INTEGRATION OF OPTICAL AREA MONITORING WITH INDUSTRIAL MACHINE CONTROL

摘要

An industrial safety system is provided that integrates optical safety monitoring with machine control. The safety system includes an imaging sensor device supporting pixel array processing functions that allow time-of-flight (TOF) analysis to be performed on selected portions of the pixel array, while two-dimensional imaging analysis is performed on the remaining portions of the array, reducing processing load and response time relative to performing TOF analysis for all pixels of the array. The portion of the pixel array designated for TOF analysis can be pre-defined through configuration of the imaging sensor device, or can be dynamically selected based on object detection and classification by the two-dimensional imaging analysis. The imaging sensor device can also implement a number of safety and redundancy functions to achieve a high degree of safety integrity.

1. An optical safety system, comprising:
a memory that stores computer-executable components; a processor, operatively coupled to the memory, that executes the computer-executable components, the computer-executable components comprising:
a pixel array component configured to, for one or more pixel arrays of one or more images of a hazardous industrial area captured by one or more imaging sensor devices, group pixels of the one or more pixel arrays to yield a subset of the pixels on which two-dimensional (2D) analysis is to be performed;an image analysis component configured to perform 2D analysis on the subset of the pixels;a distance determination component configured to perform 3D analysis on point cloud data received from the one or more imaging sensor devices; anda hazard analysis and decision component configured to classify a first object in the image as motorized industrial equipment and a second object in the images as a human based on results of the 2D analysis and the 3D analysis, to correlate the results of the 2D analysis and the 3D analysis to yield correlated information relating to a relationship between the human and the motorized industrial equipment, and to generate a control output that controls the motorized equipment based on the correlated information.
