Determination of interactions with predefined volumes of space based on automated analysis of volumetric video

A method performed by one or more computers, each computer having at least one processor and a memory, the method comprising:

• receiving image data comprising multiple images of a physical industrial environment captured over one or more periods of time by one or more cameras;
• processing the image data to create a static 3D model representing stationary structure in the environment;
• processing the image data to create a dynamic 3D model representing one or more moveable objects in the environment over time;
• providing a user interface through which a user can view and control a visual perspective of a replay of the dynamic 3D model over time visually superimposed on the static 3D model;
• receiving from the user through the user interface a specification of one or more virtual spatial interaction sensors, wherein each virtual spatial interaction sensor is defined by a point or volume of space within the environment;
• displaying to the user in the user interface a visual depiction of each point or volume of space within the environment defining the one or more virtual spatial interaction sensors superimposed on a visual depiction of the static 3D model in a visual perspective;
• and
• analyzing a portion of the dynamic 3D model to identify intersections between the one or more moveable objects and the one or more virtual spatial interaction sensors over time.
