中文说明：SIFT特征点检测监测方法。具有对于图像平移、旋转和尺度变化不变性的优点，成为近十年来最流行的图像特征点检测方法，被广泛用于图像匹配、物体识别、分类等领域。本算法对图像预处理阶段的图像增强算法进行了改进，去除了原本的直方图均衡化图像增强算法，使得图像拼接时间缩短了近一倍，且图像拼接效果依旧良好
English Description：
SIFT feature point detection and monitoring method. It has the advantages of invariance to image translation, rotation and scale change, and has become the most popular image feature point detection method in recent ten years. It is widely used in image matching, object recognition, classification and other fields. This algorithm improves the image enhancement algorithm in the image preprocessing stage, removes the original histogram equalization image enhancement algorithm, reduces the image stitching time by nearly one time, and the image stitching effect is still good
