Integration of optical area monitoring with industrial machine control
First Claim
1. An optical safety system, comprising:
- a memory that stores executable instructions; and
a processor, communicatively coupled to the memory, that executes or facilitates execution of the executable instructions to at least;
capture image data representing an industrial area;
classify a first object represented in the image data as industrial equipment and a second object represented in the image data as a human based on a first result of a first type of analysis performed on a first subset of pixels of the image data and a second result of a second type of analysis performed on a second subset of the pixels;
correlate the first result and the second result to yield correlated information relating to a relationship between the human and the industrial equipment; and
control an output signal that controls the industrial equipment based on the correlated information.

Abstract
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.

10. A method for controlling industrial equipment, comprising:
-
recording, by a safety system comprising at least one processor, image data representing an industrial area; classifying, by the safety system, a first object recorded in the image data as an industrial machine and a second object recorded in the image data as a human based on a first result of a first type of analysis performed on a first subset of pixels of the image data and a second result of a second type of analysis performed on a second subset of the pixels; correlating, by the safety system, the first result and the second result to yield correlated information defining a relationship between the human and the industrial machine; and controlling, by the safety system, an output signal that controls the industrial machine based on the correlated information. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable medium having stored thereon instructions that, in response to execution, cause a system comprising a processor to perform operations, the operations comprising:
-
collecting image data representing an industrial area; classifying a first object recorded in the image data as industrial equipment and a second object recorded in the image data as a human based on a first result of a first type of analysis performed on a first subset of pixels of the image data and a second result of a second type of analysis performed on a second subset of the pixels; generate correlated information based on one or more correlations between the first result and the second result, the correlated information defining a relationship between the human and the industrial equipment; and controlling an output signal that controls the industrial equipment based on the correlated information. - View Dependent Claims (20)
