摘要： Various embodiments of a laser scanner apparatus (10) and a method (1400) of operating a laser scanner apparatus (10), as disclosed herein, include the use of a variably blocked aperture (46) or a controlled defocusing in relation to receiving backscattered light (18). One or more embodiments combine both variable blocking and defocusing and may use a lens design that complements the blocking and defocusing. Among the various advantages offered by one or more embodiments disclosed herein is a laser scanner apparatus (10) that exhibits a flatter response curve to backscattered light (18) over a defined range of distances. That is, among other advantages of the configurations and operating methods disclosed herein, a laser scanner apparatus (10) experiences less variation in the optical power delivered to its photodetector (54) arrangement, in relation to detecting an object at different distances within a defined range.

摘要： A laser scanner apparatus (10) emits a laser pulse (14) and monitors for pulse reflections, with the relative timing of a reflected pulse (18) detected by the apparatus (10) being translated into an object distance according to Time-of-Flight (ToF) measurements performed by the apparatus (10). According to an example configuration or an example method (900) of operation, the apparatus (10) adjusts its ToF determination for reflected pulses (18) that are characterized as merged pulses formed by two or more overlapping reflected pulses (18). Among other advantages, the adjusted ToF determination yields a more accurate distance determination with respect to the earliest-arriving one(s) among the overlapping reflected pulses (18).

摘要： According to one aspect of the teachings presented herein, a machine vision system includes one or more sensor units that are each advantageously configured to use different pairings among a set of spaced-apart image sensors, to provide redundant object detection for a primary monitoring zone, while simultaneously providing for the detection of objects that may shadow the primary monitoring zone. Further, a plurality of "mitigations" and enhancements provide safety-of-design and robust operation. Such mitigations and enhancements include, for example, bad-pixel detection and mapping, cluster-based pixel processing for improved object detection, test-image injection for fault detection, dual-channel, redundant processing for safety-critical object detection, temporal filtering to reduce false detections, and the use of high dynamic range (HDR) images, for improved operation over variable ambient lighting conditions.

摘要： The teachings herein provide a method and apparatus for detecting erroneous pixel addressing in an imaging sensor. The method and apparatus advantageously use the characteristic "fixed pattern noise" of the sensor to detect addressing errors. Broadly, pixel addressing errors are detected based on comparing the pattern noise seen in data read outs from a targeted row or column of the sensor with characteristic fixed pattern noise known for the sensor.

摘要： According to one aspect of the teachings presented herein, a projective volume monitoring apparatus is configured to detect objects intruding into a monitoring zone. The projective volume monitoring apparatus is configured to detect the intrusion of objects of a minimum object size relative to a protection boundary, based on an advantageous processing technique that represents range pixels obtained from stereo correlation processing in spherical coordinates and maps those range pixels to a two-dimensional histogram that is defined over the projective coordinate space associated with capturing the stereo images used in correlation processing. The histogram quantizes the horizontal and vertical solid angle ranges of the projective coordinate space into a grid of cells. The apparatus flags range pixels that are within the protection boundary and accumulates them into corresponding cells of the histogram, and then performs clustering on the histogram cells to detect object intrusions.
