The invention discloses a flexible plate vibration form visualization method based on vision. A flexible plate vibration device is included, the flexible plate vibration device comprises a flexible plate, the flexible plate is provided with mark points, a binocular vision measurement unit is arranged in front of the flexible plate, the mark points and the flexible plate are within the view field range, and the binocular vision measurement unit shoots images containing the mark points and the flexible plate and inputs the images into a computer; the computer processes the acquired image based on an OpenCV visual library, and then interpolation is carried out based on a cubic spline function and a grid division algorithm to obtain more reference points; and each frame of vibration state of the flexible board is drawn based on the OpenGL graphics library to realize vibration form visualization of the flexible board. 本发明公开了一种基于视觉的柔性板振动形态可视化方法，包括柔性板振动装置，所述柔性板振动装置包括柔性板，所述柔性板设置标志点，所述柔性板的前方设置双目视觉测量单元，标志点及柔性板在其视野范围内，双
