JPS644871A - Different kind light source illuminance difference stereo image recognizing device - Google Patents

Abstract

PURPOSE:To exactly execute an image input in a short time by executing a detection with the sensitivity of three different frequencies by a color TV camera, separating and calculating the reflection intensity of an illumination from three directions by the same image, and determining an extended Gaussian space of an object. CONSTITUTION:The titled different kind light source illuminance difference stereo image recognizing device consists of three light sources 3-5 for radiating on an object from three parts being different, respectively, and having different colors, respectively, a color TV 2, a decoder 2, a decoder 6, an A/D converter 7, an image memory 8, and a CPU 9 executes a detection with the sensitivity of three different frequencies by the color TV camera 2, separates and calculates the reflection intensity of an illumination from three directions by the same image, and limits an extended Gaussian space of the object. As for an image obtained by the color TV camera 2, a signal is separated into each three primary color by the decoder 6, and this signal is digitized by the A/D converter 7, and stored in an image memory 8. This stored image is processed by the CPU 9, and the object 1 is recognized stereoscopically. In such a way, flickering of the illumination and an input operation of three times of the image are unnecessary, therefore, the image can be recognized at a high speed.
