 250 to cooperate with the locking nut 340 and the positioning support hole 380 to fix the sliding block 320, and then the vehicle body 190 is driven along the road marking, and the laser radar 260 cooperates with the first detection port 290 and the laser radar 260 in the detection fixing groove 180 through the first detection port 290. The glass beads in the marking are respectively tested for embedding through the first detection port 290 and the camera 261 through the second detection port 291, and the data is stored in the data collector 270.

The specific detection process is as follows: the laser radar 260 sends a laser signal to the road surface, performs a laser scan on the glass beads of the road marking, obtains the first contour data of the glass beads in the marking, and calculates the first average value of the exposed part of the glass beads according to the first contour data. The second contour data of the part of the glass beads exposed on the road surface is collected by the camera 261, and the second average size parameters of the part of the glass beads exposed on the road surface are calculated by the second contour data to determine and analyze the degree of glass beads embedded in the marking line. The height and angle of the bottom plate 110 are adjusted to repeat the detection and obtain the contour data again. The settlement degree is calculated according to the first average size parameter and the second average size parameter. The first average size parameter and the second average size parameter are fused and compared with the original glass bead size. The detected average size parameter and the original glass bead size parameter are compared to obtain the detection and recognition result, thereby obtaining the final degree of embedding of the road marking glass beads into the marking line (the size of the embedded marking line), realizing full coverage detection of various complex scenes of road marking glass beads construction, and improving the detection efficiency. Due to various changes such as elevation difference in the road area, the laser radar and high-definition camera detection and scanning will also be affected by changes in different environmental conditions. Therefore, the present invention detects the adhesion of road marking glass beads by fusing the two, which can effectively make up for the problems encountered in the existing scanning and detection using laser radar or high-definition camera alone, and can accurately detect and identify the adhesion of road marking glass beads, further improving the detection accuracy.
