LED Car lidar system interlocking LED head lamp

摘要

An LED that extends the measurement distance by using a light source of a car LED headlamp capable of emitting high-intensity light as an illumination light source for Lidar, and compensates for the degradation of resolution using a separate distance calculation algorithm. It relates to a headlamp-linked automotive lidar system, which controls the brightness of the headlight according to the headlight brightness control signal of the vehicle, but transmits a high-frequency light source synchronized with the operating frequency and phase of the lidar. A synchronization signal synchronized with the operating frequency and phase is transmitted, the phase detected from the light received from the subject is compared with the phase provided to the lighting device to measure the phase delay, and the distance to the subject generated by the measured phase delay Implement an LED headlamp-linked car lidar system, including a 3D imaging device that outputs a measurement signal as a 3D image signal, and a distance calculator that performs long distance and precise distance calculation by combining 3D image signals output through the 3D imaging device. do.
