针对微操作系统中微操作工具相对于被操作对象Z方向精确定位难问题,提出了利用拟实环境辅助定位的方法,将定位问题转化为如何确定模糊图像模糊度问题。首先在拟实环境中精确定位,在实际操作中由高精度步进电机直接驱动操作臂使微操作工具到达被操作对象所处焦平面,既克服了“爬山”现象对定位精度的影响,又不受物镜景深的限制。
In order to solve the problem of precise positioning in the Z direction of the micromanipulation tools in the micromanipulation system, aiming at the problem of how to determine the ambiguity of the fuzzy image, aiming at the problem of precise positioning of the micromanipulator in the Z direction. First of all, accurate positioning in the real environment, in practice, the high-precision stepper motor drive arm directly to the micro-operation tool to reach the focal plane of the object being manipulated, not only to overcome the “climbing” phenomenon on the positioning accuracy, and Not limited by the objective depth of field.
