Information processing device and information processing system

An information processing method comprising:

• an imaging step of imaging an interior of a machine tool;
• an image generation step of generating a mesh image obtained by partitioning at least a portion of imaged image data into a plurality of first mesh regions and a plurality of second mesh regions;
• a first identification step of identifying presence of a detection target from each of the first mesh regions of the mesh image;
• and
• even if the presence of the detection target has not been identified from the first mesh regions in the first identification step, a second identification step of identifying the presence of the detection target from each of the second mesh regions, the second mesh regions each having the same size as the first mesh regions, being shifted from the plurality of first mesh regions by a predetermined amount, and partially overlapping with the first mesh regions.

A machine tool system comprising:

• a machine tool having an interior and comprising a spindle in the interior rotatable about a major axis such that the spindle is configured for machining a workpiece in the interior, whereby chips from the workpiece are produced in the interior;
• a liquid discharger configured for discharging liquid for moving the chips produced as a result of machining by the spindle;
• an imaging unit for imaging the interior of the machine tool;
• and
• an information processing device configured to identify a presence of a detection target from image data from the imaging unit, the information processing device comprising a processor with a memory, the processor configured to perform tasks of:
• an image generation unit configured to generate a mesh image by partitioning at least a portion of the image data into a plurality of first mesh regions and a plurality of second mesh regions;
• and
• an identification unit configured to perform a first identification of the presence of the detection target from each of the first mesh regions of the mesh image,
• wherein the identification unit is further configured to, even if the presence of the detection target has not been identified from the first mesh regions in the first identification, perform a second identification of the presence of the detection target from the plurality of second mesh regions, the second mesh regions each having the same size as the first mesh regions, being shifted from the plurality of first mesh regions by a predetermined amount, and partially overlapping with the first mesh regions.
