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： In one aspect of the teachings herein, a 3D imaging apparatus uses a “texture tool” or facilitates the use of such a tool by an operator, to add artificial texture to a scene being imaged, for 3D imaging of surfaces or background regions in the scene that otherwise lack sufficient texture for determining sufficiently dense 3D range data. In at least one embodiment, the 3D imaging apparatus provides for iterative or interactive imaging, such as by dynamically indicating that one or more regions of the scene require artificial texturing via the texture tool for accurate 3D imaging, and then indicating whether or not the addition of artificial texture cured the texture deficiency and/or whether any other regions within the image require additional texture.
