The content creation system comprises: an operation measurement devicethat acquires, as measurement information, a three-dimensional work operation of a model worker Rthat performs the work of the work procedure; an evaluation criterion creation devicethat creates evaluation criterion information on the work of the work procedure, based on the measurement information of the three-dimensional work operation; and a content creation devicethat creates and updates the training content, based on the measurement information of the three-dimensional work operation, the evaluation criterion information and the three-dimensional shape information of the work target device. The work management servercreates the evaluation criterion information, based on distance information of the three-dimensional work operation with respect to the three-dimensional shape in specific stage of the work procedure, on the condition that a predetermined body motion of the model worker Ris detected.

Content creation system

A content presentation system includes: a trainee terminal that presents training content to the trainee; a worker terminal used by a worker; a tool recognition device that acquires a work video of the worker and recognizes the tool being used by the worker; a determination device that determines success or failure of the work at a specific stage based on the information about the work tool recognized by the tool recognition device; and a content creation device that creates and updates the training content based on the determination result of the determination device. When the determination result is determined to be the failure of the work by the determination device, the content creation device identifies a portion of the training content corresponding to the specific stage in the work procedure and updates the portion of the training content so as to suppress a factor of the failure.

Content presentation system and content presentation method

A content presentation system includes: a training content distribution functionthat presents the training content to the trainee; a work content delivery functionthat presents a work procedure based on augmented reality; a user operation detection unitthat detects a three-dimensional operation of the site worker; a work record analysis functionthat determines success or failure of the work based on the evaluation reference information; and a content creation/updating functionthat updates the training content based on the determination result. When a predetermined body motion of the worker is detected, the work record analysis function determines whether the work has failed based on the measurement information of the model worker up to the body motion. When the work is determined to have failed, the content creation/updating function updates the training content so as to suppress the factor of the failure.

The present invention relates to an aircraft-utilizing deterioration diagnostic system and provides a technique capable of improving diagnostic efficiency and accuracy when comparing the previous and current aerially-photographed images to diagnose a deteriorated state of a target. The diagnostic system includes: a drone(aircraft) configured to be navigated along a route around a targetand having a cameraconfigured to photograph the target; and a computer (PCand server) configured to control navigation of the aircraft and photographing by the camera. The computer is configured to: acquire data from the aircraft including an image group obtained by consecutively photographing the targetfor each predetermined date and time; based on diagnostic data including a diagnostic image group photographed at a current date and time, reference data including a reference image group of a previous date and time, associate, for the same target, images including the same portion as comparison target images; compare the previous image and the current image among the comparison target images to detect a deteriorate portion; and provide a screen converted and visualized for the user such that the deteriorated portion in the image is plotted on the three-dimensional model of the target.

Aircraft-utilizing deterioration diagnosis system

As a technology for preventing the leaking of confidential information more properly, provided is a work recording apparatus including: a recording control unit configured to record a work situation; a position detection unit configured to detect a position; and a usable function restriction unit configured to specify an applicable predetermined state through use of the position detected by the position detection unit and restrict a part or all of functions of the recording control unit based on the specified applicable predetermined state.

Work recording apparatus, system, program, and method preventing confidential information leaks

Provided is a technology for supporting work carried out under a unique work environment. A work management apparatus includes: an image reception unit configured to receive an image from another apparatus; an instruction target specification unit configured to specify a device instructed by a predetermined instruction method in the received image; and a display instruction unit configured to instruct the another apparatus to display the device specified by the instruction target specification unit in a different display mode from a display mode of another device contained in the image.

Work management apparatus, work defect prevention program, and work defect prevention method

A photovoltaic inspection system is provided, the photovoltaic inspection system detecting a failure by eliminating ON/OFF operation of a switch or others at the time of inspection or checkup as much as possible, reducing an influence of a temperature distribution as a whole with a small effort, and detecting a local deterioration in a photovoltaic module or string. According to a typical embodiment, in a photovoltaic system having a plurality of photovoltaic strings formed of one or a plurality of photovoltaic modules arranged to be aligned, a photovoltaic inspection system which detects the failure in the photovoltaic strings includes: a current detector which measures each of a first output current of a first photovoltaic string and a second output current of a second photovoltaic string; and a monitoring unit which calculates a second temperature property of the second photovoltaic string based on a value of the first output current and a value of the second output current and which determines whether the second photovoltaic string has the failure or not based on the second temperature property.
