Enhanced lidar data generation using image comparison
The patent US12072420B2 outlines a method and system for generating enhanced lidar data of a scene by integrating lidar and image data. The process begins with the acquisition of lidar data, which consists of multiple lidar points, and a series of images captured by an image sensor. For each lidar point, the method determines the position of the lidar sensor at the time of data collection and compares it to the position of the image sensor for each image. This comparison allows the identification of the "best" image for each lidar point, based on factors such as look angle, position, or vector similarity. The corresponding pixel from the selected image is then used to assign color to each lidar point, resulting in enhanced lidar data that incorporates spectral information from the images.
Additionally, the patent describes the inclusion of trajectory and orientation data to further refine the sensor positioning during data collection. The system is designed to be mounted on a vehicle, facilitating real-time data acquisition and processing. The enhanced lidar data can be displayed as a mapping, providing a comprehensive visual representation of the scene. This innovative approach aims to improve the quality and usability of lidar data by leveraging complementary image data, thereby enhancing applications in fields such as autonomous navigation, environmental monitoring, and urban planning.
