摘要： A blast hole measurement and logging apparatus, which generally comprises a housing configured to operatively house a solid-state LiDAR sensor array configured to transmit and steer pulses of light into a blast hole by shifting a phase of the pulses through the array to compile volumetric data of the sensor's field-of-view. Also included is a processor configured to receive the volumetric data from the LiDAR sensor, the volumetric data indicative of an internal volume of the blast hole which is useable in calculating an explosive charge according to a blast plan, the processor configured to store and/or transmit the volumetric data.

摘要： An image processor includes a map generator that generates a map being data including pixels each associated with depth-related information using an image captured with patterned light projected onto a target object, an edge detector that detects an edge of the target object using an image captured without patterned light projected onto the target object, and a corrector that corrects the map based on the detected edge to cause a discontinuous depth position to match a position of the edge of the target object.

摘要： An illustrative augmented reality (AR) management system determines a first optic parameter of a user corresponding to a first viewed point in a real-world environment and a second optic parameter of the user corresponding to a second viewed point in the real-world environment. The first viewed point and the second viewed point are viewed by the user as the user visually focuses on a target point in the real-world environment. The AR management system determines a depth value of the target point based on the first optic parameter and the second optic parameter, and creates an AR anchor associated with the target point based at least on the depth value. Corresponding methods and systems are also disclosed.

摘要： The present technology relates to a light-receiving element and a distance-measuring module. A light-receiving element includes an on-chip lens, a wiring layer, and a semiconductor layer arranged between the on-chip lens and the wiring layer, the semiconductor layer includes a first voltage application portion to which a first voltage is applied, a second voltage application portion to which a second voltage different from the first voltage is applied, a first charge detection portion arranged around the first voltage application portion, a second charge detection portion arranged around the second voltage application portion, and a pixel separation portion that separates the semiconductor layer at least up to a predetermined depth in a boundary portion of adjacent pixels, and a third voltage is applied to the pixel separation portion. The present technology can be applied to, for example, a light-receiving element that generates distance information by a ToF method.

摘要： Systems and methods are provided to analyze at least one sensor of a computing device to determine that the computing device is in a substantially flat position on the first surface, activate a camera comprising a depth sensor, and detect a second surface in a camera view of the camera. The computing device further analyzes pixel measurements from the depth sensor in a predefined area of the detected second surface to determine a minimum measurement of all of the pixel measurements in the predefined area of the detected surface, causes display of the minimum measurement from the first surface to the second surface overlaid on an image of the first and second surface in the camera view on a user interface of the computing device, and captures an image of the display.

摘要： The present disclosure describes approaches to camera re-localization that improve the accuracy of re-localization determinations by performing simulated consistency checks for three-dimensional maps. Client devices associated with users of a location-based application transmit image scans to a game server, which divides the received scan data into mapping sets used to generate 3D maps of environments and validation sets used to test the accuracy of the maps. To perform the testing, the game server identifies query scans in the validation set having GPS coordinates within a threshold distance of the mapped location and uses the 3D map of the environment to generate a pose estimate for each frame. The results of the localization queries are analyzed by comparing differences between the localization pose estimates and differences between the poses of independent pairs of frames in the query scan to evaluate the accuracy of the 3D map.

摘要： Embodiments of the disclosure provide a micro shutter array, an optical sensing system, and an optical sensing method. The optical sensing system includes a transmitter configured to emit an optical signal toward an environment surrounding the optical sensing system, and a receiver configured to receive the optical signal returning from the environment. The receiver further includes a condenser lens, a receiving lens, and a micro shutter array disposed between the condenser lens and the receiving lens. The condenser lens is configured to collimate the optical signal returning from the environment. The micro shutter array is configured to allow only a spatially-selected portion of the optical signal to pass through the micro shutter array at one time. The receiving lens is configured to receive and focus the spatially-selected portion of the optical signal on a photodetector of the receiver.
