将PCD文件转化为PLY格式输出（QT+PCL）

环境

ubuntu 14.04
Qt 5.2.1
PCL 1.7

剩下的话不多说，直接放代码

pcd2ply.pro

QT       += core

QT       -= gui

TARGET = pcd2ply
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

INCLUDEPATH +=  \

return -1;
}

writer.write(output_filename, cloud, Eigen::Vector4f::Zero(), Eigen::Quaternionf::Identity(),true,true);
return 0;

}

int main(int argc, char *argv[])
{
       string input_filename = "/home/**/****.pcd";
       string output_filename = "/home/**/****.ply";

    PCDtoPLYconvertor(input_filename , output_filename);

}
