Abstract: A method for processing point data obtained from a light detection and ranging (LiDAR) device is proposed. The method may include obtaining point cloud data including a plurality of point data for a plurality of detection points. The method may also include generating an image of the plurality of detection points based on the point cloud data. Each of the plurality of point data may include location information about a detection point and a geometrically enhanced intensity of the detection point. The geometrically enhanced intensity may be generated based on a combination of a reflection parameter related to the amount of light scattered at the detection point and a geometric parameter based on geometrical characteristic of the detection point.

Abstract: Disclosed are a method for sensing an emergency in response to a physical shock and a mental shock and an apparatus using the method. According to the method, whether a person is in an emergency state is determined by analyzing the physical shock and mental shock applied to the person and the emergency is automatically sensed without any effort on the part of the victim, whereby the rate at which an emergency is sensed in real time may be increased and the incidence of false determination on the emergencies may be reduced.
