All the files listed here are the one used by the "QuickStart" sample.

 

.prjt file

 

During texturation, RhinoCityTM use a ".prjt" file to define cameras and images to be used.

 

 

Camera Number is the number of cameras used. Here, 5 is the number :

Camera_Number: 5

 

For each camera, there is a Camera_File entry giving the path to the camera file definition. Here : 5 entries

Camera_File: C:\RhinoCity\Samples\QuickStart\Config\camera145.cam

Camera_File: C:\RhinoCity\Samples\QuickStart\Config\camera147.cam

Camera_File: C:\RhinoCity\Samples\QuickStart\Config\camera148.cam

Camera_File: C:\RhinoCity\Samples\QuickStart\Config\camera159.cam

Camera_File: C:\RhinoCity\Samples\QuickStart\Config\camera163.cam

 

Translation let's you to give a possibly translation apllied to you 3D model. Here, there is no translation given :

Translation: 0.0 0.0 0.0

 

Extern_Orientations is used to give the path to the '.flt' file. Here :

Extern_Orientations: C:\RhinoCity\Samples\QuickStart\Config\RhinoCity.flt

 

Intern_Orientations must always be None :

Intern_Orientations: None

 

Images_Folder is the folder path where images are stored. Here :

C:\RhinoCity\Samples\QuickStart\Images

 

Texture_Folder is the folder path where texture atlas will be created. Here :

C:\RhinoCity\Samples\QuickStart\Textures

 

Images_Ext is the extension of image files. Here :

Images_Ext: tif

 

Textures_Ext is the extension of texture atlas that will be created. Here :

Textures_Ext: jpg

 

Temporary_Folder is the folder path used internally during process to save temporary files. Here :

Tempory_Folder:C:\RhinoCity\Samples\QuickStart\Temp

 

Pack_Folder : if present, must be equal to Texture_Folder (keeped for compability with older version). Here :

Pack_Folder: C:\RhinoCity\Samples\QuickStart\Textures

 

 

 

.cam file

 

The camera '.cam' file contains parameters related to a camera.

 

 

 

Type is always Numerique

Type: Numerique

 

Name is the internal name of the camera. These name is used in the .flt file, here :

Name: 145

 

Focal is the sensor focal in millimeters. Here :

Focal: 82.0426

 

Photo_PrincipalPtOffset is the offset of the sensor center in millimeters. Here :

Photo_PrincipalPtOffset: 0.035 -0.1198

 

Photo_FiducialCoordinate is the number of fiducial coordinates given to describe the camera. Here the number is 4.

Photo_FiducialCoordinate: 4

 

Next, are the coordinates given in millimeters. Points are to be described counterclockwise

Here :

24.528 18.396

-24.528 18.396

-24.528 -18.396

24.528 -18.396

 

Those values are related to the sensor size. Here, the sensor width and height are :

Width : 2x24.528 = 49.056 mm

Height : 2x18.396 = 36.792 mm

 

Respecting the counterclockwise direction, the most important is to start by the correct first point : the choice of the first point determines the rotation of the sensor.

Here, we have started by the "Top/Right" point :

Point #0 (top/right) : 24.528 18.396

Point #1 (top/left) : -24.528 18.396

Point #2 (bottom/left) : -24.528 -18.396

Point #3 (bottom/right) : 24.528 -18.396

 

 

Radial_Distortion is a way to describe a possibly radial distortion. Here, there is no distortion :

Radial_Distortion: 0

 

 

Pixel_Width is the with of the camera in pixels. Width is here 8176 pixels :

Pixel_Width: 8176

 

Pixel_Height is the height of the camera in pixels. Height is here 6132 pixels :

Pixel_Height: 6132

 

 

 

.flt file

 

The '.flt' file contains informations related to images.

 

 

The first three lines of the file give informations needed to read well all other lines regarding the angles.

 

AngleUnit is the unit used to describe angle values. This entry can be "Degrees", "Radians" or "Grades". Here, angles are expressed in degrees :

AngleUnit: Degrees

 

AngleDir is the direction of angles. Possible values are "Trigo" or "InverseTrigo". Here, direction is "Trigo" wich is the same than "couterclockwise" :

AngleDir: Trigo

 

AngleOrder is the way to give the columns order of the next lines describing images. Values must be "Omega", "Phi" and "Kappa" in a certain order. Here :

AngleOrder: Omega Phi Kappa

 

All other lines describe images. Those lines are organized in columns like this one :

001_001_145000018 595029.801 5797105.239 1332.435 -0.03335 45.18026 -90.09151 0 145

 

Column #1, the image name, without extension : 001_001_145000018

Column #2, X coordinate : 595029.801

Column #3, Y coordinate : 5797105.239

Column #4, Z coordinate : 1332.435

Column #5, Omega (according order given by AngleOrder) : -0.03335

Column #6, Phi (according order given by AngleOrder) : 45.18026

Column #7, Kappa (according order given by AngleOrder) : -90.09151

Column #8 is always 0

Column #9 is the camera's name as given in the '.cam' file : 145
