摘　　要：为研究图像拼接时两幅图像中重复部分大小对拼接效果及扩展的视角范围的影响,对影响拼接的重复信息量进行量化,并提出通过对拼接图进行分割后的结果来评价拼接是否理想.实验结果表明,图像重复信息量占原图比例约为1/4以上时图像组能获得理想的田间拼接图像,为农药喷洒自动化中针对整个地块作出合理喷洒决策提供研究基础.Image stitching is necessary due to the limited coverage area of single field image. And the size ot repeated part of two images will affect mosaic result. In this paper, the repeat area is quantified. The evaluation method of mosaic result is put forward. We judge whether the object is beneficial recognition after segmentation of mosaic image. The experimental results show that ideal mosaic image can be obtained when the ratio of repeat area accounts for more than a quarter of the original image. This will provide research foundation for making reasonable decision of the automation pesticide spraying for the whole plot.
