The patent application (Publication Number: US20240037767A1) describes a 3D sensing system that includes a liquid crystal lens, a projector, an image sensor, and a circuit. The system is designed to generate structured light patterns, capture corresponding images, calculate depth information, and assess image quality. If the quality requirement is not met, the system adjusts the pattern and captures a new image to improve accuracy. The circuit can also analyze brightness levels, match sensing areas with dots, and calculate depth values to generate a depth map. Additionally, the system can store predetermined patterns, rotate or shift dots in the pattern, and adjust dot density to enhance decoding success.

Furthermore, the patent application outlines a 3D sensing method involving providing a light beam to a liquid crystal lens, capturing images, calculating depth information, and evaluating image quality. The method includes steps to assess brightness levels, match sensing areas with dots, calculate decoded rates, and adjust dot density for successful decoding. Additionally, the method involves storing predetermined patterns, rotating or shifting dots in the pattern, and combining depth information to generate a depth map. These innovative techniques aim to enhance the accuracy and efficiency of 3D sensing systems, offering potential advancements in various applications requiring precise depth mapping and image quality assessment.
