Method for guiding at assembly tail end based on machine vision

The invention discloses a method for guiding at an assembly tail end based on machine vision. The method comprises the following steps of: constructing and assembling a visual tail end navigation system; acquiring a regional binary image of a target regional image; filtering to obtain a target binary image; calculating to obtain a pixel position coordinate of the target binary image; and performing assembly navigation according to the offset distance, and correcting the navigation according to error analysis. According to the guiding method disclosed by the invention, autonomous navigation of assembly can be realized through a machine vision technical means, collection of scene information in the assembly process, extraction of target position pixel coordinates and calculation of offset, and terminal correction of navigation can be carried out, so that the assembly precision is effectively ensured. 本发明公开了一种基于机器视觉在装配末端进行引导的方法，步骤包括：构建装配视觉末端导航系统、获取靶标区域图像的区域二值图像、滤波获得靶标二值图像、计算获得靶标二值图像的像素位置坐标、获得物理长度与靶标二值图像的像素之间的转换对
