Re: Set max resolution

Pascalfaust, I put some photos of my current idea in this tweet. Will test the new revision of this HQ housing in a few days :-)

Re: Set max resolution

A few days ago I did a solution for the calibration of the FullHD images (3840x1088) with a couple of new HQ cameras. I used video mode capture and did a 3x scaling down of captured images for the preview window. I used 10 fps, it works fine, but a recording of the image takes some time. The average...

Re: USB Wifi stops after Stereopi is accessed from Android

Ah, raspi-config try to save updated config files, but our filesystem is read-only. Try to unlock both "/" and "/boot" before the raspi-config: sudo mount -o rw,remount / sudo mount -o rw,remount /boot As for logs - all of them are disabled, as we have a consumer-like approach and read-only filesyst...

Re: apt-get update SLP image trouble

Zoldaten, apt-get upgrade is a bad thing, as I mentioned :-) At least you can see the error stage - "Starting local network connection on Wlan0". Try to look in run.sh and find the workflow we use. Some tips: In run.sh we are starting wlan manager: ./scripts/wlan-switch.php & this file includes "wla...

Re: apt-get update SLP image trouble

Zoldaten, I just planned to suggest you unlock BOOT, but you find this by yourself! :-) As for the reboot - as you mentioned, run.sh is the main file we start to run. So you can simplify it (by commenting) and find the reason for your reboots. All reboots we used have some special reason (like imple...

Re: USB Wifi stops after Stereopi is accessed from Android

I'm glad it works for you! :-)
As for the UART - we have "enable_uart=1" in /boot/config.txt by default. But we reconfigured UART as a serial com-port for the telemetry data flow. But you can assign UART back to Console using "raspi-config".

Re: USB Wifi stops after Stereopi is accessed from Android

Hi Samir_sogay, Power lines to USB ports goes directly from the power source. We did it specially for cases like yours, when you need to connect high-power USB device. Your Alfa is really hungry for power. Just use more powerful power source, and it should work. Actually, when you start a livestream...

Hi Zoldaten, This partition feature has been discussed on our forum :-) To say briefly, after each boot SLP try to fond FAT32 partition, and if it is not existing - try to create it, using all free space... after it's 2Gb of ext4, i.e. 3932160 in our case. And does a reboot after that. So if you ext...

The USB ports offen lack power, sometimes limiting to 2 amps. The stereopi, however, might ask for mor than that
Actually, USB 2.0 is limited by 0.5A (500 mA). But I agree, to catch up that problem we need at least to exclude the power issue.

Hi Fraserbaton, Yep, the plywood drilling without splitting on the opposite side is a tricky thing. You can google for the details. ABS plastic is an expensive thing for DIY details. We are considering to use acrylic plastic (like for the camera mounting plates in our kits), but it also has some spe...

Re: how to stream to stereo-pi apk ?

Hi Zoldaten, Actually mentioned pyimagesearch livestream solution is not so good. Try this way to get insights :-) It is for another purposes, not for the real-time low-latency. As for the scripts: 1. Take a look at the /opt/StereoPi/scripts/video-source.sh The last row activates the livestream. Her...

Re: Set max resolution

Hi Jlurban! You see, the full-resolution video capture is extremely consuming task. You should try either use a photo capture for the full resolution, or, for example, set a very small FPS. Can you please share a piece of code you use for the camera settings? Pascalfaust asked a good question. What ...

Re: how to stream to stereo-pi apk ?

Hi Zoldaten, To say briefly - it is really difficult. OpenCV is not so good at live stream. And also our application is focused on RAW H264, not friendly for OpenCV. You can use one special approach. Like capture a video, "split" it into two streams, and use one stream for the live stream, and anoth...

Re: Unreadeable recorded video in SLP

May be on-the-go conversion from raw H264 to the readable MP4 is an issue. But raw264 is very uncomfortable for the viewing (no scroll, etc). We need to investigate this issue.

Re: Another Stereoscopic Camera Project

If the stereopi was streaming video all the time, I can imagine this would take up the mobile data quite quickly, but do you think it would be possible to turn streaming on and off with a button press, like taking a photo...
