22:33 | Bertl | troy_s_, rexbron: so, any clues from the IT8 chart yet?
| |
23:35 | rexbron | Bertl: sorry, haven't had the chance to look at it
| |
23:35 | rexbron | I've got a music video I'm pulling focus on tomorrow. First time I've ever worked with IR
| |
23:36 | Bertl | no problem, I was just curious
| |
03:56 | Bertl | off to bed now ... have a good one everyone!
| |
04:45 | troy_s_ | Bertl: I am on location in Florida so I can't do any computer work thanks to the lack of a computer.

11:53 | Bertl | welcome intracube!
| |
11:54 | intracube | hi Bertl :)
| |
11:54 | intracube | what's new in the land of Apertus?
| |
11:54 | Bertl | depends, what is your status? :)
| |
11:55 | intracube | I haven't been following things for a few months.
| |
11:55 | Bertl | then there are many new things, I guess ...
| |
11:55 | intracube | any news on the camera hardware and development?
| |
11:56 | Bertl | https://www.apertus.org/alpha_prototype
| |
11:57 | intracube | why aren't the posts on that page listed newest at the top!
| |
11:58 | intracube | I saw that page and thought nothing had been added since Feb
| |
11:58 | Bertl | yeah, well ...
| |
11:58 | intracube | :)
| |
12:01 | Sasha_C | joined the channel | |
12:04 | intracube | cool, so a lot has been happening
| |
12:04 | Bertl | yup
| |
12:04 | intracube | are there any more samples other than this: https://www.apertus.org/sites/default/files/colors_500ms_composed_0.jpg
| |
12:04 | intracube | ?
| |
12:04 | Bertl | http://vserver.13thfloor.at/Stuff/AXIOM/RAW/
| |
12:05 | intracube | awesome, thanks :)
| |
12:05 | Bertl | but note: it's a known broken sensor and we have no proper setup yet
| |
12:05 | intracube | do you know the cause of the faint cross-hatching?
| |
12:06 | Bertl | i.e. prototype cannot be user like a camera ATM, but be are getting there
| |
12:06 | Bertl | you mean the horizontal and vertical stripes?
| |
12:06 | intracube | yep. most visible in the coloured stripes
| |
12:06 | intracube | de-bayering?
| |
12:07 | Bertl | no, I think it is missing calibration of columns and rows
| |
12:08 | intracube | ah ok
| |
12:09 | Bertl | but maybe it is something else, we don't really know yet
| |
12:09 | Bertl | latest image is the IT8 one
| |
12:09 | intracube | I'm really impressed by the sharpness
| |
12:09 | Bertl | and we are not even able to focus properly yet
| |
12:09 | intracube | I'm thinking about getting a Nikon D610. it looks a great DSLR but the video is obviously poor by comparison to the axiom
| |
12:10 | Bertl | it takes about 15 seconds to transfer the image via ethernet
| |
12:10 | Bertl | so imagine getting the focus right with 15second delays between each image :)
| |
12:19 | Sasha_C | Might a video out feed to monitor / viewfinder screen at lower resolutions be possible, for previewing and focusing?
| |
12:20 | Bertl | we are working on HDMI out, so yes, that will happen :)
| |
12:20 | Sasha_C | So the 15 second delay comes into effect when recording a raw image at 4K res, over ethernet?
| |
12:21 | Bertl | yes, the transfer from memory and over thernet atm
| |
12:21 | Bertl | recording the image to memory only takes a fraction of a second
| |
12:22 | Bertl | i.e. we could record a few images (4-5) at probably 40FPS at full resolution (4096x3072)
| |
12:23 | Sasha_C | you mean the sensor could capture 40FPS, but out of all those frames, only 4-5 could be captured with the current setup?
| |
12:24 | Bertl | yes, the sensor can do much more than 40FPS, but the interface to the FPGA currently limits us to half of the possible performance, and the memory on the ZedBoard limits us to a few frames
| |
12:24 | intracube | is it still the case that the prototype will read off a windowed 16:9 area of the sensor?
| |
12:25 | Bertl | maybe, we'll se what we do once we get there
| |
12:25 | Bertl | we will definitely have to use the HDMI out for sequences
| |
12:26 | Bertl | which limits us to 1080p or so
| |
12:26 | Sasha_C | Bertl, does this mean that the zedboard won't be viable for high-speed capture on the final AXIOM?
| |
12:26 | intracube | I know this is probably hard to answer right now, but should the final hardware be able to read off the entire sensor (4:3)?
| |
12:26 | Bertl | Sasha_C: the zedboard won't be near the final AXIOM :)
| |
12:26 | intracube | even if it's not full (4K) resolution
| |
12:27 | Bertl | the AXIOM (not alpha prototype) will do 4K raw at 150 FPS or so
| |
12:28 | Bertl | (given that you have sufficient illumination that is)
| |
12:28 | Sasha_C | Yeah, that's what I thought. But what hardware will replace the zedboard?
| |
12:28 | Bertl | once the alpha prototype is finished and the crowdfunding successful, we will start building our own AXIOM prototype (custom hardware replacing the zedboard)
| |
12:29 | Sasha_C | I.C
| |
12:29 | Sasha_C | i guess that wasn't made too clear. I thought there was the possibility to reuse the zedboard in the final AXIOM unit
| |
12:30 | Bertl | nah, the zedboard has a number of disadvantages for AXIOM
| |
12:30 | Bertl | but it is a good starting point for the alpha prototype
| |
12:30 | Bertl | (otherwise we wouldn't be where we are now :)
| |
12:31 | Sasha_C | yeah, so true :)
| |
12:32 | Sasha_C | Hey, off topic... This chat room is going to get pretty damn crowded tomorrow night (or afternoon, depending on your location)?
| |
12:33 | Bertl | yes, afternoon here
| |
12:35 | Sasha_C | I only hope there's a reasonable level of civility and that everyone displays some kind of civility
| |
12:35 | Sasha_C | oops, that doesn't make sense (I'm getting tired
| |
12:36 | Sasha_C | I meant to say, I hope that with many people on here, everyone takes the time to listen to what others have to say without hijacking the meeting's agenda
| |
12:38 | Bertl | well, we'll see, if it gets too crowded/confusing, we can always switch to voice/invitation
| |
12:39 | Bertl | (voice means a moderated channel)
| |
12:39 | Sasha_C | right
| |
12:42 | Sasha_C | What are your thoughts regarding the hardware that will have to be built to replace the zedboard in the final AXIOM? Can you describe the specs that will be required for, say, shooting 4k raw at 100FPS?
| |
12:43 | Bertl | well, we will need something with gigabit tranceivers for that to work, like the zynq-7030 for example
| |
12:43 | Bertl | and we probably want to have some ram available to the FPGA fabric for buffering
| |
12:46 | Sasha_C | Is the estimated crowd-funding target still at around 150,000 euros?
| |
12:48 | Bertl | we haven't done a serious calculation yet, we'll do that when we have some clues when the prototype is finished
| |
12:48 | Sasha_C | ok, thanks for the update
| |
12:49 | Bertl | np
| |
13:20 | intracube | indeed, thanks for the info Bertl
