| 摘要: | 提出了一种标定光学显微镜图像失真的方法, 该方法利用一块高精度的光栅作为参考, 用显微镜拍摄光栅作为变形栅, 使用加窗傅里叶几何相位分析法求解光栅形变, 得到显微镜镜头畸变场. 仿真结果表明了该方法的可行性. 最后对KEYENCE VHX-1000型数码显微镜放大100~500倍时的镜头畸变进行了标定. |
| Abstract: | This paper proposes a method to calibrate the image distortion of an optical microscope. By employing a high-precision grating as a reference, this method uses the microscope to shoot the grating as the deformed grating, and uses the windowed Fourier geometric phase analysis method (WFT-GPA) to solve the grating deformation, and finally obtains the distortion field of the microscope lens. Simulation results verify the feasibility of the method. Finally, the lens distortion of the KEYENCE VHX-1000 digital microscope at 100- 500 times magnification is calibrated. |
