Apparatus and method for measuring resolution of CCD camera base on triangle direction discrimination

InactiveCN101355711AEasy to testEliminate the largest sources of errorTelevision systemsTesting optical propertiesMeasurement deviceGrid pattern
The present invention relates to a CCD camera resolution measurement device based on triangle direction identification and a method thereof, belonging to the photoelectric test field. The device comprises a CCD camera to be measured, a resolution target, an even illumination lamp house and a high resolution monitor. The revolution target adopts an equilateral triangle pattern to substitute an ordinary grid pattern. In the test process, the identification of the orientation of the equilateral triangle substitutes the conventional fringe resolution so that the Morie fringe influence in the conventional grid pattern resolution test can be effectively avoided. The television line number corresponding to the correct decision probability higher than 75 percent is determined to be the limiting resolution of the camera. In order to improve the measuring accuracy, a value interpolation calculation is adopted for the standard grid interval so scheme out a novel television resolution target. The measurement accuracy can be largely improved by cooperating two targets. The method and the device can be applied to the performance evaluation of various visible light CCD cameras.
