	<span style=\"line-height:1.5;\">针对靶场高速电视测量系统短焦距大视场的特点，分析了畸变对测量精度的影响；考虑到靶场短焦距光学系统畸变难以克服的问题，采用实验法和图像矫正法，利用视场标校数据、基于最小二乘原理，建立了三次方程拟合的数学模型，对光学系统全视场进行了畸变校正。实验结果表明，该方法能够有效提高短焦距大视场光学系统靶场测量的精度，简便实用，可操作性强。<br />
Aiming at the characteristical of short focal length and large view field of high-speed TV mea-surement system in shooting range, the influence of optical system distortion on measurement accuracy is analyzed. Considering that the optical distortion is difficult to overcome, the mathe-matical model of cubic equation fitting is established by experiment and image correction, using field of view calibration data and least square principle, and the distortion correction of optical full field of view is carried out. The results show that this method can effectively improve the optical measurement accuracy of short focal length and large field of view in shooting range, which is simple, practical and operable.</span><span style=\"line-height:1.5;\"></span>
