Fig. 1 is a block diagram showing a structure of a vehicle-mounted lightweight road surface performance detection device according to the present invention.
Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in FIG. 1, the vehicle-mounted lightweight road surface performance detection device comprises a light source, a first camera, a GPS and a processor, wherein the light source is arranged at the front end of a detection vehicle, the first camera, the GPS and the processor are arranged on the detection vehicle, and the processor is respectively connected with the camera and the GPS.
The road surface detection process realized by the vehicle-mounted lightweight road surface performance detection device comprises the following steps:
and S1, detecting and recording the position of the vehicle on the standard road surface through GPS positioning on the standard road surface (or a newly built road surface, which is exemplified by the standard road surface below).
And S2, turning on a light source for detecting the front end of the vehicle, and shooting and storing a standard picture of the detected vehicle in the driving process through the first camera.
S3, when the road needs to be detected, the detected vehicle runs on the standard road surface through the GPS, the light source at the front end of the detected vehicle is turned on, the detected picture of the detected vehicle in the running process is shot through the first camera and transmitted to the processor, the processor compares the detected picture with the standard picture, if the detected picture has the abnormal picture information, the road surface is considered to be damaged, and therefore the position of the damaged road surface is determined through the position of the abnormal picture information. Specifically, the pictures can be gridded, that is, the pictures are gridded through a plurality of transverse lines and longitudinal lines, the number of the transverse lines and the longitudinal lines can be selected according to the precision requirement, the larger the number is, the smaller the grids into which the pictures are divided are, so that the judgment accuracy is higher, then the brightness and the intensity of the corresponding grid small blocks of the detected pictures and the standard pictures are compared, if the difference value of the brightness and the intensity of the two is beyond a set threshold value, the road surface is considered to be damaged, and the performance state of the road surface is judged.
In view of the above operation, the detection process is preferably performed in a night environment to avoid the influence of sunlight in the daytime and the occurrence of misjudgment.
As another preferred embodiment of the present invention, the detection vehicle is further provided with a light supplement device, and before the detection vehicle performs the road surface detection, the illumination brightness and intensity of the light source are detected at the starting point, and if the illumination brightness and intensity are lower than those of the standard image, the illumination brightness and intensity at the starting point can be made to be consistent with the detection state of the standard road surface by turning on the light supplement device, so as to ensure the accuracy of the detection.
As another preferred embodiment of the present invention, the inspection vehicle is further provided with a 360-degree electric adjustment base, and the first camera is arranged on the 360-degree electric adjustment base, and since it is difficult for the first camera to ensure the position of the image taken on the inspection vehicle to be consistent with the position of the image taken on the standard road surface, the image taken by the first camera is consistent with the image taken on the standard road surface by adjusting the 360-degree electric adjustment base.
In another preferred embodiment of the present invention, the inspection vehicle is further provided with a second camera, and the second camera is also connected with the processor. Due to the influence of GPS precision, when a detection vehicle detects a road surface, the absolute consistency of the position of the detection vehicle and the position of the detection vehicle on a standard road surface is difficult to ensure, therefore, a picture of a ground traffic signal line is further shot by a second camera, the picture is transmitted to a processor, the processor detects the position of the vehicle away from the ground traffic signal line according to the picture, whether the position of the detection vehicle away from the ground traffic signal line is the same as the position of the detection vehicle away from the ground traffic signal line on the standard road surface during detection is further judged, if the positions are different, an alarm signal is sent, the position of the detection vehicle away from the ground traffic signal line is adjusted to detect the consistency of the position of the vehicle and the position of the detection vehicle on the standard road surface, and the consistency of the shot.
