AbstractStructured light plays an important role in visual sensing system of various applications. At present, many types of structured light are available throughout the market. Among different types of structured light, cross-line structured light (CLSL) has been also employed in some visual sensing systems. However, it seems that the existing calibration methods are not practical and simple for users. In this paper, a calibration technique is proposed as an alternative for those who are seeking for a practical and simple calibration. A regular chessboard is modified in order to have intersections between light stripes and additional lines. Two views of the CLSL captured during camera calibration process give sufficient information for estimating the parameters of light planes. Simple image processing techniques are applied to the images yielding 3D coordinates of points on the light planes. Based on three non-collinear 3D points, the parameters of the light planes are computed. The experimental results prove that the accuracy of the calibration is acceptable and suitable for moderate precise measurement systems. (C) 2016 Elsevier GmbH. All rights reserved.
