Maintenance support system, maintenance support method, program, method for generating processed image, and processed image

A maintenance support method by use of a wearable terminal including an imaging device and worn by a maintenance worker, the maintenance support method comprising:

• a first identifying step of identifying a predetermined first three-dimensional area including industrial equipment which is a maintenance target and/or identifying a predetermined second three-dimensional area excluding the industrial equipment which is the maintenance target, by a first identifying device, with reference to a predetermined reference point in a captured image acquired by the imaging device in an initial state;
• a second identifying step of identifying a mask pixel area excluding an effective pixel area corresponding to the first three-dimensional area and/or identifying a mask pixel area corresponding to the second three-dimensional area, in the captured image acquired by the imaging device, by a second identifying device, in a post-movement state in which the wearable terminal has moved;
• a processed-image generating step of generating, by a processed-image generating device, a processed image, wherein the mask pixel area identified in the second identifying step is made invisible for the captured image acquired by the imaging device in the post-movement state;
• and
• a communication step of transmitting, by a communication device, the processed image generated in the processed-image generating step to a support terminal.
