激光散斑成像技术在医学和生物等领域得到广泛应用,照射对象内部变化可以产生动态变化的散斑图像。利用待测对象内部的散射粒子的动态变化与激光散斑变化的对应关系,结合激光散斑的统计学特性模拟相应算法,通过图像处理技术分辨出待测对象内部的动态变化程度。农作物种子内部粒子的活跃程度体现种子的活力,所以可以通过激光散斑技术的这个特点结合种子自身特性来分辨出作物种子的活力区域与非活力区域。
Laser speckle imaging technology is widely used in medical and biological fields, and the internal changes of the irradiated object can produce speckle images with dynamic changes. According to the corresponding relationship between the dynamic changes of scattering particles and the laser speckle in the test object, the corresponding algorithms are simulated by the statistical characteristics of the laser speckle, and the dynamic changes of the object to be measured are distinguished by the image processing technology. The activity of seeds in crop seeds reflects the vitality of seeds. Therefore, this feature of laser speckle detection can distinguish the vitality and non-viability of crop seeds by combining the characteristics of seeds.
