“…In order to ensure the accuracy of the global calibration, a high-precision measuring device can be adopted [7][8][9][10][11]13,108,109]. The most common large-range measuring devices are theodolites, laser trackers, and laser range finder.…”

“…The most common large-range measuring devices are theodolites, laser trackers, and laser range finder. Lu and Li [8] develop a high precision global calibration method for large-scale visual measurement system using two theodolites. This method places a calibration target into the field of view of a camera, uses a theodolite coordinate measurement system (TCMS) to measure the 3D coordinates of the markers on the calibration target, and then calculates the positional relationship between the calibration target and the camera, and resolves the transformation matrix between the camera and TCMS.…”

“…The results are very consistent with each other and standard deviations of all the parameters are very small, which indicate that the proposed method is stable. In order to evaluate the calibration accuracy, the vision system is also calibrated by a double theodolites based method 9 which utilizes two Leica T1800 theodolites (angle measurement accuracy ≤0.5 in.). Both results are listed in Table 2.…”

Abstract. In some computer vision applications, it is necessary to calibrate the geometry relationships of nonoverlapping cameras. However, due to lacking a common field of view, the calibration of this camera topology is quite difficult. A calibration method for nonoverlapping cameras is proposed and investigated. The proposed method utilizes several light planes, which can be generated by a line laser projector or a rotary laser level, as the calibration objects. The fact that local light planes available in different cameras are identical in global coordinates is used to recover the geometries. Results on both synthetic and real data show the validity and performance of the proposed method. The given method is simple and flexible, which can be used to calibrate geometry relationships of cameras located in large-scale space without expensive equipment such as theodolites and laser trackers. © The Authors.

“…But most solutions require additional apparatus to assist the calibration, such as the theodolite pairs, CMMs or the laser trackers [3][4][5]. These machines usually have a higher accuracy than that of the visual measurement system to be calibrated (e.g.…”
