Splet21. apr. 2013 · 1 Look at the documentation for matchFeatures. There are many options to tweak. The default matching 'Method' is 'NearestNeigborRatio', so the main knob there is the 'MaxRatio' parameter. Increasing its value will give you more matches. Also, a lot depends on what interest point detector and what feature descriptor you are using.

SpletMultiple features in features1 can match to one feature in features2. When you set Unique to true , the function performs a forward-backward match to select a unique match. After matching features1 to features2, it matches features2 to features1 and keeps the best match. Output Arguments collapse all SpletThe typical approach is to use the complete point cloud for registration. Build a Map from Lidar Data (Automated Driving Toolbox) example uses this approach for map building. This example uses distinctive features extracted from the point cloud for map building.

Splet最近，我使用matlab从图像中提取SURF特征点，然后在匹配时在matlab中使用matchFeatures函数. 由于我是一支彩色笔，因此阅读帮助文档有些困难，并且大多数搜索都包含在其中. matlab的cv软件包中的功能与内置功能非常不同. SpletYou can perform this task by using the extractFPFHFeatures function to extract the features and the pcmatchfeatures function to find matching features between both of the point clouds. The pcmatchfeatures documentation contains an example that shows you how to perform this. 2 件のコメント表示 1 件の古いコメント Koushik Maturi 2024 年 11 月 10 日
