摘　　要：随着数码相机的普及和升级,高成像质量的非量测数码相机用于无人飞行器遥感已经成为现实。目前研究和应用中,变焦相机仅当作定焦相机使用,没有充分发挥其变焦的作用。文中通过利用OpenCV对两款变焦相机进行标定,分析变焦相机不同焦距的使用特点,总结变焦相机内参数与焦距之间的关系,为充分发挥变焦相机的作用提供一定的依据。As the prevalence and upgrade of digital cameras, it is realized that high quality non--metric digital cameras used in UAVs remote sensing. In current researches and applications, zoom cameras are generally used as those with fixed lens, that is to say, we don＇t make the best use of the zoom function, and it is a waste of the equipment. Through calibrating two zoom cameras using OpenCV, this paper analyses the characteristics of different focuses, summarizes the relationships of interior parameters with focuses, and provides evidence for making the best use of zoom cameras.
