Abstract: A microscopic image fusion method based on region growing judges the fuzzy degree of the microscopic image and determines the fuzzy seed block by evaluating the definition of every image block in the microscopic image. Then, the fuzzy region and clear region are exactly segmented by region growing and are marked. Finally, a clear and high-quality microscopic image, fused by a plurality of microscopic images, is obtained. Due to the combination of the definition evaluation of the microscopic image, and segmentation of the fuzzy region and clear region by region growing, the fusion results of the microscopic image of the present invention show great advantages at the subjective human perception and the objective evaluation. Furthermore, the present invention has simple calculation and stable result, is easy to be implemented and adapted for fusing the digital optical microscopic images which are shot by shallow depth of field.

Abstract: The present invention discloses a microscopic three-dimensional measurement system and method based on a moving diaphragm. The present invention adds the diaphragm into the existing optical microscopic imaging system to limit light irradiation angle during imaging for reducing the diameter of blur circle, which extends the depth of field and the depth measurement range, so as to achieve the three-dimensional measurement of large-size objects to be measured. Through changing the position of the added diaphragm, two images with different light incident directions are obtained, which is similar to binocular stereo vision, and then the disparity map is used to predict the depth, so as to carry out the 3D scene reconstruction. Since the depth of field of the imaging system is enlarged and the imaging model has certain non-linear characteristics, the present invention uses quadratic function to express the non-linearity, which reduces the measurement error.
