An aspect of the invention is a map generation system including a three-dimensional data acquisition unit configured to acquire three-dimensional data from a scanning distance measurement sensor measuring a distance to a target to be measured, an operation information acquisition unit configured to acquire operation information representing an operation of a work machine occurring in a cycle of update of the three-dimensional data by the scanning distance measurement sensor, a correction amount calculation unit configured to calculate a correction amount of each measurement point of the three-dimensional data based on the operation information, and a correction processing unit configured to apply the correction amount to each measurement point of the three-dimensional data to correct the three-dimensional data.

Map generation system and map generation method

An aspect of the invention is a map generation system including a three-dimensional data acquisition unit configured to acquire three-dimensional data from a scanning distance measurement sensor measuring a distance to a target to be measured, an operation information acquisition unit configured to acquire operation information representing an operation of a work machine occurring in a cycle of update of the three-dimensional data by the scanning distance measurement sensor, and a three-dimensional data correction unit configured to remove a portion corresponding to the work machine in the three-dimensional data based on the operation information.

A posture acquisition unit acquires posture information of a bucket. A topography acquisition unit acquires topographical information indicating a three-dimensional shape of a construction target of a work machine. A projected image generation unit generates, based on the posture information and the topographical information, a projected image including a ground projection figure obtained by projecting teeth of the bucket on a ground surface of the construction target. A display control unit outputs a display signal for displaying the projected image.

Display control device, display control system, and display control method

A display system for a work machine includes an acquisition unit configured to acquire three-dimensional data of a plurality of measurement points, a conversion unit configured to convert the three-dimensional data into a vehicle body coordinate system, an image generation unit configured to generate a reference image representing a three-dimensional shape of a terrain based on the three-dimensional data converted into the vehicle body coordinate system, and a display processing unit configured to display the reference image on a captured image in a superimposed manner. The image generation unit decides a display form of the reference image at a position of the reference image corresponding to each measurement point depending on a distance of the measurement point in a normal direction with respect to a ground surface of the work machine.

Display system and display method

An image display system for a work machine including working equipment having a working tool and a turning body to which the working equipment is attached, includes: a position detector detecting at least one of an attitude and a position of the working equipment; a distance detector obtaining information on a distance from the work machine to a work target; and a processing device that generates, by using information on a position of the working tool obtained by the position detector and information on a position of the work target obtained from the information on the distance obtained by the distance detector, a first image including a portion corresponding to a part of the working tool and extending along a turning direction of the turning body, on the work target opposed to the working tool, and displays the first image on the display device.

Image display system for work machine

A display control system includes a work machine and a display control device. The work machine includes work equipment, a depth detection device configured to detect a depth in a detection range and provided at a position where the work equipment does not interfere with the detection range, and a posture detection device configured to detect a posture of the work machine. The display control device includes a map generation unit configured to generate a three-dimensional map representing a shape around the work machine based on depth information generated by the depth detection device and posture information generated by the posture detection device, a depth image generation unit configured to generate a depth image representing a depth of a range including a position of the work equipment in the three-dimensional map, and a display control unit configured to output a display signal to display the depth image.

Display control system, display control device, and display control method

A captured image acquisition unit acquires an image captured by an imaging device provided at a place of a work machine where a bucket is included in an imaging range. A posture acquisition unit acquires posture information of the bucket. A topography acquisition unit acquires topographical information indicating a three-dimensional shape of a construction target of the work machine. A projected image generation unit generates, based on the posture information of the bucket and the topographical information, a projected image obtained by projecting teeth of the bucket on the construction target. A display control unit outputs a display signal for displaying by superimposing the projected image on a place where at least the bucket appears, in the captured image.

Display control device and display control method

A display device has a display screen that displays a real image captured by an image capture device mounted in a construction machine which includes working equipment, and a combined image obtained by overlapping an object image indicating a virtual viewpoint image of an object around the construction machine viewed from a virtual viewpoint of an outside of the construction machine and a construction machine image indicating a virtual viewpoint image of the construction machine viewed from the virtual viewpoint, wherein the display device displays the combined image simultaneously with the real image in a partial region of the real image displayed in the display screen.

Display system, display method, and display device

A display system includes: a work machine image generation unit that generates, on the basis of detection data of a position of a work machine including working equipment and detection data of attitude of the work machine, a work machine image representing a virtual viewpoint image of the work machine viewed from a virtual viewpoint outside the work machine; a transport vehicle image generation unit that generates, on the basis of detection data of a position of a transport vehicle and detection data of attitude of the transport vehicle, a transport vehicle image representing a virtual viewpoint image of the transport vehicle viewed from the virtual viewpoint; a combining unit that generates a combined image in which the work machine image and the transport vehicle image are superimposed; and a display control unit that causes the combined image to be displayed on a display apparatus present outside the work machine.
