Constructor & Destructor Documentation

SurveyPxbImage::SurveyPxbImage

(

)

SurveyPxbImage::SurveyPxbImage ( std::istringstream &  iss )

inline

Constructor from a string stream.
Observe the ordering: A line needs to be of the form rawID1 y_1_1 x_1_1 y_2_1 x_2_1 rawId2 y_1_2 x_1_2 y_2_2 x_2_2 sigma_y sigma_x
x_i_1 denoting the left, x_i_2 the right module. The data is then mapped to

-------------++--------------
        (1) +||+ (3)  
         ||
 left module || right module
         ||
         ||
        (0) +||+ (2)     
-------------++-------------- 

where (i) refers to the entry in the std::vector measurements
Therefore the mapping is as follows:

• y_1_1, x_1_1 -> (0)
• y_2_1, x_2_1 -> (1)
• y_1_2, x_1_2 -> (2)
• y_2_2, x_2_2 -> (3) The sigmas denote the Gaussian error of the measurement in the u and v coordinate
