| 17:00 | se6ast1an | meeting time!
|
| 17:00 | se6ast1an | who is here?
|
| 17:00 | Bertl | is here ...
| | 17:00 | BAndiT1983 | am here
|
| 17:00 | se6ast1an | great
|
| 17:02 | se6ast1an | seems its a small circle today
|
| 17:02 | se6ast1an | BAndiT1983: any news to report?
|
| 17:04 | BAndiT1983 | sorry, not much, was investigating the firmware performance and preparing for gsoc2020
|
| 17:04 | BAndiT1983 | but in the last days other things came in-between
|
| 17:05 | BAndiT1983 | waiting for submissions from students, before doing bigger steps in the firmware/bootloader
|
| 17:05 | BAndiT1983 | that's it from me
|
| 17:05 | se6ast1an | right, thanks
|
| 17:05 | se6ast1an | Bertl: you have some things to share don't you?
|
| 17:06 | Bertl | well, mostly GSoC preparations as well here, but I managed to also whip up a bunch of PCBs for this purpose and make some progress on the ABCP PB
|
| 17:06 | Bertl | I've updated the Axiom Remote design to match the current state of the Prototypes we already have
|
| 17:07 | Bertl | and extend that with a remote control option
|
| 17:07 | Bertl | the remote for the remote :) is basically pads on the PCB to connect each and every button or rotary encoder
|
| 17:08 | pratyush | joined the channel |
| 17:08 | Bertl | which then, thanks to another PCB which can be attached at the bottom of the Remote, allows to remotely press the buttons and spin the dials
|
| 17:09 | Bertl | in addition to that it allows for side-channels to the PIC16s and programming of the PIC32
|
| 17:09 | Bertl | the design works together with a remote shield for the Axiom Beta, so it should be easy to create a remote controlled setup at the hub
|
| 17:11 | anuejn | is here
| | 17:11 | Bertl | on the USB3 front, my Test PC suddenly died, still not sure what is actually broken
|
| 17:11 | Bertl | but I replaced the motherboard and the graphics card and I'm working on getting the replacement up and running
|
| 17:12 | se6ast1an | do you still need my motherboard?
|
| 17:12 | Bertl | it wouldn't hurt to have a spare, yes
|
| 17:13 | Bertl | for the ABCP power board, the basic testing except for the switchers is done, and I'm able to program the new PIC16F15325 on the board
|
| 17:13 | Bertl | so the next step there is to write some power management and control interface to get the switchers tested
|
| 17:14 | Bertl | information gathered during the PB assembly was already incorporated into an updated PCB layout which is currently processed by OSHpark
|
| 17:15 | Bertl | those were only minor adjustments to improve the layout nothing which would change the functionality
|
| 17:15 | Bertl | I think that's it from my side for today
|
| 17:16 | se6ast1an | thanks, "write some power management and control interface to get the switchers tested" is a not too complicated task I assume?
|
| 17:17 | Bertl | not as complicated as writing the gateware for the Axiom camera :)
|
| 17:17 | se6ast1an | obviously
|
| 17:18 | se6ast1an | when do you think you can say if the switchers work or not?
|
| 17:18 | se6ast1an | and what can only be tested after the new PB arrives?
|
| 17:18 | Bertl | we should know this week I'd say
|
| 17:18 | se6ast1an | great
|
| 17:19 | Bertl | we cannot test the interaction between the existing elements on the PB and the new parts before the new PB arrives
|
| 17:19 | se6ast1an | right
|
| 17:19 | Bertl | but it should be possible to get an idea by using the current prototype together with an old power board
|
| 17:20 | se6ast1an | do you want to say a few words about the FFD measurement efforts that we want to focus again on now?
|
| 17:20 | Bertl | if you like me to, sure ...
|
| 17:20 | se6ast1an | please
|
| 17:21 | Bertl | well, it seems to be important for the ABCP to measure or at least compare the focal flange distance (FFD) on/between different cameras
|
| 17:22 | Bertl | a further goal is probably to also measure any angular mismatch between sensor and image plane
|
| 17:23 | Bertl | so we devised a bunch of methods to do those measurements and we plan to prepare a test setup and do some testing to figure out which one is best suited for our purpose
|
| 17:24 | Bertl | a very appealing and probably quite simple approach is to use the sensor feedback to do the measurements
|
| 17:25 | Bertl | e.g. have a setup with a grating or mask with holes which works like a pin-hole lens and two or more different colored light sources projecting through this mask/grating onto the sensor
|
| 17:26 | Bertl | then inspect the pattern on the sensor (ideally by simply reading out the sensor), do some math and get the proper distance as well as any angle between sensor and measurement setup
|
| 17:27 | Bertl | naturally this requires precise components to attach to the cameras e-mount as well as a way to measure the initial distance
|
| 17:27 | Bertl | (i.e. mostly works as calibrated instrument)
|
| 17:28 | Bertl | guess that's it?
|
| 17:28 | se6ast1an | perfect thanks
|
| 17:29 | se6ast1an | so further tests will be done plus some mechanical parts designed/manufactured
|
| 17:29 | pratyush | left the channel |
| 17:29 | se6ast1an | quick update from me
|
| 17:29 | se6ast1an | new screws that I ordered last week arrived
|
| 17:30 | se6ast1an | they solved the issue of the screwhead standing out of the enclosure
|
| 17:30 | se6ast1an | https://cloud.apertus.org/index.php/apps/gallery/s/CeTy5CZqBsLtBfm#
|
| 17:30 | se6ast1an | 3rd picture = new screws
|
| 17:30 | se6ast1an | torx everywhere
|
| 17:31 | se6ast1an | I also received dowel pins for the lens mount assembly, unfortunately installing them showed two missaligned holes, need to verify now if the drawings are incorrect or the manufacturing is to blame
|
| 17:32 | se6ast1an | Fabian Puttinger visited us today in the AXIOM office and brought his stereo 3D rig he built
|
| 17:32 | se6ast1an | https://realitydoesntneedme.tumblr.com/
|
| 17:32 | se6ast1an | https://cloud.apertus.org/index.php/apps/gallery/s/7JZd4Yd9pfszX3a#
|
| 17:32 | se6ast1an | he wants to collaborate to build a second generation from metal and for larger cameras, like the AXIOM :)
|
| 17:32 | se6ast1an | and open source/open hardware everything of course
|
| 17:33 | se6ast1an | I see he already joined the wiki and will draft name/plan for this project soon, then we can see who is interested in participating
|
| 17:34 | se6ast1an | its basically an adjustable orientation/distance beamsplitter rig for 2 cameras, so there might be many more interesting applications
|
| 17:34 | se6ast1an | beside stereo 3d
|
| 17:34 | se6ast1an | multispectral, HDR, etc.
|
| 17:35 | se6ast1an | thats it from my side
|
| 17:35 | se6ast1an | anyone else who wants to share some things?
|
| 17:35 | se6ast1an | vup, anuejn?
|
| 17:36 | anuejn | well, i dont have much to report
|
| 17:37 | se6ast1an | any news for the vienna hackathon plans?
|
| 17:37 | anuejn | currently we are still working on building axi stuff
|
| 17:37 | anuejn | but not much very visible progress
|
| 17:37 | anuejn | huh no, i guess
|
| 17:38 | anuejn | thats it from my side
|
| 17:38 | se6ast1an | thanks!
|
| 17:39 | se6ast1an | ok, anyone else?
|
| 17:39 | se6ast1an | otherwise we can conclude early today
|
| 17:40 | se6ast1an | right, meeting concluded then, thanks everyone!
|
| 17:40 | Bertl | you're welcome!

| 19:44 | pratyush | I have a new idea which I would like to work on. I intend to create a real-time face tagging system that could tag faces and that could be used in autofocus.I want also to create a filtering algorithm that could add special effects to pictures and some more AI-related features like background blur etc.
|
| 19:45 | Bertl | sounds interested ... where do you plan to implement that?
|
| 19:45 | Bertl | *interesting
|
| 19:49 | BAndiT1983 | changed nick to: BAndiT1983|away
|
| 19:51 | pratyush | I wolud like to implement it as a part of axiom Remote
|
| 19:51 | Bertl | you are aware that the Axiom Remote uses a PIC32 MCU?
|
| 19:53 | pratyush | yes
|
| 19:53 | pratyush | its an arm based mcu
|
| 19:53 | Bertl | so you plan to implement real-time face recognition and filtering on an MCU?
|
| 19:54 | Bertl | and the PIC32 is MIPS, not that this would matter
|
| 19:55 | pratyush | it check out the clock speed its only 80Mhz
|
| 19:55 | pratyush | i think thats not possible
|
| 19:55 | pratyush | to implement
|
| 19:57 | Bertl | it's actually a PIC32MZ, so the clock speed tops out at 250MHz
|
| 19:58 | Bertl | but I doubt that you will be very successful with 512KB memory :)
|
| 20:00 | pratyush | I do agree
|
| 20:02 | pratyush | But i checkout the website of tensorflow lite and the said that ESP32 like mcu could run tf-lite
|
| 20:02 | pratyush | which has similar specifications like PIC32MZ
|
| 20:06 | Bertl | well, I won't keep you from trying :)
|
| 20:07 | pratyush | :] I am still a student and a lot to learn
