“…Through the error analysis and calculation of the acceleration sensor, attitude sensor and integral algorithm, it can be seen that the maximum error caused by the acceleration integral algorithm itself is 0.32 mm, and the maximum measurement error caused by the vehicle attitude is 5.25 mm (measurement error caused by pitch angle is 0.0024 mm + measurement error caused by roll angle is 5.24 mm), and the system uses a laser displacement sensor to measure a maximum error of 0.50 mm [29] (provided by the device parameters). Therefore, the comprehensive error of the system is: δ s = δa + 5.25 + 0.5 + 0.32 = 0.0248 × 324λ 2 25v 2 + 6.07 mm (19) To have a more intuitive understanding of the error, formula (15) can be used to calculate the system measurement error under different vehicle speeds and different road surface waveforms, the error data is shown in Table 1.…”

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.

This paper deals with the concept of the automated calibration design for inspection systems using laser sensors. The conceptual solution is based on using a laser sensor and its ability to scan 3D surfaces of inspected objects in order to create a representative point cloud. Problems of scanning are briefly discussed. The automated calibration procedure for solving problems of errors due to non-precise adjustment of the mechanical arrangement, possible tolerances in assembly, and their following elimination is proposed. The main goal is to develop a system able to measure and quantify the quality of produced objects in the environment of Industry 4.0. Laboratory measurements on the experimental stand, including the principal software solution for automated calibration of laser sensors suitable for gear wheel inspection systems are presented. There is described design of compensation eccentricity by Fourier transform and sinusoidal fitting to identify and suppress the first harmonic component in the data with high precision measuring.

“…The laser displacement sensor based on the triangulation method has the advantages of large range, high precision, and strong anti-interference. It can be used in this situation as an economical measuring element 5 . Due to the limitation of the measurement principle, although the laser displacement sensor has high repeated measurement accuracy, it has serious high-order nonlinear system errors, so it is necessary to perform error compensation in engineering applications [6][7] .…”

The laser displacement sensor based on the triangulation method has the advantages of large range, high precision, and strong anti-interference. Due to the limitation of the measurement principle, although the laser displacement sensor has high repeated measurement accuracy, it has serious high-order nonlinear system errors. Considering that in some measurement occasions, only a few local measurement intervals within the range are used. In this paper, a local nonlinear error calibration algorithm based on C2 continuous interpolation was proposed. A nonlinear calibration model was established by intensive calibration data acquisition in the local interval of the measurement application. The model can be smoothly connected with the original linear calibration model. At the same time, the measurement accuracy of the local area is greatly improved without affecting the accuracy of other intervals.
