Research in vision systems applied to manufacturing processes has increased during the last years. Nevertheless, accurate positioning systems frequently require costly investments. This article presents a new algorithm developed in LabVIEW for controlling a novel positioning system that processes images to obtain the position, which could be implemented in micromachining. With this aim, the method uses the analysis of the LEDs shown in an image projected on an LCD screen to perform an accurate positioning. The ultimate goal of this method is to get the coordinates of the images shown on the screen in order to know the movement made by the system and, in this way, be able to compensate the error. The experimental results and related analysis developed proved the accuracy and consistency in dissimilar situations. In addition, once implemented the algorithm proposed in a closed loop program, a positioning system is achieved where the error is always convergent.

近年来，对应用于制造过程的视觉系统的研究有所增加。然而，精确的定位系统经常需要昂贵的投资。本文介绍了在LabVIEW中开发的一种新算法，用于控制一种新颖的定位系统，该系统可以处理图像以获得位置，可以在微加工中实现。出于此目的，该方法使用投影在LCD屏幕上的图像中显示的LED的分析来执行准确的定位。该方法的最终目标是获取屏幕上显示的图像的坐标，以便了解系统的运动，并以此方式来补偿误差。实验结果和相关分析结果证明了在不同情况下的准确性和一致性。此外，
