To increase the measurement range of 3D microscopy, Scheimpflug adjustment, in which the imaging plane is tilted with respect to the telecentric lens plane, is often employed. However, the inclined imaging plane will introduce certain distortion to the captured image, which further affects the accuracy of the 3D reconstruction result. In this paper, a distortion model was derived based on the geometric optics theory. With it, the imaging distortion caused by the Scheimpflug condition can be effectively corrected. Experimental results will be presented to demonstrate the feasibility and validity of the proposed method.
为了扩大三维显微镜的测量范围，常采用倾斜校正（Scheimpflug adjustment），即成像平面相对于远心透镜平面倾斜。然而，倾斜的成像平面会给所采集的图像引入一定的畸变，进而影响三维重建结果的准确性。本文基于几何光学理论推导了一种畸变模型。利用该模型，可以有效校正倾斜校正条件引起的成像畸变。将给出实验结果以证明所提方法的可行性和有效性。
