feature point selection

基本解释

Random block feature point selection is developed to avoid feature point close clustering.
为了避免特征点选取相对集中，给出一种随机分块选取特征点对的方法。
And, many researches were concentrated on the point of feature selection and classification algorithm.
其中，诸多研究集中在特征选取和分类算法上。
Finally, space parameter measurement method based on feature point selection was designed to accurately measure the distance, angle and volume of cutting motor structure.
最后，设计出基于特征点拾取的空间参数测量方法，实现剖切后发动机结构空间距离、角度和体积的精确测量。
