  • Publication number: 20240104891
    Abstract: In the object detection device, the plurality of object detection units output a score indicating a probability that a predetermined object exists, for each partial region set with respect to image data inputted. The weight computation unit computes a weight for each of the plurality of object detection units by using weight computation parameters and based on the image data. The weights are used when the scores outputted by the plurality of object detection units are merged. The weight redistribution unit changes the weight for a predetermined object detection unit, among the weights computed by the weight computation unit, to 0 and output the weights. The merging unit merges the scores outputted by the plurality of object detection units for each of the partial regions, by using the weights computed by the weight computation unit and including the weight changed by the weight redistribution unit.

  • Patent number: 11941562
    Abstract: Based on operation trajectory data an operation analysis device identifies all open points indicating positions at which the crusher is opened during the operation period and all close points indicating positions at which a crusher is closed during an operation period, calculates, as a shortest distance, a distance between each open point of the all open points and a close point nearest to the each open point, and identifies, as a sorting destination open point, an open point at which the shortest distance exceeds a first threshold value, identifies data until the crusher grasping the dismantling part moves to the sorting destination and returns to the dismantling target again from among the operation trajectory data as movement data of the crusher having moved in the dismantling operation, and identifies data in which the movement data has been removed from the operation trajectory data as grasping operation data.
