Document Type and Number:
Japanese Patent JP2812958
Kind Code:
B2
Abstract:
PURPOSE:To learn teacher data to measure, recognize, and display an object with a high precision by obtaining information related to the existence, the position, and the shape in accordance with the acoustic pressure and the phase of a scattered wave and inputting this information to a neutral net and expressing it on a three-dimensional lattice of the object to obtain teacher data of the neural net. CONSTITUTION:A stationary cosine wave is inputted to an ultrasonic sound wave transmitter 2 from a quadrature phase oscillator 4 of an object recognizing device, and an object 1 is irradiated with the stationary ultrasonic wave from the sound wave transmitter 2, and the scattered wave from the object 1 is measured by ultrasonic receivers 3 arranged in an array. A complex detecting circuit 5 refers to the cosine wave and the sine wave sent from the oscillator 4 to detect information observed by receivers 3 and transfers separated acoustic components and phase components to a neural net 6. Learning is performed in the neural net 6 by sent information and teacher data to recognize the existence, the position, and the shape of the object 1, and results are displayed on a display device 7, thus measuring the existence, the position, and the shape of the three-dimensional object with a high precision.
