Mobile work analysis device and work analysis method

A work analysis method executed by a mobile computer including an image-capturing unit configured to capture an image of a work and record a work moving image that is a moving image of the work, the mobile computer being configured to record the work moving image and perform work analysis based on the work moving image, and being portable during a work that includes a plurality of work processes in order to capture an image of a work of each of the work processes, the work analysis method comprising:

• receive input of a user operation and set a temporal boundary for each work element on the work moving image recorded by the image-capturing unit,
• detect recognition information by which the temporal boundary between a work of a first work process and a work of a second work process that is subsequent to the first work process in the work is recognized, the recognition information being provided on a work place of each work process,
• when the recognition information is detected, set the temporal boundary on the work moving image between work elements that are the work of the first work process and the work of the second work process, based on the recognition information,
• designate a type including at least one of a valid operation indicating that a valid operation has been performed in the work and an invalid operation indicating that an invalid operation has been performed in the work relative to each of the work elements defined by setting the boundary,
• calculate a work time of the work of the work process and/or the work element based on the work moving image on which the boundary is set;
• acquire attribute information of a worker of the work of the work process and/or the work element based on the work moving image on which the boundary is set;
• store work-related data in which at least the work moving image of the work and/or the work element, the work time, the attribute information of the worker, and the recognition information detected by the boundary detection unit are associated with each other for each work of the work process and/or each work element;
• and
• store the work element for which the type is designated.

A mobile work analysis device comprising:

• an image-capturing unit configured to capture an image of a work and record a work moving image that is a moving image of the work,
• wherein the mobile work analysis device is configured to record the work moving image and perform work analysis based on the work moving image, and
• during a work that includes a plurality of work processes, the mobile work analysis device is portable in order to capture an image of a work of each of the work processes,
• the mobile work analysis device further comprising:
• at least one processor configured to
• receive input of a user operation and set a boundary for each work element on the work moving image recorded by the image-capturing unit;
• detect recognition information by which a boundary between a work of a first work process and a work of a second work process that is subsequent to the first work process in the work is recognized;
• when the recognition information is detected, set the boundary on the work moving image between work elements that are the work of the first work process and the work of the second work process, based on the recognition information;
• designate a type including at least one of a valid operation indicating that a valid operation has been performed in the work and an invalid operation indicating that an invalid operation has been performed in the work for each of the work elements defined by setting the boundary by the first boundary setting unit and the second boundary setting unit;
• calculate a work time of the work of the work process and/or the work element based on the work moving image on which the boundary is set;
• acquire attribute information of a worker of the work of the work process and/or the work element based on the work moving image on which the boundary is set;
• and
• store work-related data in which at least the work moving image of the work and/or the work element, the work time, the attribute information of the worker, and the recognition information detected by the boundary detection unit are associated with each other for each work of the work process and/or each work element;
• and
• a storage unit configured to store the work element for which the type is designated by the type designation unit.
