摘要:

摘要机器人视觉伺服问题是当今国内外研究的热点问题之一,其研究成果不仅能够应用于工业生产,如上料、下料、搬运、喷涂、点焊、精密装配、质量检验等,而且能够促进各项相关学科的发展。本文通过分析研究典型关节型机器人视觉伺服系统的结构,针对系统中的关键技术——图像矩特征提取及基于图像矩特征的视觉伺服控制器设计作了一定的理论研究和分析,并在此基础上构建了典型关节型机器人视觉伺服仿真系统模型,设计了相应的软件算法,具体内容如下:(1)介绍了当前机器人视觉伺服系统的分类和机器人视觉伺服技术的发展概况并引入了机器人运动学模型和视觉系统成像模型;给出了不同坐标系间的位姿、位姿变化率的变换关系及机器人雅可比矩阵;在...
