Posture planning method for complex feature measurement using a single-line laser scanner.

ABSTRACT

A single-line laser scanner is commonly utilized for measuring complex surfaces and contours. However, achieving automatic implementation of this scanner poses challenges in terms of designing a measurement posture that considers measurement accuracy, path planning, and the positioning of auxiliary equipment. This ensures non-interference during the measurement process. In this study, we focus on the application of T-SCAN. First, we construct a measurement posture parameter model for T-SCAN and analyze the viewpoint position's coverage of the measurement area. Second, we propose a measurement path planning method based on scanning posture to minimize overlapping areas. Lastly, we present a measurement station planning method based on scanning postures and analyze the transfer error of the measurement targets to establish a unified measurement field. Experimental results demonstrate that, after the posture adjustment process, the average distance deviation between the measurement data and the theoretical model is significantly reduced.
