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 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

Sharing sensor data between a first device and a second device comprising obtaining a set of point data from at least one of sensors located in the first device, determining a property data of the subset of point data based on the subset of point data, generating a first sharing data for sharing with the second device based on the property data, transmitting the sharing data to the second device, identifying an occurrence of an event at a first time point, and generating a second sharing data different from the first sharing data. A content of the second sharing data includes at least a portion of the set of point data obtained within a first time period including the first time point.

Method of sharing and using sensor data

Sharing sensor data of a first device with a second device includes obtaining a set of point data from at least one of a sensors located in the first device, generating a first property data of the first subset of point data based on the first subset of point data, generating a sharing data including at least a portion of the first subset of point data and the first property data, and transmitting the sharing data to the second device. If a class of a first object included in the class information a class in which personal information must be protected, a content of the sharing data includes a privacy protection data in which the first subset of point data is processed such that personal information of the first object does not identified by the second device.

Multi-channel lidar sensor module

A laser beam apparatus that is used for detecting vehicles in an intelligent traffic system according to an embodiment includes: a light source generating a laser beam of a short pulse; an optical transmission system converting the laser beam into a line beam; and an optical reception system receiving a beam dispersed rearward and reflected and returned when the line beam is radiated to a vehicle, and calculating a distance value from a reception time difference between the laser beam and the reflected beam, in which a first lens and a second lens that receive a laser from the light source are sequentially arranged in the optical transmission system, and the length of a horizontal axis of the line beam is increased or decreased to fit to the width of a road to be measured, by adjusting the distance between the light source and the first lens. Accordingly, it is possible to find out the current traffic situation in real time by accurately finding out whether there are vehicles passing through a predetermined area, using the lasers that are radiated from the laser detection apparatus regardless of the sizes of roads.
