Abstract: At least some embodiments are directed to systems and methods to optimize relative signal delays in vision systems having illumination assemblies separate from a host. In an example embodiment there is a system that includes a host device having, an imaging assembly coupled to the host device and operable to capture image data, and an illumination assembly coupled to the host device and operable to provide illumination. The system is configured such that the host transmits, to the imaging assembly, a series of exposure signals causing the imaging assembly to capture a series of frames and transmits, to the illumination assembly, a series of illumination signals causing the illumination assembly to provide the illumination as a series of strobes. Thereafter the host evaluate each frame to identify a peak-brightness frame and from that, based on a corresponding illumination signal, determines an appropriate relative signal delay for future operations.

Abstract: A method in an imaging controller of detecting depth sensor artifacts includes: obtaining, from first and second sensors, first and second pluralities of points defined by respective (i) planar positions and depths in a common frame of reference, and (ii) scan angles relative to field of view centers of the first or second sensors; for each of a subset of candidate points from the first plurality of points: searching the second plurality of points for a validator point having (i) a planar position within a threshold distance of a planar position of the candidate point, and (ii) a scan angle smaller than a scan angle of the candidate point; responsive to identifying the validator point: when the depth of the validator point exceeds the depth of the candidate point, classifying the candidate point as an artifact.

Abstract: Provided herein is a device and method for improved operating of cameras and light sources of a mobile automation apparatus. Light sources are operated to periodically provide illumination light for a camera operating according to a given exposure time and frequency, with a pulse duration having a respective frequency that is an integer multiple of the camera frequency, and higher than a threshold frequency where successive activations of the light sources are imperceptible. Furthermore, a light source paired with a camera is located at a distance from the paired camera that illuminates an object imaged by the paired camera, and where parasitic reflections from the paired light source are not reflected into the paired camera.

Abstract: A method and apparatus for performing a variable data capture process at a data capture device comprising a data capture module and a trigger mechanism is provided. In operation, the data capture device detects an initial activation of the trigger mechanism. In response to the activation, data capture is initiated at the data capture module. A continued activation of the trigger mechanism subsequent to the initial activation is also detected. Following the detection of the continued activation of the trigger mechanism, the device identifies an obtained gesture and performs a data capture operation based on the identified gesture.

Abstract: A method for controlling an alternative motion-based user interface in a device comprising a projector is provided. The method comprises receiving, at the device, an input comprising an instruction to switch from a previous user interface to the alternative user interface. The device then generates an image containing a plurality of selectable elements and a pointing element, and projects the image on a surface with the projector. The device detects a movement of the device, and updates the image to stabilize the plurality of selectable elements against the detected movement and to track the detected movement with the pointing element. The device projects the updated image on the surface, and selects one of the selectable elements based on a motion vector of the pointing element relative to the selectable elements. The device performs an action corresponding to the selected one of the selectable elements.
