  • Publication number: 20230410712
    Abstract: In an automatic gamma adjustment system with environmental adaptability, the system is installed in a display device and an image signal source is selected, such that an image signal is received and converted into first YUV signals, while detecting the surrounding situation to obtain at least one environmental data, and obtaining a gamma control parameter of a display screen of the display device according to the environmental data. When the environmental data is calculated to obtain a maximum brightness current value, the gamma control parameter is used to calculate the first YUV signals as second YUV signals, and the maximum brightness current value and the second YUV signals are sent to the display device for displaying the image. Therefore the grayscale layering effect of an image presented to people can be adjusted by automatically correcting the gamma value according to the surrounding situation at any time.

  • Publication number: 20230351689
    Abstract: The present disclosure provides systems and methods that combine physics-based systems with machine learning to generate synthetic LiDAR data that accurately mimics a real-world LiDAR sensor system. In particular, aspects of the present disclosure combine physics-based rendering with machine-learned models such as deep neural networks to simulate both the geometry and intensity of the LiDAR sensor. As one example, a physics-based ray casting approach can be used on a three-dimensional map of an environment to generate an initial three-dimensional point cloud that mimics LiDAR data. According to an aspect of the present disclosure, a machine-learned geometry model can predict one or more adjusted depths for one or more of the points in the initial three-dimensional point cloud, thereby generating an adjusted three-dimensional point cloud which more realistically simulates real-world LiDAR data.
