Abstract: To generate an image that captures a 360-degree horizontal view around a vehicle in a lidar system, four or more lidar sensors may be placed at the four corners of the vehicle. Each lidar sensor is phased 90 degrees apart and synchronously scans a respective 90-degree field of regard. The 90 degree fields of regard from each of the four or more lidar sensors may combine to scan a complete 360-degree field of regard around the vehicle.

Abstract: To solve depth of field issues when scanning, transmitting, and receiving light pulses in a lidar system, a receiver in the lidar system may include a lens having a lens plane in front of one or several photodetectors arranged on a detector plane. The lens plane and the detector plane may be nonparallel with respect to each other creating a wedge shaped depth of field. In this manner, return light pulses from far away and nearby targets may stay in focus.

Abstract: To identify the most important areas in front of a vehicle for avoiding collisions, a lidar system obtains a foveated imaging model. The foveated imaging model is generated by detecting the direction at which drivers' are facing at various points in time for several scenarios based on road conditions or upcoming maneuvers. The lidar system identifies an upcoming maneuver for the vehicle or a road condition and applies the identified maneuver or road condition to the foveated imaging model to identify a region of a field of regard at which to increase the resolution. The lidar system then increases the resolution at the identified region by increasing the pulse rate for transmitting light pulses within the identified region, filtering pixels outside of the identified region, or in any other suitable manner.
