Examples
- Using orthogonal projective analytic method , the simplified formula of imv was deduced , ignoring the effect of aircraft ' s initial rotational angle , presuming the angle is zero
利用正交投影解析法推导像移速度公式，忽略了飞机的姿态角的变化，认为飞机的姿态角为零，所以它是简化的像移速度公式。 - The simplified formula of image motion velocity ( imv ) is usually introduced in engineering . the formula ignores the effect of aircraft ' s initial rotational angle , which will necessarily bring on the error of imc
像移补偿在工程实现时，经常采用简化的像移速度公式。忽略了飞机初始姿态角的影响，这就必然带来补偿后的像移误差。 - Combined with the reseaching panoramic aerial camera with tdi ccd , the paper deduced the formula of imv with two methods . one is coordinate system transformation method , the other is orthogonal projective analytic method
本文结合在研的tdiccd全景航空相机，用两种不同的方法实现对像移速度公式的推导：坐标系变换法和正交投影解析法。 - The simplified formula of imv is easily achieved in engineering . but it will bring on the error of imc , when the angles is nonzero . the paper quantitatively analysed the error with an example , and pointed out the effect of this error
简化后的像移速度公式在工程上容易实现，但是，在飞机姿态角不为零时，会产生像移误差。本文通过举例的方法，对这种误差进行了定量的分析，指出这种误差对像质的影响程度。 - Using coordinate transformation method , the formula of imv on every point of image plane was deduced , and it included almost all motorial factors : the flight velocity of aircraft , roll , pitch , yaw , camera ' s scan and so on . thus , it is a precise formula , and it is also applied to frame cameras and push _ room cameras with array ccd
利用坐标系变换的方法可推出像面上各点的像移速度公式，该公式包含了几乎所有的运动因素：飞机的前向飞行、飞机的姿态角变化、相机自身的摆扫运动等等，是精确的像移速度公式。本公式同样适用于画幅式航空相机和线阵ccd推扫型航空相机。
