CmpCalib

List of commands

Description

The CmpCalib command compares two files of calibrations (in general of the same camera).

Calibration parameters of a camera can not be directly compared, the command estimates a rotation to align the parameters. The output file Delta Calib.txt contains a function which gives the differences between the two sets of calibration as function of the radius and a grid which provides planimetric vector deviation between each rays directions.

Syntax

The basic syntax requires 2 args :

mm3d CmpCalib Calibration1 Calibration2 

• Calibration file corresponds to Ori-***/AutoCal_Foc-***.xml .

Help

A basic help can be asked with

 mm3d CmpCalib -help 

Mandatory unnamed args :

• string :: {First calibration file}
• string :: {Second calibration file}

Named args :

• [Name=Teta01] REAL
• [Name=Teta02] REAL
• [Name=Teta12] REAL
• [Name=L1] INT
• [Name=SzW] INT
• [Name=DynV] REAL
• [Name=Out] string :: {Result (Def=Name1_ecarts.txt)}
• [Name=DispW] bool :: {Display window}
• [Name=XmlG] string :: {Generate Xml}

Example

For example, in the Pierrerue Tutorial dataset, you can launch after the final adjustment :

mm3d CmpCalib Ori-Pierrerue/AutoCal*.xml Ori-MEP-Terrain/AutoCal*.xml  DispW=1
