摘要
[目的]探究拍摄高度对大米图像质量的影响。[方法]先对获取的大米图像进行分割,然后从分割图像中统计米粒数。在10种光照强度下,对3种拍摄高度进行试验。[结果]虽然从图像中统计的米粒数相同,但3种高度下大米图像的分割阈值存在差异。[结论]拍摄高度是大米图像中分割阈值的一个重要影响因素。
The shooting height is an important factor in rice text based on machine vision.The rice image is normal segmentated,and then the number of rice is obtained from segmentation image.The experiments include 10 different light intensities and 3 level heightens.It shows that the segmentation thresholdings are different in 3 different heightens through the number of rice obtained from images are same.So shooting height is an influence factor for segmentation thresholding in rice images.
