The present invention relates to a multi-channel lidar sensor module capable of measuring at least two target objects using one image sensor. The multi-channel lidar sensor module according to an embodiment of the present invention includes at least one pair of light emitting units configured to emit laser beams and a light receiving unit formed between the at least one pair of emitting units and configured to receive at least one pair of reflected laser beams which are emitted from the at least one pair of light emitting units and reflected by target objects.

Multi-channel LiDAR sensor module

A LiDAR device including a emitting unit configured to emit a laser, a detecting unit configured to detect the laser, and a controller configured to control the emitting unit and the detecting unit, wherein the controller is configured to operate the LiDAR device at in at least a first operation mode or a second operation mode in which power consumption per unit time is lower than that of the first operation mode, and wherein the controller is configured to switch an operation mode of the LiDAR device from the first operation mode to the second operation mode when the controller receives a first trigger signal from a first device, and switch the operation mode of the LiDAR device from the second operation mode to the first operation mode when the controller receives a second trigger signal from the first device.

LiDAR device having a smart power management system and an operating method of the lidar device implementing the smart power management system

A light detection and ranging (lidar) device includes: a lower base; an upper base; a laser emitting unit for emitting a laser in a form of a point light source; a nodding mirror for transforming the laser in the form of the point light source to a line beam pattern which is perpendicular to the lower base, wherein the nodding mirror reflects the laser emitted from the laser emitting unit; a polygonal mirror for transforming the line beam pattern to a plane beam pattern and receiving a laser reflected from an object; and a sensor unit for receiving the laser reflected from the object via the polygonal mirror.

LiDAR device

The present invention relates to a light detecting and ranging (LiDAR) device for obtaining information on a distance from an object using laser light. A light detection and ranging (LiDAR) device according to the present invention may include: a laser emitting unit configured to emit a laser, a first scanner configured to obtain the laser emitted by the laser emitting unit and continuously change a travel path of the laser so as to extend a irradiation area to a line shape, a second scanner configured to obtain and continuously changes the travel path of the laser projected from the first scanner which has a line-shaped irradiation area, so as to extend the irradiation area to a plane shape, and a sensor configured to detect a laser reflected from an object located in a scanning area by the laser projected from the second scanner, wherein the first scanner comprises nodding mirror which extend the irradiation area to a line shape by changing a travel path of the laser while nodding within a preset angle range, and wherein the second scanner comprises a rotating polygon mirror which changes the travel path of the laser which has the line-shaped irradiation area by rotating on one axis so as to extend the irradiation area to a plane shape.

Multi-channel lidar sensor module

Provided are an apparatus and a method for detecting an obstacle. The apparatus includes a light-emitting unit configured to emit a plane beam by converting a laser beam into the plane beam having a rectangular shape; a light reception unit configured to receive the laser beam which is emitted from the light-emitting unit and reflected from the obstacle; and a control unit configured to measure a distance to the obstacle by using the laser beam received in the light reception unit. Thus, an obstacle is detected by using the plane beam having a rectangular shape, so that the measurement range may be enlarged upwardly and downwardly.
