タプルのベクトルを作成しようとしていますが、このベクトルを関数から戻そうとしていますが、エラーが多数発生しています。引数としてpcl :: PointCloudColorHandlerをタプルに渡します。具体的には、関連するエラーは次のとおりです。boost :: shared_ptrにvalue_typeという名前の型がありません
error: no type named 'value_type' in 'boost::shared_ptr<pcl::visualization::PointCloudColorHandlerRGBField<pcl::PointXYZRGB> >'
私の質問は、なぜこの動作は許可されていないのですか？ここに私のコードは次のとおりです。
std::vector<std::tuple<std::string, pcl::PointCloud<pcl::PointXYZRGB>::ConstPtr>, pcl::visualization::PointCloudColorHandlerRGBField<pcl::PointXYZRGB>::Ptr > Map::getCloudColoredReal(){
std::vector<std::tuple<std::string, pcl::PointCloud<pcl::PointXYZRGB>::ConstPtr, pcl::visualization::PointCloudColorHandlerRGBField<pcl::PointXYZRGB>::Ptr > changed_clouds;
try{
for(int i = 0; i < addedFiles.size(); i++){
if(associatedClouds.find(addedFiles[i].getPCDFileName()) != associatedClouds.end()){
pcl::PointCloud<pcl::PointXYZRGB> cloud(associatedClouds.find(addedFiles[i].getPCDFileName())->second);
pcl::PointCloud<PointXYZRGBAI> cloudInfo(masterClouds.find(addedFiles[i].getPCDFileName())->second);
for(int j = 0; j < cloud.points.size(); j++){
uint32_t red = (cloudInfo.points[j].rgba >> 16) & (0x0000ff);
uint32_t green = (cloudInfo.points[j].rgba >> 8) & (0x0000ff);
uint32_t blue = (cloudInfo.points[j].rgba) & (0x0000ff);
cloud.points[j].r = red;
cloud.points[j].g = green;
cloud.points[j].b = blue;
}
pcl::PointCloud<pcl::PointXYZRGB>::ConstPtr constCloud(&cloud);
pcl::visualization::PointCloudColorHandlerRGBField::Ptr rgbHandler(&constCloud);
std::tuple<std::string, pcl::PointCloud<pcl::PointXYZRGB>::ConstPtr, pcl::visualization::PointCloudColorHandlerRGBField<pcl::PointXYZRGB>::Ptr > tup = std::make_tuple(addedFiles[i].getPCDFileName(), constCloud, &rgbHandler);
changed_clouds.push_back(tup);
}
}
}
catch(std::exception& e){
std::cout << "Color Mode not set to real." << std::endl;
}
return changed_clouds;
}
全エラー：

はどうもありがとうございました。
に変更しなければならない問題を軽減しようとすると、例えばタプルのベクトルを使って実験する。表示されていないインスタンス化コード（ 'clouds_in_map'）は関連しているかもしれません。私はここに何も見ない、申し訳ありません。 –
