Abstract: A LIDAR unit includes a housing defining a cavity. The LIDAR unit further include a plurality of emitters disposed on a circuit board within the cavity. Each of the emitters emits a laser beam along a transmit path. The LIDAR system further includes a first telecentric lens assembly positioned within the cavity and along the transmit path such that the laser beam emitted from each of the plurality of emitters passes through the first telecentric lens assembly. The LIDAR further includes a second telecentric lens assembly positioned within the cavity and along a receive path such that a plurality of reflected laser beams entering the cavity pass through the second telecentric lens assembly. The first telecentric lens assembly and the second telecentric lens assembly each include a field flattening lens and at least one other lens.

Abstract: A system can use semantic images, lidar images, and/or 3D bounding boxes to determine mobility parameters for objects in the semantic image. In some cases, the system can generate virtual points for an object in a semantic image and associate the virtual points with lidar points to form denser point clouds for the object. The denser point clouds can be used to estimate the mobility parameters for the object. In certain cases, the system can use semantic images, lidar images, and/or 3D bounding boxes to determine an object sequence for an object. The object sequence can indicate a location of the particular object at different times. The system can use the object sequence to estimate the mobility parameters for the object.

Abstract: A distance measuring device is disclosed that includes a controller operably coupled with a receiver to receive different amplification channels. The controller includes a time of flight core configured to determine time of flight information for the light pulse; and a decider block configured to determine a measurement correction value for the device based on a determination of a presence of a reflective background that is different than a measurement correction value selected for the device when there exists a diffuse background or an absence of a background into a reading field.

Abstract: One example system comprises a LIDAR sensor that rotates about an axis to scan an environment of the LIDAR sensor. The system also comprises one or more cameras that detect external light originating from one or more external light sources. The one or more cameras together provide a plurality of rows of sensing elements. The rows of sensing elements are aligned with the axis of rotation of the LIDAR sensor. The system also comprises a controller that operates the one or more cameras to obtain a sequence of image pixel rows. A first image pixel row in the sequence is indicative of external light detected by a first row of sensing elements during a first exposure time period. A second image pixel row in the sequence is indicative of external light detected by a second row of sensing elements during a second exposure time period.

Abstract: An example of a problem to be solved by the present invention is to specify an influence on a distance measurement property of an attached-matter formed on an emission window of a distance measurement apparatus. A distance measurement apparatus (10) of the present invention is an apparatus that emits light output from a light source (14) through a transmissive member (20) and detects reflection light from a target object. The distance measurement apparatus (10) includes a light receiving unit (180) and an information generation unit (121). The light receiving unit (180) receives at least internal reflection light including reflection light reflected by the transmissive member (20). The information generation unit (121) generates information on the distance measurement property of the distance measurement apparatus (10) by using a light reception result of the internal reflection light by the light receiving unit (180).

Abstract: A light detection and ranging (LIDAR) system includes an optical circuit configured to generate a first transmitted optical beam and a second transmitted optical beam being frequency modulated with sweeps being divisible into multiple sub-sweeps over respective sub-bands of the frequency band, one or more receivers configured to produce a simultaneous measurement of a first beat frequency and a second beat frequency for each sub-sweep of the respective sub-band of the frequency band from return signals, and a signal processor. The signal processor is configured to determine a range and a velocity of a target from the simultaneous measurement and determine a custom sub-band size for a custom sub-sweep within the sweep. The signal processor is further configured to produce an additional simultaneous measurement of the beat frequencies based on the custom sub-sweep and determine an additional value of the range and the velocity from the additional simultaneous measurement.
