  • Patent number: 11054802
    Abstract: A method for machining a workpiece by a numerical control (NC) machine constructs a model of a scene from one or multiple images including at least a part of the workpiece and a part of the NC machine and registers a model of the NC machine with the model of the scene to produce a first transformation between a coordinate system of the model of the scene and a coordinate system of the NC machine. The method also detects the workpiece in the model of the scene to produce a second transformation between the coordinate system of the model of the scene and a coordinate system of the workpiece and combines the first and the second transformations to register the coordinate system of the workpiece with the coordinate system of the NC machine. The registered workpiece is machined with a tool of the NC machine.

  • Patent number: 10909369
    Abstract: A method and system detects and localizes multiple instances of an object by first acquiring a frame of a three-dimensional (3D) scene with a sensor, and extracting features from the frame. The features are matched according to appearance similarity and triplets are formed among matching features. Based on 3D locations of the corresponding points in the matching triplets, a geometric transformation is computed. Matching triplets are clustered according to the computed geometric transformations. Since the set of features coining from two different object instances should have a single geometric transform, the output of clustering provides the features and poses of each object instance in the image.

  • Patent number: 10268201
    Abstract: A system controls motion of vehicle according to a first parking path ending at a target state and determines a second parking path from a current state to the target state using a model of the parking space. The system acquires images of the parking space during the motion of the vehicle along the first parking path and constructs the model of the parking space. The model is used to generate a set of virtual images of the environment of the parking space as viewed from virtual viewpoints outside of the first parking path. The current state of the vehicle is determined by comparing a current image of the parking space with at least one virtual image. The second parking path is determined from the current state to the target state.

  • Patent number: 10224137
    Abstract: There is provided an electromagnet control apparatus that continuously attracts crushed pieces of metals with the core of a magnetized electromagnet without immediately releasing the attracted pieces in a composite operation of a construction machine. The electromagnet control apparatus includes a control unit that controls a demagnetized state, a magnetized state, or a counter-magnetized state of an electromagnet. Until the end of a first threshold time tth1 from a transition to the demagnetized state from the magnetized state, the control unit ignores a turn-on voltage for turning on first transistors (a first transistor, a fourth transistor) and turns on the first transistors after a lapse of a second threshold time that is shorter than the first threshold time. The demagnetized state and the magnetized state are repeated until the end of the first threshold time tth1 from the transition to the demagnetized state.
