摘　　要：针对目前苹果果实图像定位中存在的准确度较低、速度较慢等问题,在分析比较的基础上,对苹果果实定位方法进行了进一步的思考和研究。以3点确定圆算法为中心,配合图像中树枝树叶部分的分割、果实边缘的检测及去除图像的噪声等技术,以使处理速度满足实时要求,并使果实定位结果准确。经测试,本方法对成熟苹果果实具有较好的定位效果。Aimed at the low accuracy,slow speed problems existing in apple fruit image positioning,this paper made a further thinking and research on the methods of apple fruit's location. This research used three points to define a circle to make the processing speed meeting the demand of real- time and fruit being positioned precisely after division of leaves and branches in the image and detection of the edge of fruit and technology of getting rid of noise of image. After testing,the method had better effect on localization of mature apple fruit.
