    Abstract: An artificial intelligence optical character image recognition system and method, using few shot learning on recognition system for character image in industrial processes, mainly including: preparing two or more identical neural network architecture units, inputting similar or different character images respectively, and comparing the calculation results to see if the weights are similar. If the similarity reaches the set standard value, they are classified as the same type of character, otherwise different. Through such procedures, training samples in the storage unit are gradually divided into settings of character sets with different contextual meanings, becoming a complete AI OCR system. It can increase training sample data by comparing characters, without increasing the training set. Simultaneously, it can improve the flexibility of recognizing test characters.

  • Patent number: 9651352
    Abstract: The invention discloses a method for roundness measurement, which includes the steps of, mounting and rotating an object on a rotary table; driving two measuring surfaces of two measurement units to respectively abut against two opposite sides of the object, wherein the two measurement units are disposed on two opposite sides of the rotary table and the two measuring surfaces are parallel to each other and perpendicular to a to surface of the rotary table; during rotation of the rotary table, measuring intermittently a shortest straight line distance between the two measuring surfaces and generating a variation data and after the rotary table completes a full-circle rotation, a processing unit receiving the variation data and generating measured data. The present invention also discloses a device for roundness measurement.

  • Patent number: 9653866
    Abstract: A real-time wavelength correction system for visible light is co-operated with an optical system to make a parallel light beam split into a zero-order diffractive parallel light beam and a first-order diffractive parallel light beam. The zero-order diffractive parallel light beam focuses on a first back focal plane to form a first light spot. A drift of the first light spot is applied to determine an angular drift of the parallel light beam. The first-order diffractive parallel light beam is focused on a second back focal plane to form a second light spot. A drift of the second light spot is applied to determine an angular drift of the first-order diffractive parallel light beam. The angular drifts of the parallel light beam and the first-order diffractive parallel light beam, which are changed with real time temperature variation, are applied to correct the wavelength of the parallel light beam.

  • Patent number: 9057608
    Abstract: A simple type dual axes optoelectronic level includes a carrier, an adjustable fixing mechanism, a level sensing device, a container cup holding a liquid, and a reflector. The adjustable fixing mechanism and the container cup are fixed at the carrier. The level sensing device is fixed at the adjustable fixing mechanism and faces the container cup. The reflector is fixed at the bottom surface of the container cup. The level sensing device provides a measuring light beam, which is refracted by the liquid surface to the reflector, and reflected back to the liquid surface by the reflector, and refracted again by the liquid surface to the level sensing device. Through the refraction effect, the level sensing device can detect two angles between the bottom surface of the carrier and the liquid surface. The dual axes optoelectronic level has advantages of simple structure, low cost and differentiating angles of two axes.
