Detailed Description

template<typename DataType, class Derived>
struct toolbox::pcl::base_signature_t< DataType, Derived >

描述子签名的基类 / Base class for descriptor signatures

该类定义了所有描述子签名类型的通用接口，主要提供距离计算功能。 This class defines the common interface for all descriptor signature types, mainly providing distance calculation functionality.

Template Parameters

DataType	数据类型（如float或double） / Data type (e.g., float or double)
Derived	派生的签名类型 / Derived signature type

// 自定义描述子签名示例 / Custom descriptor signature example
struct my_signature_t : base_signature_t<float, my_signature_t> {
    std::array<float, 128> histogram;
    
    float distance_impl(const my_signature_t& other) const {
        float dist = 0;
        for (size_t i = 0; i < 128; ++i) {
            dist += std::abs(histogram[i] - other.histogram[i]);
        }
        return dist;
    }
};
