摘要： A novel neural modeling framework Neural Transient Field (NeTF) is provided for non-line-of-sight (NLOS) imaging. NeTF recovers the 5D transient function in both spatial location and direction, and the training data input is parametrized on the spherical wave-fronts. A Markov chain Monte Carlo (MCMC) algorithm is used to account for sparse and unbalanced sampling in NeTF.

摘要： An autonomous mobile device (AMD) may perform tasks within a physical space. The AMD may move over ramps, bumps, or navigate around obstacles. The AMD may have an inertial measurement unit (IMU) and distance sensors. The IMU provides tilt information indicative of the AMD being on a flat surface or a ramp. The distance sensors provide information on distances between the AMD and surrounding obstacles. Using IMU measurements, the AMD determines a first speed limit that is safe given the tilt of the AMD. Using the distance sensors, the AMD determines a second speed limit that is safe given a distance to an obstacle. The AMD determines a maximum speed based on the first and second speed limits. Based on the maximum speed, the AMD determines whether to adjust a current speed and by how much.

摘要： According to an embodiment, a distance measuring device measures a distance to the measured object base on light scattered on the measured object is detected. The distance measuring device includes an optical detector and a measurer. The optical detector detects the scattered light. The measurer has a sampler to sample a signal corresponding to an output signal of the optical detector every time when the light is emitted at a plurality of sampling time points and a storage to accumulate sampling values and store an accumulation value at each sampling time point. The measurer measures the distance based on a plurality of accumulation values at the sampling time points.

摘要： A method of operating a coordinate measurement device includes selecting an operating mode on the coordinate measurement device. A first light is emitted from at least one light source of the coordinate measurement device. At least two angles associated with the emitting of the first light are measured. A second light is received with an optical detector of the coordinate measurement device. The second light is a reflection of the first light off of at least one of the retroreflector and the surface. A first distance is determined based at least in part on a mode of the coordinate measurement device that is selected, the emitting of the first light, and the receiving of the second light. Three dimensional coordinates of a point in the environment is determined based on the measuring of the at least two angles and at least one of the first distance and the second distance.

摘要： In one example, a LIDAR device includes a light sources that emits light and a transmit lens that directs the emitted light to illuminate a region of an environment with a field-of-view defined by the transmit lens. The LIDAR device also includes a receive lens that focuses at least a portion of incoming light propagating from the illuminated region of the environment along a predefined optical path. The LIDAR device also includes an array of light detectors positioned along the predefined optical path. The LIDAR device also includes an offset light detector positioned outside the predefined optical path. The LIDAR device also includes a controller that determines whether collected sensor data from the array of light detectors includes data associated with another light source different than the light source of the device based on output from the offset light detector.
