通氣-
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
本文結合在研的tdiccd全景航空相機，用兩種不同的方法實現對像移速度公式的推導：坐標系變換法和正交投影解析法。 -
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
利用坐標系變換的方法可推出像面上各點的像移速度公式，該公式包含了幾乎所有的運動因素：飛機的前向飛行、飛機的姿態角變化、相機自身的擺掃運動等等，是精確的像移速度公式。本公式同樣適用於畫幅式航空相機和線陣ccd推掃型航空相機。 -
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
簡化后的像移速度公式在工程上容易實現，但是，在飛機姿態角不為零時，會產生像移誤差。本文通過舉例的方法，對這種誤差進行了定量的分析，指出這種誤差對像質的影響程度。 -
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導像移速度公式，忽略了飛機的姿態角的變化，認為飛機的姿態角為零，所以它是簡化的像移速度公式。 -
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
像移補償在工程實現時，經常採用簡化的像移速度公式。忽略了飛機初始姿態角的影響，這就必然帶來補償后的像移誤差。
