本文根据误差理论讨论了摄影物镜的畸变测量方法的精度,把径向畸变测量误差的理论计算值与实测值比较,结果是符合的。据此,可以用理论值判断实测值的可靠性。分析表明测量长主距和小视场角相机的畸变,必需使用较高测长和测角精度的仪器;测量短主距和大视场相机的畸变,可使用精度较低的测长和测角仪器。
According to the theory of error, this paper discusses the accuracy of the measurement method of the photographic lens aberration, and compares the theoretical calculation value of the radial distortion measurement error with the measured value. The result is in line with this. Accordingly, the theoretical value can be used to judge the reliability of the measured value. Analysis shows that measuring the long primary distance and small field of view of the camera distortion, the need to use a higher measuring length and angle accuracy of the instrument; measurement of short main distance and large field of view camera distortion, the use of less accurate length and angle measurement instrument.
