“… Limited coverage: although GPS measurement can provide wide-area data, it cannot be detected in signal-blind areas such as mountain roads and tunnels [ 19 ], and the resolution is not enough to obtain detailed Pavement-Section information [ 20 ]. Time and labor costs: the level tape measure method and theodolite sight distance method require manual measurement of road closures during measurement, and the time and labor costs are relatively high [ 21 ]. Devices such as laser cross-sections based on laser displacement sensors can only detect the cross-section of the pavement and have large data errors due to the lack of data fusion from sensors such as accelerometers and odometers.…”

The section detection of the pavement is the data basis for measuring the road smoothness, rutting, lateral slope, and structural depth. The detection of the Pavement-Section includes longitudinal-section inspection and cross-section inspection. In this paper, based on multiple laser displacement sensors, fused accelerometers and attitude sensors, and using vehicle-mounted high-speed detection, we design a sensor-fused pavement section data acquisition method, establish the relevant mathematical model, and realize the automatic acquisition of pavement longitudinal and transverse sections. The acceleration sensor is filtered to improve the accuracy of data acquisition, and the error of the detection system is calculated and analyzed. Through the actual measurement, the vehicle-mounted high-speed pavement profile detection method adopted in this paper can not only accurately detect the profile of the pavement profile, but also improve the detection efficiency, providing a cost-effective detection mode for road surface detection.

“…It is clear that the error of the rotation angle γ affect on the error of the landmark azimuth determination. The error of the rotation angle γ includes the error of the angle sensor [7]. The most precise angle sensors are optical encoders LIR-4200 (SKBIS, JSC, Russia) and RON-905 (Heidenhain, Germany) with limits of errors ±0,4 arcsec [8].…”
