摘要
由于物体表面的反光率具有随机性,在单色相干光照明下CMOS图像传感器上呈现的图像包含了随机噪声。应用统计方法可以有效去除随机噪声的影响,通过最小二乘法拟合重新生成曲线,此方法在实际应用中达到了预期的效果。
Due to the randomness of reflective rate on the surface of the object.The image of CMOS image sensor contains the random noise under monochromatic coherent light illumination.The application of statistical method can effectively remove the influence of random noise, the curve is regenerated by the Least Squares Method Fitting, this method reaches the expected results in practical application.
