Hi!
I have just finished compositing this large Venus panorama from Mariner 10. I have tried to generate natural colors for the planet using orange and UV filters. Raw frames: FDS 58870-59038 I used 78 frames in that range and then picked out a few other frames to fill in the gaps. There where about 5% missing data. I did dark subtraction and flatfielding. for flatfields i used the venus images that looked flat enough. Does anyone have any information on camera linearity and stuff? I cant seem to find the calibration report; "MVM 73 TV Subsystem Calibration Report". if anyone has it, please let me have a look! The full panorama is 4000*4000 pixels. All processing is done in either floats or 16bit. Take a look! /mattias Venus realistic colors Venus enhanced colors Venus in UV |

I wrote a simple 3dsmax script that converted the mariner raw tape dumps into "png" files. It also created a corresponding text file with the image label info.
Then i wrote a second script that went trough all files and renamed them to YearDayGmtFDS.png so that i could sort out the FDS resets and move the files into Folders one for each FDS reset. Then i finally renamed the files to FDS.png. (and put all duplicate images in a special folder.) I also made a log file for each folder that contains all lable data for each image. FDS, Year, Day, GMT, Camera, Filter and Exposure. So now I have a mariner dataset in cronological order. (makes everything way easier to handle). Its easy to find each mosaic, I just look in the log file or use photoshops File Browser to find what I need. I will contact Mark about the calibration report. (thanks for the pointer) Btw, I have made a bunch of other large panoramas aswell. I need to make some kind of hompage at some point to showcase them all... for now its just a folder on the internet... take a look at : A folder with most of my composites |
