  • Patent number: 12292508
    Abstract: Provided are a processing apparatus and a point cloud elimination method that can suppress point cloud processing load even if the number of points included in point clouds increases due to realization of high resolution of an apparatus that acquires point clouds of an object. The processing apparatus includes a memory (storage apparatus) and a processor. The memory stores data of a point cloud of an object. The processor eliminates data of a second point (subject point) that is included in the point cloud and is next to a first point (previous point) that is included in the point cloud from the data of the point cloud when the difference between the distance to the first point and the distance to the second point is smaller than a threshold (first threshold Th1) (Step 1903: YES) (Step 1908).

  • Patent number: 12291848
    Abstract: A main valve throttle (53) of a main valve (43) is configured by a lateral hole (53A) communicating an inlet side flow passage (25) and an outlet side flow passage (27) through the inside of the main valve (43) and a groove portion (53C) communicating the inlet side flow passage (25) and the outlet side flow passage (27) via an outer peripheral portion of the main valve (43). The groove portion (53C) is located such that a hydraulic fluid spurting from the groove portion (53C) changes the direction of a flow of a hydraulic fluid spurting from the lateral hole (53A). In this case, the direction of a flow of a hydraulic fluid F2 spurting from the lateral hole (53A) can be changed to approach the direction parallel to the center axis of the main valve (43) by a hydraulic fluid F1 spurting from the groove portion (53C).
