Abstract
A LiDAR device with detector channel grouping is described in this disclosure. The LiDAR device can include a laser pulse scanner configured to scan laser pulses in a plurality of directions; a detector array that includes a plurality of adjacent detector channels; and a controlling unit configured to activate a group of adjacent detector channels of the plurality of adjacent detector channels corresponding to each of the plurality of directions based on one or more of an image width on the detector array corresponding to that direction after a laser pulse hits a target object, a measured ambient intensity from that direction, a reflectivity of the target object, or a distance of the target object.

A light detection and ranging (LiDAR) device, comprising:
- a laser pulse scanner configured to scan laser pulses in a plurality of directions;
- a detector array that includes a plurality of adjacent detector channels;
- and
- a controlling unit configured to activate a group of adjacent detector channels of the plurality of adjacent detector channels corresponding to each of the plurality of directions based on one or more of an image width on the detector array corresponding to that direction after a laser pulse hits a target object, a measured ambient intensity from that direction, a reflectivity of the target object, or a distance of the target object.
A method applied to a light detection and ranging (LiDAR) device, comprising:
- receiving reflected illumination from one of a plurality of directions, wherein the LiDAR device is configured to scan laser pulses in each of the plurality of directions;
- measuring an ambient intensity in the direction;
- and
- activating a group of adjacent detector channels of the plurality of adjacent detector channels corresponding to each of the plurality of directions based on one or more of an image width on the detector array corresponding to that direction after a laser pulse hits a target object, a measured ambient intensity from that direction, a reflectivity of the target object, or a distance of the target object.
A circuit embedded in a light detection and ranging (LiDAR) device, wherein the circuit is configured to cause the LiDAR device to perform operations comprising:
- receiving reflected illumination from one of a plurality of directions, wherein the LiDAR device is configured to scan laser pulses in each of the plurality of directions;
