The image features of object and ambiance in the real robot visual servo system are analyzed . the method of object recognition based on image segmentation and corner detection is presented . an image is segmented into several regions by image segmentation 分析了实际的机器人视觉系统中目标物体以及环境的图像特征，提出基于图像分割与角点检测的物体识别方法，通过图像分割将整幅图像分割为一个个的单一物体区域，分别利用角点检测，找出与模板角点信息相匹配的区域，然后利用基于模糊自适应操作算子遗传算法的图像匹配方法寻求最优匹配。
