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.

Image processing system, image processing method, learned model generation method, and data set for learning

A measurement system includes an imaging unit mounted to a swing body of a work machine to image a shape around the work machine, a position detection unit which determines a position of the swing body, an imaging unit position calculation unit which calculates a position of the imaging unit when the imaging unit performs imaging while the swing body swings, and a three-dimensional position calculation unit which determines a three-dimensional position around the work machine during the imaging, on the basis of a position of the imaging unit calculated by the imaging unit position calculation unit.

Measurement system, work machine, and measurement method

An image processing system includes a data acquisition unit and a position specifying unit. The data acquisition unit acquires a captured image showing a drop target of a work machine in which a transport object is dropped. The position specifying unit specifies a position of a predetermined part of the drop target shown in the captured image based on the captured image and a position specifying model. The position specifying model is a trained model, which outputs a position of a predetermined part of a drop target shown in an image when the image is input. A display device may display information regarding the position of the predetermined part of the drop target of the transport object specified by the image processing system.

A work machine measurement system includes an image acquisition unit that acquires an image of a work target captured, while a swinging body of a work machine is swinging, by an image capturing device mounted on the swinging body, a three-dimensional position calculation unit that calculates a three-dimensional position of the work target based on the image, a swing data acquisition unit that acquires swing data about the swinging body, a determination unit that determines whether or not the swing data satisfies a predefined swinging condition and an output unit that outputs a swinging instruction signal based on a result of the determination by the determination unit.

Work machine measurement system, work machine, and measuring method for work machine

An image pick-up apparatus includes a first stereo camera attached to a revolving unit and a second stereo camera attached to the revolving unit. The first stereo camera picks up an image of a first image pick-up range. The second stereo camera picks up an image of a second image pick-up range above or beyond the first image pick-up range.

Image pick-up apparatus

A capture data-receiving unit receiving first capture data captured by an image-capturing device, which is included in a work vehicle, capable of generating three-dimensional data, a display unit displaying the first capture data received by the capture data-receiving unit, and an acquisition instruction-transmitting unit transmitting an acquisition instruction for causing the work vehicle to acquire second capture data captured by the image-capturing device and used for generation of three-dimensional data are included.

Terminal device, control device, data-integrating device, work vehicle, image-capturing system, and image-capturing method

A first stereo camera has a first image pick-up portion and a second image pick-up portion arranged on the right side of the first image pick-up portion in a lateral direction of a vehicular main body. A second stereo camera has a third image pick-up portion and a fourth image pick-up portion arranged on the right side of the third image pick-up portion in the lateral direction of the vehicular main body. The first image pick-up portion and the third image pick-up portion constitute a left image pick-up portion group. The second image pick-up portion and the fourth image pick-up portion constitute a right image pick-up portion group. The left image pick-up portion group and the right image pick-up portion group are arranged at a distance from each other in the lateral direction of the vehicular main body.

A shape measuring system includes an object detection unit attached to a work machine and configured to detect an object and output information of the object, a shape detection unit configured to output shape information representing a three-dimensional shape of the object by using the information of the object detected by the object detection unit, and an information providing unit configured to attach time information for specifying the shape information to the shape information and output the shape information.

Shape measuring system and shape measuring method

A position measurement system includes: at least a pair of imaging devices mounted on a work machine; a calculation unit provided at the work machine and configured to perform stereo measurement by using information of an image of an object captured by at least the pair of imaging devices; and a determination unit configured to determine condition related to image capturing by the imaging device based on a performance result of the stereo measurement.

Position measurement system and position measurement method

A calibration method includes: detecting a predetermined position of a work machine according to first and second methods in a different posture of the work machine; and obtaining a conversion information item used to convert a position detected by the first method from a coordinate system in the first method into a coordinate system different from that of the first method or obtaining a conversion information item used to convert a position detected by the second method from a coordinate system of the second method into a coordinate system different from that of the second method by using a first position information item as information for the predetermined position detected by the first method and a second position information item as information for the predetermined position detected by the second method in a posture of the work machine when the predetermined position is detected by the first method.
