Multiple laser stripe measurement is a vital technique in optical 3D measurement. In this study, we propose an adaptive step size gradient centerline extraction method based on a 2D linear filter to accurately extract laser stripe centerlines in complex measurement scenarios. Comprehensive comparative experiments demonstrate that our method enables more precise centerline extraction, exhibits enhanced stability, and yields lower measurement errors.
Multiple laser stripe measurement (MLSM) is a vital technique in optical three-dimensional (3D) measurement. The accurate extraction of the laser stripe centerlines plays a decisive role in achieving high measurement accuracy. However, complex 3D measurement scenarios pose challenges due to various interferences, such as optical interference caused by dense stripes and no-ideal distribution caused by non-uniform reflectivity. To address these challenges, we propose an adaptive step size gradient centerline extraction method based on an 2D linear filter. This method incorporates local adaptive variable parameters for fine-tuning while utilizing global parameters. We validate its performance by conducting comprehensive comparative experiments with two commonly used methods. The results demonstrate that our proposed method enables more precise centerline extraction, exhibits enhanced stability, and yields lower measurement errors in complex 3D measurement conditions and highlight the effectiveness and superior performance of our method.
