Abstract
The present application provides a signal receiving apparatus, including: a photosensitive array; a data selection module, connected to the photosensitive array, configured to determine target pixels for outputting sampled data in each scan according to a current scanning mode of the radar system and to transmit the sampled data output by the target pixels to an operation processing module; and the operation processing module, connected to the data selection module, configured to process and compute the sampled data output by the target pixels to obtain pixel detection results corresponding to the target pixels.
Claims14
A signal receiving apparatus, comprising:
- a photosensitive array, wherein the photosensitive array comprises a plurality of photosensitive elements, groups of photosensitive elements in the photosensitive array form pixels, each pixel comprises one or more photosensitive elements, and the pixels receive echo light beams through internal photosensitive elements and output corresponding sampling data;
- a data selection module, connected to the photosensitive array, configured to determine target pixels for outputting sampling data in each scanning operation according to a current scanning mode of a radar system and to transmit the sampling data output by the target pixels to a computing and processing module, wherein the number of the target pixels is less than the number of pixels in the photosensitive array, and the number of the target pixels is determined according to the current scanning mode;
- and
- the computing and processing module, connected to the data selection module, configured to process and compute the sampling data output by the target pixels to obtain pixel detection results corresponding to the target pixels, wherein, in each scanning operation, the data selection module only selects sampling data output by a portion of the pixels in the photosensitive array to be transmitted to the computing and processing module.
A receiving chip for a LIDAR, comprising:
- a photosensitive array, wherein the photosensitive array comprises a plurality of photosensitive elements, groups of photosensitive elements in the photosensitive array form pixels, each pixel comprises one or more photosensitive elements;
- the pixels receive echo light beams through internal photosensitive elements and output corresponding sampling data;
- a system-on-chip, connected to the photosensitive array, configured to implement a signal processing method comprising:
- determining target pixels for a current scanning operation according to a current scanning mode;
- determining a pixel detection result for each of the target pixels according to sampling data of the target pixels;
- and
- acquiring point cloud data of a detection area according to the pixel detection results obtained from multiple scanning operations.
