Signal processing device, signal processing method, and program
The present disclosure relates to a signal processing device that enables detection of the distance between an imaging device and a subject using an imaging device with high versatility, a signal processing method, and a program. A determination part classifies pixels to a plurality of pixel groups, and determines a pair of a first pixel group and a second pixel group using for detection of distance between the imaging device and the subject from a plurality of pixel groups on the basis of a charge accumulation period for each pixel group of the imaging device in which charge accumulation period is controlled, and a light projection period of pulse light projected toward the subject of the imaging device, for each pixel group. The present disclosure can be applied to, for example, a distance detection device or the like.

A method for recognizing a contamination of a beam path of a LIDAR system is described, including recognizing the contamination by the LIDAR system based on LIDAR measured data, which have been obtained during an optical scanning of surroundings of the LIDAR system.
Three-dimensional map generation system, three-dimensional map generation method, and computer readable medium
A three-dimensional map generation system generates three-dimensional map information using measured data acquired by a measuring vehicle which moves within a measurement area. A generation unit regards a data lacking area which is acquired from the measurement area based on first measured data transmitted from the measuring vehicle and which lacks measured data for generating a three-dimensional map, as a defective area, and generates interpolation data for interpolating three-dimensional map information of the defective area.
System and method for adaptive object-oriented sensor fusion for environmental mapping
The present disclosure relates to a mapping system adapted for detecting objects in an environmental scene, by scanning an environmental scene with propagating energy, and receiving reflected energy back from objects present in the environmental scene, in a prioritized manner, for later use. The system may comprise an imaging subsystem which includes a detection and ranging subsystem for initially identifying primitive objects in the environmental scene. The imaging subsystem may also include an identification and mapping subsystem for prioritizing the primitive objects for further scanning and analysis, to ultimately identify one or more of the primitive objects as one or more abstract objects. An environmental model, updated in real time, is used to maintain a map of the primitive objects and the known abstract objects within the environmental scene, as new primitive objects and new abstract objects are obtained with repeated scans of the environmental scene.
Lidar based detection of road surface features
An AV is described herein. The AV includes a lidar sensor system. The AV additionally includes a computing system that executes a road surface analysis component to determine, based upon lidar sensor data, whether a road surface feature is present on or in a roadway in a travel path of the AV. The AV can be configured to initiate a mitigation maneuver responsive to determining that the road surface feature is present. Performing the mitigation maneuver causes the AV to avoid the road surface feature or decelerate prior to reaching the road surface feature, thereby improving the apparent quality or comfort of the ride to a passenger of the AV.
Point cloud registration for LiDAR labeling
The subject disclosure relates to techniques for detecting an object. A process of the disclosed technology can include steps for receiving three-dimensional (3D) Light Detection and Ranging (LiDAR) data of the object at a first time, generating a first point cloud based on the 3D LiDAR data at the first time, receiving 3D LiDAR data of the object at a second time, generating a second point cloud based on the 3D LiDAR data at the second time, aggregating the first point cloud and the second point cloud to form an aggregated point cloud, and placing a bounding box around the aggregated point cloud. Systems and machine-readable media are also provided.
Fiber-bundled frequency-shifted transmitter for direct detection LIDAR
A method includes generating, using a transmitter, an optical signal for each fiber incoherently combined in a fiber bundle. The method also includes transmitting the optical signal from each fiber as pulses at a target. The method further includes receiving, using a receiver array, the pulses of the optical signals and identifying one or more parameters of the target based on the pulses of the optical signals.
