Abstract: A state data acquisition unit acquires state data indicating a state of a work machine at a plurality of times. A work determination unit determines a classification of a work of the work machine for each of the plurality of times based on the acquired state data. A period determination unit determines a start point and an end point of a period related to a predetermined classification among determined classifications of works. An index-value determination unit obtains an index value of the state of the work machine from the start point to the end point.

Abstract: A control apparatus for work machines includes a position designation reception unit configured to identify designation of a position with respect to a state image displayed on a display panel and a screen control unit configured to perform screen control according to an image displayed at the position that has been identified, among partial images constituting parts of the state image.

Abstract: A work analysis device includes a state data acquisition unit state, a work specification unit, and an output unit. The data acquisition unit acquires state data indicating a state of a work machine. The work specification unit specifies, based on the acquired state data, a classification of work of the work machine for each of the multiple times, and collects the classification of work in a chronological order. The output unit outputs a time series of the specified classification of work.

Abstract: A reproduction device includes an acquisition unit, a reception unit, and a reproduction unit. The acquisition unit acquires log information including angle information of a movable part of a work machine. The log information is associated with time. The reception unit receives a reproduction instruction usable to reproduce a movement of the work machine. The reproduction unit reproduces the movement of the work machine by sequentially applying the angle information to a work machine model upon receiving the reproduction instruction.

Abstract: In the image processing system according to the present invention, the data acquisition unit acquires a captured image showing a loading/unloading target of a transporting material of a work machine. The area-specifying unit specifies an area including the loading/unloading target from the captured image. The loading/unloading target-specifying unit specifies at least one predetermined surface of the loading/unloading target from the area including the loading/unloading target.

Abstract: A reproduction device includes an acquisition unit, a reception unit, a reproduction unit, and an estimation unit. The acquisition unit acquires log information of a work machine, which is associated with time. The reception unit receives a reproduction instruction for an operation of the work machine. The reproduction unit reproduces the operation of the work machine, by sequentially applying angle information of the work machine that is included in the log information, to a work machine model in a case of receiving the reproduction instruction. The estimation unit estimates a work content of the work machine at each time, based on the log information.

Abstract: A state data acquisition unit acquires state data indicating a state of a work machine at a plurality of times. A work determination unit determines a classification of a work of the work machine for each of the plurality of times based on the acquired state data. A period determination unit determines a start point and an end point of a period related to a predetermined classification among determined classifications of works. An index-value determination unit obtains an index value of the state of the work machine from the start point to the end point.

Abstract: A transport object specifying device of a work machine includes an image acquisition unit, a drop target specifying unit, a three-dimensional data generation unit, and a surface specifying unit. The image acquisition unit acquires a captured image showing a drop target of the work machine in which a transport object is dropped. The drop target specifying unit specifies a three-dimensional position of at least part of the drop target based on the captured image. The three-dimensional data generation unit generates depth data, which is three-dimensional data representing a depth of the captured image, based on the captured image. The surface specifying unit specifies a three-dimensional position of a surface of the transport object in the drop target by removing, from the depth data, a part corresponding to the drop target based on the three-dimensional position of the at least part of the drop target.

Abstract: A work analysis device includes a state data acquisition unit state and a work specification unit. The data acquisition unit is configured to acquire state data indicating a state of a work machine. The work specification unit is configured to, based on the acquired state data, specify a classification of a unit work that indicates work carrying out one work goal for the work machine, and specify a classification of an element work. The element work constitutes the unit work, and indicates a series of actions or work classified by purpose.
