Detailed Description

template<typename DataType>
struct toolbox::pcl::dsc3d_signature_t< DataType >

3D形状上下文描述子签名 / 3D Shape Context descriptor signature

Template Parameters

DataType

数据类型（float或double） / Data type (float or double)

3DSC描述子使用1980维直方图（11径向×12方位×15仰角）来描述局部3D形状 The 3DSC descriptor uses a 1980-bin histogram (11 radial × 12 azimuth × 15 elevation) to describe local 3D shape

// 基本使用 / Basic usage
dsc3d_signature_t<float> desc1, desc2;
 
// 计算距离 / Compute distance
float dist = desc1.distance(desc2);
 
// 用于KNN搜索 / For KNN search
std::vector<dsc3d_signature_t<float>> descriptors = {...};
bfknn_generic_t<dsc3d_signature_t<float>, DSC3DMetric<float>> knn;
knn.set_input(descriptors);
