Avoid open3d Read IO return

szx · May 20, 2020, 4:45pm

Hi

I use open3d (io.read_pointcloud) to load a list of pcds (>100) from a directory.

For each point cloud reading, open3d automatically return “Format=pcd, Extension=auto” in console. Because there are large number of pcd files needs to be loaded, and printing to console reduces the processing speed.

I am wondering if we can remove such automatically returned values. I am using Python and Open3d 0.9.0.

Any comment is appreciated

Thanks for the report, it is due to these lines that weren’t cleaned up:

github.com

intel-isl/Open3D/blob/master/src/Open3D/IO/ClassIO/PointCloudIO.cpp#L93


                bool remove_infinite_points,
                bool print_progress) {
std::string filename_ext;
if (format == "auto") {
    filename_ext =
            utility::filesystem::GetFileExtensionInLowerCase(filename);
} else {
    filename_ext = format;
}


std::cout << "Format = " << format << std::endl;
std::cout << "Extension = " << filename_ext << std::endl;


if (filename_ext.empty()) {
    utility::LogWarning(
            "Read geometry::PointCloud failed: unknown file extension.");
    return false;
}
auto map_itr =
        file_extension_to_pointcloud_read_function.find(filename_ext);
if (map_itr == file_extension_to_pointcloud_read_function.end()) {

It will be removed soon.
