Lidar system for detecting obstructions through a protective window
The granted patent US12019186B2 describes a LIDAR system designed to enhance the detection and management of obstructions on a protective window associated with the system. The core functionality involves a processor that controls a LIDAR light source to emit light pulses and receives reflection signals from sensors. These signals are analyzed over a time period longer than the emitted pulse duration, allowing the system to differentiate between light reflected from the protective window and light from objects in the field of view. By comparing the temporal amplitude profile of the received signals with a known internal reflection signal, the system can identify the presence and type of obstructions, such as dirt or debris, on the protective window.
Further, the system incorporates advanced pattern recognition algorithms to detect specific obstruction patterns and compare them with stored reference patterns for various substances like mud, snow, or pollen. This capability enables the system to output detailed information about the obstruction, including a cleaning request tailored to the type of obstruction detected. Additionally, the processor can adjust the light source's parameters, such as intensity and sensitivity, to optimize performance based on the identified obstruction. Overall, the patent outlines a comprehensive approach to maintaining LIDAR functionality by effectively managing obstructions on the protective window.
