Sistem penglihatan cahaya berstruktur adalah berdasarkan fakta bahawa lokasi piksel cahaya dalam imej mempunyai perkaitan unik dengan kedalaman objek. Walau bagaimanapun, aplikasinya adalah terhad kepada sifat permukaan objek dan keadaan pencahayaan. Kertas kerja ini membentangkan sistem penglihatan yang teguh untuk pemerolehan data permukaan 3-D yang tepat berdasarkan cahaya berstruktur optimum. Untuk mencapai pengukuran kedalaman bagi pemandangan dinamik, pemerolehan data mesti dilakukan dengan hanya satu imej. Susunan khas kami menjadikan imej jalur cahaya kekal tajam manakala latar belakang menjadi kabur. Selain itu, pendekatan pengaturcaraan dinamik dicadangkan untuk menjejaki laluan optimum manakala pancaran laser tidak dapat dilihat atau mencapah di bawah keadaan yang melampau. Prinsip dan matematik yang diperlukan untuk melaksanakan algoritma dibentangkan. Kekukuhan sistem terhadap ralat yang tidak ditentukur ditunjukkan.

Abstract: Structured light vision systems are based on the fact that the pixel location of light in an image has a unique association with the object depth. However, their applications are mainly limited to the properties of the object surface and the lighting conditions. This paper presents a robust vision system for accurate acquisition of 3-D surface data based on optimal structured light. To achieve depth measurement for a dynamic scene, the data acquisition must be performed with only a single image. Our special arrangement makes the image of the light stripe remaining sharp while the background becomes blurred. Moreover, a dynamic programming approach is proposed to track the optimal path while the laser beam is invisible or divergent under extreme condition. The principle and necessary mathematics for implementing the algorithm are presented. The robustness of the system against uncalibrated errors is demonstrated.

AB - Structured light vision systems are based on the fact that the pixel location of light in an image has a unique association with the object depth. However, their applications are mainly limited to the properties of the object surface and the lighting conditions. This paper presents a robust vision system for accurate acquisition of 3-D surface data based on optimal structured light. To achieve depth measurement for a dynamic scene, the data acquisition must be performed with only a single image. Our special arrangement makes the image of the light stripe remaining sharp while the background becomes blurred. Moreover, a dynamic programming approach is proposed to track the optimal path while the laser beam is invisible or divergent under extreme condition. The principle and necessary mathematics for implementing the algorithm are presented. The robustness of the system against uncalibrated errors is demonstrated.
