pcl（C++）批量读文件读到500多个时出现错误是怎么回事？求解答

[qq_45849742]

 会出现txt数据加载失败字样！

//主程序段
int main() {
    string FilePath = "E://dataprocessed//type1";//自己设置目录  
    string savepath = "E://dataprocessed//t2pcdtype1//";
    vector<string> FileName_List;

    string savename;

    //获取该路径下的所有文件  
    getFiles(FilePath, FileName_List);
    int number = FileName_List.size();
    for (int i = 0; i < number; i++)
    {
        cout << i << endl;
        const char* name = FileName_List[i].c_str();
        string I = to_string(i + 1);
        savename = savepath + "s1" + I + ".pcd";
        txt2pcd(name, savename);

    }
    return 0;

}
//txt转pcd段
void txt2pcd(const char* name, string savename)
{
    // 加载txt数据
    int number_Txt;
    FILE* fp_txt;
    tagPOINT_3D TxtPoint;
    vector<tagPOINT_3D> m_vTxtPoints;
    fp_txt = fopen(name, "r");

    if (fp_txt)
    {
        while (fscanf(fp_txt, "%lf %lf %lf %lf", &TxtPoint.x, &TxtPoint.y, &TxtPoint.z, &TxtPoint.l) != EOF)
        {
            m_vTxtPoints.push_back(TxtPoint);
        }
    }
    else
        cout << "txt数据加载失败！" << endl;
    number_Txt = m_vTxtPoints.size();
    pcl::PointCloud<pcl::PointXYZL> cloud;


    // Fill in the cloud data
    cloud.width = number_Txt;
    cloud.height = 1;
    cloud.is_dense = false;
    cloud.points.resize(cloud.width * cloud.height);


    for (size_t i = 0; i < cloud.points.size(); ++i)
    {
        cloud.points[i].x = m_vTxtPoints[i].x;
        cloud.points[i].y = m_vTxtPoints[i].y;
        cloud.points[i].z = m_vTxtPoints[i].z;
        cloud.points[i].label = m_vTxtPoints[i].l;
    }
    pcl::io::savePCDFileASCII(savename, cloud);
    std::cerr << "Saved " << cloud.points.size() << " data points to txt2pcd.pcd." << std::endl;
