输入：

自拍两幅同一个场景(或物体)的角度/远近有差别的图像

（对于学有余力的同学，建议多测试几张角度/远近差别较大的图像）

任务：

在每张图像中检测特征点位置并将匹配画出匹配得最好的10-20对特征点

输出要求（以下三个结果分别输出，不要重叠在一张图上）：

1. 在两张图上分别画出检测到的特征点位置

2. 对匹配得最好的10-20对特征点：每对特征点对用连接线画出

3. 用椭圆形式在图上画出上述每个特征点的描述子方向与尺度等信息

编程工具：

Visual C++/Visual Studio，OpenCV

提示-Input: self-timer two same scene (or object) angle/distance difference image (For students there is spare capacity, the proposed multi-test a few angle/distance difference larger image) task: each image detection the location of the feature points and match draw match best 10-20 on the output requirements of feature points (three results output, do not overlap in a diagram): 1. draw detected respectively in the two graphs the orientation and scale of the feature point position 2 of the best match 10-20 to feature points: each pair of feature points to draw the connecting lines 3. using elliptic form shown in diagram of each of said feature point descr iptor and other information programming tools: Visual C++/Visual Studio, OpenCV Tip
