Abstract: A maintenance support system prevents leakage of confidential information by excluding a maintenance target while imposing few restrictions on imaging conditions. A maintenance support system 100 includes a wearable terminal 1 including an imaging device 12, a first identifying device 31 configured to identify a first three-dimensional area TA including a maintenance target T with reference to a predetermined reference point M, and a second identifying device 32 configured to identify a mask pixel area excluding an effective pixel area corresponding to the first three-dimensional area for a captured image acquired by the imaging device in a post-movement state in which the wearable terminal has moved. A processed-image generating device 33 is configured to generate a processed image in which the mask pixel area is made invisible and a communication device 34 is configured to transmit the processed image to a support terminal 2.

Abstract: A maintenance support system includes a terminal including an imaging device, a device configured to identify a three-dimensional area TA including a maintenance target T with reference to a predetermined reference point, a device for identifying a position (vector A) of the imaging device in an initial state with respect to the reference point, a device for identifying a change of position (vector B) from the initial state of the imaging device, a device for identifying a position (vector C) of the reference point with reference to the imaging device in a post-movement state in which the terminal has moved, and identifying a pixel area corresponding to the three-dimensional area in a captured image, and a device for generating a processed image in which a portion other than the pixel area is made invisible. A communication device is provided for transmitting the processed image to a support terminal.
