  14. Image motion compensation ( imc ) is the key technology of high - resolution space camera. image motion speed is seperated into two vectors in image coordinate for the existence of the drift angle : the forward direction image motion speed and the crosswise image motion speed. in fact, drift angle control eliminates the crosswise image motion speed, so it is a part of image motion compensation

    在空間照相，由於偏流角的存在，使得像移速度在像面坐標系存在兩個分量：前向像移速度和橫向像移速度，偏流角控制本質上是消除橫向像移速度，因此，偏流角控制是空間相機像移補償的一部分。
