17:00 | Bertl | MEETING TIME!
| 17:00 | anuejn | is here
|
17:00 | Bertl | se6astian will be late today, so please /msg me if you want to report
| |
17:01 | Bertl | okay, anuejn, please go ahead with your report
| |
17:02 | anuejn | after a survey of available rust TIFF / DNG libraries, I found that none of the librarys support zero-coppy reading / writing
| |
17:03 | anuejn | that would be an unnescessary performance bump
| |
17:03 | anuejn | so I decided to write yet another tiff library for rust
| |
17:04 | anuejn | Aditionally I understood the DCP format ("DNG Camera Profile")
| |
17:05 | anuejn | I can currently dump the IFDs of DNG files to Human readable YAML files
| |
17:05 | Bertl | that sounds great!
| |
17:05 | anuejn | currently I am building the YAML reading and DNG writing
| |
17:05 | anuejn | thats it from my side
| |
17:05 | Bertl | excellent!
| |
17:06 | Bertl | from my side, there isn't much to report. INT/LAM is still testing the changes we did including binning but there have been some unforseen delays on their side
| |
17:07 | Bertl | other than that, nothing relevant happened here ...
| |
17:07 | Bertl | any other reports?
| |
17:08 | se6astian | just arrived, brief updates from me:
| |
17:08 | se6astian | manual hdmi plugin module assembly planned for 21st
| |
17:08 | se6astian | the roadmap page has been updated with recent areas of developments
| |
17:08 | se6astian | https://www.apertus.org/axiom-beta-status
| |
17:09 | se6astian | please take a look and let me know if you find any error or typo
| |
17:09 | se6astian | thats it basically from my side
| |
17:09 | se6astian | many thanks Bertl for taking care of this meeting
| |
17:10 | Bertl | you're welcome!
| |
17:12 | Bertl | okay, so I guess that
| |
17:12 | Bertl | is it for today?
| |
17:12 | se6astian | yes :)
| |
17:13 | vup | I guess I can report some small news
| |
17:13 | Bertl | ah!
| |
17:13 | vup | I tried to capture some flatfields using the method suggested by ryan of just pointing the camera at a monitor
| |
17:14 | vup | however, my first try I left the camera inside the lense mount adapter / holder thingy
| |
17:14 | vup | which caused the edges of the sensor to not get as much light as the middle
| |
17:15 | vup | I now tried a second round, where I removed the lens adapter, which seems to work better, but its now hard to judge if the sensor is actually lit homogenously or what I get is just still non homogeneous illumination of the sensor
| |
17:15 | vup | nonetheless, i already did some basic analysis of the data
| |
17:16 | vup | and below the saturation the response curve seems to be pretty linear with deviations of at maximum about 1% from perfect linearity
| |
17:16 | vup | but when reaching the saturation value of the pixels the response curve starts to get pretty nonlinear
| |
17:17 | vup | furthermore there seems to be a wide spread of the actual saturation value of the pixels
| |
17:17 | vup | (about 98% of saturation values lie inside a interval of size ~450)
| |
17:18 | vup | the nonlinearity when reaching the saturation value is actually pretty helpful as it causes the slope of the response curve to get smaller, so one gets more dynamic range from that
| |
17:19 | vup | ill try to capture some more flatfields with the lens adapter remove soon and share some more in depth results then
| |
17:19 | vup | thats it from me
| |
17:20 | Bertl | thaks! sounds interesting!
| |
17:21 | Bertl | okay, last chance for any reports within the meeting then ;)
| |
17:23 | Bertl | thanks everyone!
| |
17:23 | Bertl | MEETING CONCLUDED!
