Abstract: A computing device includes: a three-dimensional (3D) sensor configured to capture point cloud data from a field of view (FOV); an auxiliary sensor configured to capture reference depth measurements corresponding to a surface within the FOV; a controller connected with the 3D sensor and the auxiliary sensor, the controller configured to: detect a reference depth capture condition; when the reference depth capture condition satisfies a quality criterion, control the auxiliary sensor to capture a reference depth corresponding to the surface within the FOV; and initiate, based on the captured reference depth, generation of corrective data for use at the 3D sensor to capture the point cloud data.

Abstract: A method for classifying depth scan data at a computing device includes: obtaining, at the computing device, a set of depth measurements and a graphical representation of the depth measurements; automatically selecting, at the computing device, a subset of the depth measurements indicating a region of interest; rendering, on a display of the computing device, an image including (i) the graphical representation of the depth measurements and (ii) a graphical indication of the region of interest overlaid on the graphical representation of the depth measurements; receiving, via an input device, a selection associated with the image; and generating a region of interest indicator based on the subset of the depth measurements and the selection.

Abstract: A method includes: monitoring sensor data including one or more representations of a treaded surface captured by a device; detecting, based on the sensor data, that the device has traversed a boundary of the treaded surface; in response to detecting that the device has traversed the boundary, determining a scan trigger point within the one or more representations; and generating a profile of the treaded surface from the one or more representations based on the scan trigger point.

Abstract: A method of detecting sensor obstructions in a computing device includes: at an emitter, emitting a beam of light through a scan window toward a treaded surface; at an image sensor, for a sequence of positions of the computing device along the treaded surface: capturing a sequence of images corresponding to the sequence of positions, each image in the sequence having a first region and a second region; wherein the first regions depict a first subset of reflections of the beam of light originating from a first depth range; and wherein the second regions depict a second subset of the reflections originating from a second depth range; at a controller: receiving the sequence of images; determining, based on the second regions, whether an intensity of the second subset of the reflections exceeds a occlusion threshold; and when the determination is affirmative, generating an alert indicating obstruction of the scan window.

Abstract: A method for dimensioning a target object includes: obtaining preliminary dimensioning data representing the target object; determining, based on the preliminary dimensioning data, a shape classification for the target object; when the shape classification for the target object is cuboidal, applying a cuboidal dimensioning function to the preliminary dimensioning data to obtain object dimensions; when the shape classification for the target object is non-cuboidal: selecting a non-cuboidal dimensioning function based on a preliminary bounding box of the target object detected in the preliminary dimensioning data; applying the non-cuboidal dimensioning function to obtain the object dimensions.
