Re: Which chessboard for the calibration phase

Oops, I did not see this file. This time I managed to capture pairs in which the script found the chessboard in half of them. Unluckily the image was highly distorted (looked like a big barrel distortion, although I used the not-fisheye script of the tutorial) and highly cropped. A second capture of...

Re: Basic stereophoto with raspistill

Erratum: I just noticed today that decimate option in conjunction with height/width specification is a bad idea as the full view if not used and moreover the aspect ratio is odd. Just remove the -dec option and it would be OK.
I will edit the original post to reflect this observation.

the first ten accepted entries
Are they the first received and accepted entries, or do you gather all submits and rank the 10 best at the end of month?
A collateral question would be... should we hurry to submit or should we take the time go craft a nice report?

Which chessboard for the calibration phase

I try to replicate OpenCV tutorial https://medium.com/stereopi/opencv-and-depth-map-on-stereopi-tutorial-62cb6792bbed In the 4th step, the script says "No chessboard could be found." for each image. I tried several chess patterns with few big cases and more small ones, but it changed nothing. I also...

SSH & VK on OpenCV image

I just flashed the OpenCV image and I am quite disappointed: there is no ssh server thus I cannot connect to it.
I found a mouse and tried to interact with it, but there is no virtual keyboard neither, thus I have to find a USB keyboard too now.

Re: Oculus Go livestream?

Realizor said in another thread that the project is paused because of lack of developer. Is there a place to see your specifications ? Actually, I know a guy that was freelance last time I met him and who basically made some projects similar to this (with cameras, occulus and mobile). His situation ...

Re: 360 video

According to https://www.crowdsupply.com/virt2real/stereopi#demo-360-panoramic-photos-and-videos someone started to test 360x180, at least in photo. I suspect fisheye stitching being a bit heavier than rectilinear camera images, so you possibly would get a lower FPS at same size, but in theory it so...

Capcha registration

There are robots that post ads on the forum. Captcha do not work, because pawning a captcha is cheap (some people are paid around 1$/1000 to solve them instead of robots) In the past, I saw that adding a simple checkbox "I am not a robot" (not a captcha, a simple checkbox without external service ca...

Re: Sources of com.virt2real.stereopi

I understand the dilemma. Personally, I do not like to release too early, especially in the phases where it does not work or where it changes architecture a lot. However, I try to share in pretty early stages nonetheless (often around the first basically usable version). The rational is based on mul...

Re: Hardware power and transfering data

There is no builtin wifi, but you can add a dongle. Also, most phones nowadays include a simple wifi hotspot that can be useful with stereopi. Network can also be used via Ethernet, but it still requires infrastructure. The third way highlighted by Realizator is to use USB gadget which makes the ste...

Re: sync external flash (light)

I think triggering a commercial flash is done by shorting two pins of its connector (keyword: hotshoe). However, because it is high voltage (compared to stereopi) you will need to add some electronics between the stereopi and the flash, probably only an optocoupler and resistors. I let you make your...

Are the sources of com.virt2real.stereopi Android app publicly available somewhere? I would like to make a similar app, but which: 1) displays in 3D on my autostereoscopic screen 2) has a record button to take photographs (and maybe control of some other params in the future) I will probably do it f...

Re: Camera multiplexor crazy idea

Woow, it looks mega expansive for the task; but I might have not understood the whole thing. If you can switch between two kind of cameras, you can profit from them. However, I suspect you will have to stop and start for the switch to work (and perhaps reboot, depending on how initialization is done...

Good job, except that the videos are not in 3D. :D
The written documentation is more complete and already say that, but as people tend to not read it is a good complement.

Maybe you can add these files to the "DIY Ninjas Section" of the wiki.

I practice stereophotography for a few years now, and window violation is a very common mistake for beginners.
