METHOD FOR DETERMINING THE AREA OF ARBITRARY CLOSED PATTERNS

摘要

The invention relates to a television system for calculating the areas of arbitrary closed shapes. The purpose of the invention, - improve the accuracy of an arbitrary shape. The essence of the invention is, Thu of projected image of the object on the light-transducer signal image of the object moved along the surface of the light-transducer signal is converted into a video signal obtained image and determining the area of ​​any closed shape, when projecting an image of the object tsentIzobretenie relates to the instrumentation technology and robotics and can be used for calculating the space of arbitrary closed shapes. The purpose of the invention - an increase computing speed and the accuracy of determining the areas due to the possibility of reducing the increment angle of rotation of the image. 1 shows a graphical explanation of this method, where RI - distance from the reference center to the contour points; Figure 2 - a functional diagram of a device implementing the method The apparatus (2) comprises centering unit 1 septic image input 2 and output associated with the optical input unit 3 and the rotation image riruyut image of the object by aligning the center with the center of the object image centering reference block image, the object image is moved in increments of sample 2 l / N, is measured by the distance from the center of the object image to the contour image by counting pulses is calculated on the image area of ​​the sector EKTA formula 5sekt -kg-. The apparatus comprises a centering transfiguration with optical input, the image rotation unit, a line of photodetectors, consisting of photodetectors, a shift register, a pulse generator, a control input of the shift register, the reset shift register input, the control input calculating unit sector area delay element control counter input, a control input calculating unit, the adder. 2 yl.
