  • Patent number: 12093807
    Abstract: A neural network not requiring massive changes in configuration when changing the number of stages (number of levels) of the neural network. This neural network is provided with at least one neuron core 10 performing an analog multiply-accumulate operation and a weight-value-supply control unit 30 supplying the weight value to the neuron core 10. This neural network is subjected to control processing by a control-processor unit 40 controlling the supply of the weight value from said weight-value-supply control unit 30 in synchronization with the timing of the analog multiply-accumulate operation of the neuron core 10, and processing the data output from the neuron core 10 at every analog multiply-accumulate operation performed by said neuron core as serial data and/or parallel data.

  • Patent number: 9977983
    Abstract: A processing for specifying a correspondence relationship of feature points between two sets of optical data can be highly precise and efficiently carried out. The correspondence relationship of the perpendicular edges is obtained based on the assumption that the object is a building, in the processing for integrating the three-dimensional model obtained from the point cloud position data and the three-dimensional model obtained from the stereophotographic image. In this case, one perpendicular edge is defined by the relative position relationship with the other perpendicular edge, and the correspondence relationship is high-precisely and rapidly searched.
