摘要： This application discloses a point cloud densification method and apparatus, a storage medium, and a LiDAR device. The method is applied to a LiDAR device, the LiDAR device includes an emitter group and a scanning apparatus, and the method includes: obtaining a point cloud densification multiple of a detection field of view at each level; obtaining an interval between scanning lines corresponding to two adjacent emissions based on the point cloud densification multiple of the detection field of view at each level; and performing scan based on the interval between the scanning lines corresponding to the two adjacent emissions. In this application, ROI can be densified by controlling an interval between scanning lines corresponding to two adjacent emissions and detection efficiency of the LiDAR device is improved while safety of human eyes is ensured.

摘要： A localization method for an automated or autonomous aircraft (100) comprises the following steps: acquiring images of an observation area (110) in front of and or below the aircraft (100) while the aircraft (100) is approaching a given destination (150) resulting in a time series of images, wherein a plurality of beacons (120) are arranged in the observation area (110) in a predetermined known spatial relationship to each other and to the destination (150), each beacon (120) intermittently emitting light in a predetermined known blinking pattern (160); recognizing and tracking light source objects throughout the time series; determining beacon objects from among the recognized and tracked light source objects based on the known blinking patterns of the beacons (120); and determining a state of the aircraft (100) with respect to the destination (150) based on the beacon objects thus determined.

摘要： The invention relates to. a system for providing 3D surveying of an environment by an unmanned ground vehicle (1), UGV, and an unmanned aerial vehicle (2), UAV. The system comprises two lidar devices (3, 4), one specifically foreseen to be mounted on the AGV (1), AGV lidar device (3), and another one specifically foreseen to be mounted on the UAV (2), UAV lidar device (4). The system further includes a reference unit (15) comprising a first and a second marker (16A, 16B, 17, 30), wherein the first and the second marker (16A, 16B, 17, 30) are in a spatially fixed arrangement with respect to each other. An automatic detection of the first marker (16A, 16B, 17, 30) is carried out, upon which a coordinative measurement of the first marker (16A, 16B, 17, 30) by the first lidar device (3, 4) is carried out to determine relative position data providing relative position information of the first marker (16A, 16B, 17, 30) with respect to the first lidar device (3, 4). The relative position data and a spatial 3D information on the spatially fixed arrangement of the first and the second marker (16A, 16B, 17, 30) with respect to each other are then taken into account to carry out an automatic detection of the second marker (16A, 16B, 17, 30) and to carry out a coordinative measurement of the second marker (16A, 16B, 17, 30) by the second lidar device (3, 4). The coordinative measurement of the first marker (16A, 16B, 17, 30) and the coordinative measurement of the second marker (16A, 16B, 17, 30) are then taken into account for a referencing of lidar data of the UGV lidar device (3) and lidar data of the UAV lidar device (4) with respect to a common coordinate system.

摘要： Aspects and implementations of the present disclosure address challenges of the existing technology by enabling lidar-assisted identification and characterization of visibility-reducing media (VRM) such as fog, rain, snow, dust in autonomous vehicle applications, using lidar sensing. VRM can be identified and characterized using a variety of techniques, including analyzing a spatial distribution of low-intensity lidar returns, detecting pulse elongation of VRM-returns associated with reflection from VRM, determining intensity of VRM-returns, determining reduction of intensity of returns from various reference objects, and other techniques.

摘要： Thermal imaging and navigation systems and related techniques are provided to improve the operation of manned or unmanned mobile platforms, including passenger vehicles. A thermal imaging navigation system includes a thermal imaging system and a logic device configured to communicate with the thermal imaging system. The thermal imaging system includes a thermal imaging module configured to provide thermal image data corresponding to a projected course for a mobile platform. The logic device is configured to receive the thermal image data, receive orientation and/or position data corresponding to the thermal image data, and generate maneuvering obstacle information corresponding to the projected course based, at least in part, on the orientation and/or position data and/or the thermal image data.
