摘　　要：提出了一种应用概率统计细分提高测长仪器分辨率的方法。将概率统计细分法扩展到图像测量中 ,对被测量图像施加一种随空间变化的扰动 ,可使图像法测量尺寸及瞄准被测物的分辨率显著提高。实验结果表明 ,这种细分方法的非线性误差小于像素当量的 5% 。This paper advances a method using the probability statistical sub division to improve resolution power of length meter.When the probability statistical sub division method is expanded in image measurement,the resolution power between the image measuring dimensions and aiming at the measured objects can be greatly improved only in the case of the images to be measured by a disturbance added with a changing space.The experiment proves that the non linear error of this sub division method is less than 5% of a pixel equivalence,and that the resolution power is raised by 1～2 quantity grades with the variations in measuring conditions.
