Input Arguments

collapse all

File name, specified as a character vector or string scalar. The input file type must be a PLY or PCD format file.

For a PLY-file, the pcwrite function converts an organized M-by-N-by-3 point cloud to an unorganized M-by-3 format. It converts the format because PLY files do not support organized point clouds. To preserve the organized format, you can save the point cloud as a PCD-file.

If you do not specify the file name with an extension, the function writes the file in a PLY-format.

Object for storing point cloud, specified as a pointCloud object.

PLY or PCD formatted file, specified as the comma-separated pair consisting of 'Encoding', and either 'ascii', 'binary', 'compressed' for the file format.

File FormatValid Encodings
PLY'ascii', 'binary'
PCD'ascii', 'binary', or 'compressed'
