An operation recognition system including an object to be operated, at
least one camera, a processor, and a controller. At least one camera is
configured to acquire image data of an operator in a predetermined period
of time, and a processor is configured to perform recognition processing
on the acquired image data. Upon processing the image data, the processor
is configured to define a virtual plane in between the object to be
operated and the operator. The processor is configured to then perform a
process to determine if a predetermined part of the operator penetrates
the virtual plane based on the recognition processing. Based on this
determination, the controller is configured to control the object to be
operated.
