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

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 display system includes: an image data acquisition unit that acquires a front image and a side image captured by an imaging device mounted on a work machine having a swing body swinging about a swing axis and working equipment supported by the swing body, the front image including at least an image in a front direction with respect to the swing axis, the side image including at least an image in a lateral direction to the swing axis, the lateral direction being orthogonal to the front direction; and a display control unit that displays the front image and the side image acquired by the image data acquisition unit on a display device existing outside the work machine.

Display system, display method, and remote control system

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.

It is possible to inspect scratches and staining on a wafer surface on the basis of an LPD map obtained from a particle counter, by providing a meansfor detecting aggregation of clustered point defects (LPD) from two-dimensional distribution informationfor such fine LPD on the surface of a silicon wafer, and an improvement in the inspection efficiency and the precision of judgements of 'defective' status can be achieved. Furthermore, the system is devised so that the trend of generation of scratches and staining in a specified process can easily be detected by accumulating wafer surface information such as scratch information, staining information and the like for the wafer surface detected by a wafer surface inspection device(especially as image information or numerical information), and superposing sets of information thus accumulated. Plans for improving processes can be made by both the wafer supplier and wafer consumer by sharing such information with both parties.

Apparatus for inspecting wafer surface, method for inspecting wafer surface, apparatus for judging defective wafer, method for judging defective wafer, and apparatus for processing information on wafer surface

In a laser marking method for making a dot mark on a semiconductor wafer by using laser beam, molten splashes which arise at the laser marking are prevented from adhering to a surface of the wafer and a shape of the dot mark is kept in a stable posture with its visibility being ensured even after the marking made throughout various and multistage steps in a manufacturing process by the semiconductor apparatus. The method comprises forming a transparent thin film on at least a dot mark-formation area of a semiconductor wafer body of the wafer; irradiating the dot mark-formation area with laser beam having a wavelength selected in advance, on the transparent thin film; melting and deforming the wafer body by the laser beam transmitting the transparent thin film to form a dot mark; and by utilizing the heat generated when the wafer body is melted, deforming the transparent thin film, along with the deformation of the dot mark, into the same shape as the dot mark without a breakdown of the transparent thin films.
