  <dc:description>Data Organization
Under the root directory for the whole acquisition, there is a positions.csv file and 3 subdirectories: img, dense, and sparse. The mobile mapping 3D dataset was generated walking around an indoor space and each &lt;positionID&gt; corresponds to a unique pose along the trajectory of this motion. This version of the dataset contains a total of 99 unique poses. There is a separation of 1 meter between each adjacent pose.

positions.csv


	File format: One ASCII file.
	File structure Rows: Each image is one record.
	File structure Columns: Comma separated headers, with exact order described below.
	
		Filename, column 0: Panorama file name as on disk, without file extension.
		Timestamps, column 1: Absolute time at which the panorama was captured, Decimal notation, without thousands separator (microseconds).
		X,Y,Z, columns 2 through 4: Position of the panoramic camera in decimal notation, without thousands separator (meters).
		w,x,y,z, columns 5 through 8: Rotation of the camera, quaternion.
	
	


sparse


	Set of equirectangular rendered depth images.
	1920x960 resolution
	16-bit grayscale PNG
	White → 0 m
	Black → ≥ 16 m or absent geometry
	Occlusions: If a pixel was hit by several rays, only the value of the closest one is represented. 


dense


	Set of equirectangular rendered depth images.
	1920x960 resolution
	16-bit grayscale PNG
	White → 0 m
	Black → ≥ 16 m or absent geometry
	Occlusions: If a pixel was hit by several rays, only the value of the closest one is represented.


img
A set of equirectangular panoramic images was taken with a 360° color camera in 1920x960 resolution. They follow the same trajectory.</dc:description>
