BINGO 5.02 - December 2003
This page describes BINGO as it existed at the stated release date. For current behavior and requirements, use the current Manual, Reference, and Guides.
Several minor corrections and enhancements have been done.
Program BINGO
A problem with photo sequence optimization in blocks with more than 2100 photos has been solved.
In the GPS/IMU data files, single GPS or IMU observations can be set inactive by using a negative value for their standard deviations. This can be applied separately for the position, for phi/omega or for kappa, and as well as for any combination.
In case of GPS/IMU data for all photos, the initial photos orientations do not need to be defined necessarily by program RELAX anymore. BINGO can use the GPS/IMU data to establish the initial data directly. However, for elimination of gross errors in the photo measurements it might be useful to apply RELAX first.
The adjusted photo coordinates and their residuals can be written optionally to a separate file with name "imresi.dat" (fixed name). The new key for this option is found in the GUI on page "Listing" in the lower left corner. The default for this value is "do not write".
A new statement "PPSP" allows entering the position of the principal point of symmetry (PPS) for BINGO processing. Normally it is assumed, that all photo coordinates have their origin in PPS. But in case that this is not possible by any reason, this statement can be used to define the position of PPS. Two different applications are possible: the definition of PPS by given values, or the estimation of PPS in the same location as PPA, the principal point of auto collimation, which is the perspective center in the image plane. The format free syntax is:
PPSP camera_name x_PPS y_PPS
or PPSP camera_name =PPA
If PPS shall have the same position as PPA, the string "=PPA" has to be typed. All additional parameters are referring to this position of PPS, as well as any given radial symmetric lens distortion (RADI statement).
Stereo metric camera conditions (SMCO) are now allowed as well for aerial photos. However, the base components and their precision values have to be defined in advance by means of ECES / ECCA statements. The stability of the base has to be defined by a SMES statement. The short form defining all components in the SMCO statement is not allowed for aerial photos.
Program BBMAN (BINGO Manager)
In the BINGO manager's window the menu for the tools has been reorganised in groups.
Program IMPLO
A new plotting program "IMPLO" has bee added to the tools to show systematic effects of remaining photo coordinate residuals and their significance. Output is done on the selected graphical device as well as on list file with name "implo.lis". This program will help to select additional parameters. Creation of file "imresi.dat" is required (see above).
Program REPLO
Program REPLO allows now to draw true foot prints. The foot print size will be estimated using the corner points of each photo. The photo coordinate file is required to find these points. If this file is not available, a median height will be used to estimate the corner points. There is no warning, if this file is not found. The foot prints can be drawn in their full size or in a reduced size. This reduced size (1/3) might provide a better overview.
Program REPLO allows drawing lines, given in a file with default file name "lines.dat". If the option for the lines drawing is set, the file should exist. Each line in the file represents one point of a polygon. A line ends, if an empty line is found. Each point has the format:
Point-id [ X Y [ Z ] ]
I.e. a point-id has to be given. Z is optionally, as well as X and Y. If no coordinates are given for a point, the coordinates for this point-id will be searched first in the list of adjusted points, and then in the list of photo-ids. If the point is not found, the line will be interrupted.
The option to draw vectors for residuals of control points, GPS data or check points in program REPLO has been divided in options for X/Y and for Z to see the effects separately.
Program RELAX
The parameter CLIP for photo number differences has been changed. In the prior version a relative orientation between photo numbers from different strips e.g. 4_034 and 5_035 or A7C056 and B7C057 had been performed regardless a parameter CLIP=1, because only the ending digits e.g. 034 and 035 have been checked. The new version estimates the lexical distance between the photo names and avoids in both cases a relative orientation, if CLIP=1 is set.
