Low resolution adaptive distance display

Guide systems for indicating a distance between a first object and a second object and a method for visually representing a distance between two objects as the distance reduces are provided. A sensor measures a distance between the first object and the second object. A processor receives a distance measurement from the sensor and determines whether the distance measured by the sensor is within one of a plurality of distance intervals. Upon determining that the distance is within one of the plurality of distance intervals, the processor displays a distance indicator on the display. The distance indicator is located on the display based on the distance according to a scale for the distance interval, where a display area on the display represents the distance interval. The scale for the distance intervals becomes finer as the distance between the first object and the second object decreases.

Feedlot bunk calling system and method

Aspects of the present invention include a feedlot bunk calling system comprising a mobile sensor arrangement comprising a ranging sensor unit, for generating a range signal indicative of a distance between the ranging sensor unit and a surface of feed within a feedlot bunk, and a positioning sensor unit, for generating a position signal indicative of a geospatial position of the mobile sensor arrangement. The system further comprises a computing module configured to generate an estimate or indication of an amount of feed in the feedlot bunk, based at least in part on the range signal and the position signal.

Estimation of spatial profile of environment

Disclosed herein is a system and method for facilitating estimation of a spatial profile of an environment based on a light detection and ranging (LiDAR) based technique. By repurposing the optical energy for communications needs, the present disclosure facilitates spatial profile estimation by optical means while facilitating free-space optical communication.

Geometric fingerprinting for localization of a device

Systems, apparatuses, and methods are provided for developing a fingerprint database for and determining the geographic location of an end-user device (e.g., vehicle, mobile phone, smart watch, etc.) with the database. A fingerprint database may be developed by receiving a depth map for a location in a path network, and then identifying physical structures within the depth map. The depth map may be divided, at each physical structure, into one or more horizontal planes at one or more elevations from a road level. Two-dimensional feature geometries may be extracted from the horizontal planes. At least a portion of the extracted feature geometries may be encoded into the fingerprint database. WO 2016/103028 PCT/IB2015/002511 Receiving a depth map for a location in a path network Identifying physical structures within the depth map Dividing the depth map, at each physical structure, into one or more horizontal planes at one or more elevations Extracting two-dimensional feature geometries from ...

Laser based speed and accident reconstruction measuring apparatus and method

System and method to reduce DVE effect on LIDAR return

SYSTEM AND METHOD TO REDUCE DVE EFFECT ON LIDAR RETURN A LIDAR system for vehicle operation that can operate in degraded visual environments (DVE) is described. The LIDAR system may use a spatial light modulator to find the phase conjugate of the DVE being traversed by the laser beam and cancel out the backscatter from the DVE, which allows the detection of extremely small numbers of directly reflected photons reflected by a target surface. If the target is not detected, the LIDAR is iteratively scanned to its maximum available depth of focus until the target is acquired. The LIDAR system is especially useful for autonomous landing of VTOL aerial vehicles in locations where the target landing spot is approximately known but cannot be directly visualized due to DVE media, such as smoke, dust, fog, or the like.
