Application: System and method for reducing stray light interference in optical systems (Patent ID: US20240073545A1)
The patent by LG Display Co Ltd. discloses a method and system for reducing optical interference in an optical sensor by detecting signals with reflected and stray light components, estimating stray light intensity in each pixel sensor, adjusting noise probability and signal confidence score based on the estimated stray light intensity. The method further involves classifying points in a point cloud, adjusting the intensity of reflected light, and filtering points based on signal confidence score.
The system includes an optical sensor device with pixel sensors, a processor, and a computer-readable storage medium containing programming instructions for implementing the method. The system allows for estimating stray light intensity, adjusting noise probability, and signal confidence score, classifying points in a point cloud, adjusting reflected light intensity, and filtering points based on signal confidence score. The programming instructions also involve adjusting noise probability, signal confidence score, and filtering points based on the adjusted values, providing a comprehensive solution for reducing optical interference in optical sensors.
