Basically this is a way to introduce n-D histogram descriptorsĪt each point, and treating them as a single contiguous block of memory. ForĮxample, x data usually has 1 element, but a feature descriptor like the

U - represents unsigned types uint8 ( unsigned char), uint16 ( unsigned short), uint32 ( unsigned int)ĬOUNT - specifies how many elements does each dimension have. I - represents signed types int8 ( char), int16 ( short), and int32 ( int) TYPE - specifies the type of each dimension as a char. SIZE - specifies the size of each dimension in bytes.

Graphics and computational geometry communities in particular, have created PCD is not the first file type to support 3D point cloud data. Support some of the extensions that PCL brings to n-D point cloud processing. The PCD file format is not meant to reinvent the wheel, but rather toĬomplement existing file formats that for one reason or another did not/do not
