Embodiment Construction

[0035] In order to clearly illustrate the solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings.

[0036] The calibration process in the embodiment of the present invention includes:

[0037] S11: Among the m lasers on the rut beam, determine the installation angle α of each laser i and the transverse coordinate a i ; Wherein, the horizontal coordinate a i is the lateral coordinate value of the i-th laser relative to the reference laser, the reference laser is a laser located in the middle of the rut beam, and i=1~m;

[0038] For details, see Figure 4 , there is a rut detection device with m=13 lasers, and the design installation parameters of each laser on the rut beam (α i ,ai,BAi);

[0039] where α i is the laser installation angle numbered i, clockwise is a positive value, and counterclockwise is a negative value; ai is the horizontal coordinate value of the i-th la...

Abstract

The invention discloses a calibration method of a multi-point co-beam rut detection device and a cross-section determination method. The calibration method comprises that the installation angle ai and horizontal coordinate ai of each laser among m lasers on a rut beam are determined, wherein the horizontal coordinate ai is a horizontal coordinate value, relative to a reference laser, of the ith laser, the reference laser is the laser located at the middle position of the rut beam, the i=1-m; the reading Hi irradiating on a calibration scale or a road of the laser light of each laser is collected; among the m lasers, the n lasers installed vertically are chosen, and the horizontal dip angle beta0 is determined by the reading Hi and the horizontal coordinate ai of the n lasers; the vertical position parameter Bi of the laser i is calibrated by using the horizontal dip angle beta0, i=1-m. The method provided by the invention has the advantage that the measurement accuracy of the cross-section can be effectively improved.

Description

technical field [0001] The invention relates to the field of road surface measurement, in particular to a calibration method and a cross-section determination method of a multi-point common beam rutting detection device. Background technique [0002] Rutting is one of the main damage forms of high-grade highways with large traffic volume. The formation of ruts on the road surface will not only affect the comfort of driving on the road surface, but also cause water accumulation in the rut area in rainy days, causing safety hazards. Rutting exceeding a certain depth is also an important sign of structural damage to the pavement. Therefore, rutting detection is one of the important contents of road condition detection. my country's road technical condition assessment standards require that all secondary and above roads should be inspected and inspected every year. evaluate. [0003] The multi-point co-beam rut detection device has always been the mainstream detection method for...
