Abstract:Current domestic and international calibration specifications for structured light 3D measurement systems do not specify calibration methods for scenarios where the surfaces of measured objects are various non-diffuse reflective surfaces, and thus cannot fully meet the actual calibration needs. To address this issue, our research team analyzed the actual calibration scenarios of structured light 3D measurement systems, defined translucent surfaces, highly reflective surfaces and high dynamic range reflectivity surfaces from the perspective of optical properties, and designed standards applicable to different surfaces. In accordance with actual requirements, we formulated specific calibration methods, realizing the calibration of the capability of structured light 3D measurement systems to measure the geometric parameters of various non-diffuse reflective surfaces. The calibration method for structured light 3D measurement systems for various non-diffuse reflective surfaces proposed by our research team supplements and perfects the existing calibration methods for structured light 3D measurement systems, and plays an important role in promoting the development of structured light 3D measurement technology toward precision and standardization.
