“…Mishra, Pandey, and Saripalli (2020) presented a method, which uses the data collected by flat plates placed in different postures in the common field of view of LiDAR and camera, then a function model is established according to geometric constraints, and the LiDAR-Camera system is calibrated using non-linear least squares. Chen et al (2019) used a method based on the laser tracer multistation measurement system to calibrate the angular positioning deviation of a high-precision rotary table; according to their experimental results, the angular positioning deviation of the high-precision rotary table was as low as ±0.9", and the error of the calibration method was ±0.4".…”

The measurement accuracy of the Mobile Mapping System (MMS) is the main problem, which restricts its development and application, so how to calibrate the MMS to improve its measurement accuracy has always been a research hotspot in the industry. This paper proposes a position and attitude calibration method with error correction based on the combination of the feature point and feature surface. First, the initial value of the spatial position relationship between each sensor of MMS is obtained by close-range photogrammetry. Second, the optimal solution for error correction is calculated by feature points in global coordinates jointly measured with International GNSS Service (IGS) stations. Then, the final transformation parameters are solved by combining the initial values obtained originally, thereby realizing the rapid calibration of the MMS. Finally, it analyzed the RMSE of MMS point cloud after calibration, and the results demonstrate the feasibility of the calibration approach proposed by this method. Under the condition of a single measurement sensor accuracy is low, the plane and elevation absolute accuracy of the point cloud after calibration can reach 0.043 m and 0.072 m, respectively, and the relative accuracy is smaller than 0.02 m. It meets the precision requirements of data acquisition for MMS. It is of great significance for promoting the development of MMS technology and the application of some novel techniques in the future, such as autonomous driving, digital twin city, urban brain et al.

Recently, a four-axis coordinate measuring machine, which consists of three linear axes and a single rotary axis, has been more widely used than a traditional three-axis coordinate measuring machine. The volumetric error influences the accuracy of the four-axis coordinate measuring machine. 27 parametric errors contribute to the volumetric error. This study proposes a new methodology to analyze the parametric and volumetric error of the four-axis coordinate measuring machine using a hole plate. First, the hole plate setup sequentially in three different planes. We measured the hole plate by using five different styluses. Second, 27 parametric errors were analyzed using the coordinate deviations. The volumetric error was constructed using the homogeneous transform matrixes. The volumetric error ranges were from 0.35 µm to 1.55 µm and from 0.35 µm to 2.83 µm without and with the single rotary axis. Third, three commercial instruments, namely a laser interferometer, an autocollimator, and a polygon-autocollimator, were used to validate the proposed methodology to verify the measured parametric errors. The absolute maximum differences, compared with the laser interferometer for three parametric positioning errors and the autocollimator for six parametric rotational errors for the three linear axes, were 0.56 µm and 0.54", respectively. Moreover, the absolute maximum difference of one parametric positioning error for the single rotary axis, comparing with the polygon-autocollimator, was 0.75". The En-values were 0.27, 0.54, and 0.27, respectively. The results demonstrate the proposed methodology's effectiveness and reliability to the industry's four-axis coordinate measuring machines.

“…Influences under this point will affect the result in reality. In 2019, H. Chen [18] introduced a multi-station measurement system using a laser tracer applied on large high-precision rotary tables; however, the system faces concentricity problems between the laser tracer and the rotary table. In 2021, D. Ma [19] executed a new measurement method as an independent system for all motion errors of a rotary axis based on a polyhedral prism.…”

The angular positioning error of the rotary stage causes low quality in milling various angles of a workpiece. This study proposes a solution that could improve these issues by using our Laser R-test for angular positioning calibration and compensation of the five-axis machine tools in compliance with the simultaneous measurement path of ISO regulations: ISO 10791-6 and ISO 230-2. System uncertainty analysis and calibration were implemented for system prediction. The measurement method proposed in this paper could solve concentricity problems between measurement devices and the rotary table by applying the Cosine theorem with a Cartesian coordinate system. Further, we used the commercial instrument XR20-W (Renishaw, UK) rotary axis calibrator to verify and compare the measured results on a CNC machine tool. The applied system achieves an angular error of 0.0121 degrees for actual workpieces and is smaller than the referring commercial system, which achieves an error of about 0.0022 degrees. The system in this research is useful for five-axis machine tool full calibrations.
