Re: Stereo camera with CM3 inside for OpenCV learners, drones and robotics

This is really cool project, I'll immediately order one when available. This is exactly what the foundation should have originally come up with, a compact CMIO board, usable as is for mobile (drones, etc) applications. I've been building a fixed-wing uav project for a while, utilizign a stereo-video...

Re: Stereoscopic camera capture - now implemented.

I can confirm that max_preview_height modification works for me as well, if I set --height to single channel height instead of total height (unlike -3d sbs which takes --width as total width i.e. doubled).

I still have problems with playback geometry but that's maybe another problem.

The mentioned max_preview_height modification to RaspiVid.c only fixes the live preview problem, am I right? I'm using --nopreview flag so this must be different issue.

Re: Making a custom 'motherboard'

How is the project going? I have similar needs for custom motherboard, because the original is too heavy for RC airplane use. I only need dual regular-size camera ports (3D FPV), usb host pads for wifi, gpios hardwired for dual camera use, uart, maybe i2c and few extra gpios, and of course simple po...

Re: Stereoscopic camera capture - now implemented.

I'm also having the "stalled pipeline" problem with top-bottom mode, i.e. nothing comes out from raspivid. The SBS mode works fine.

Re: HDMI settings for OSVR

The solution is to specify custom hdmi_timings with values taken from the EDID output. The following lines in /boot/config.txt enables the 1080x1920 mode for OSVR HDK 1.4: [EDID=SVR-OSVR_HDK] hdmi_ignore_edid=0xa5000080 hdmi_group=2 hdmi_mode=87 hdmi_timings=1080 0 32 5 11 1920 0 12 5 6 0 0 0 60 0 1...

HDMI settings for OSVR

I'm trying to get HDMI output from Raspberry Pi 2 to be displayed on OSVR HDK 1.4 virtual reality viewer. It features single 1920x1080 LCD and single channel HDMI interface, nothing special. I don't care about motion tracking etc. stuff, I just want to see the image. For some reason the image is tot...

Thanks for clarification. I was too optimistic. Since chip pads inaccessible, diy camera support seems to be totally out of question.

Re: Big price drop on camera modules at RS - £7.99

Pi Zero doesn't have the camera slot... so only usb cams for that. Techically the Zero is as capable of driving the camera as the "big sisters". It just doesn't have the correct pins exposed to CSI connector. I wonder if anyone (the foundation?) comes up with software hack which re-maps the correct...

Adding camera to Zero using GPIO pins

Is it technically possible to re-map CSI pins to GPIO pins (in software), so that the standard RPi camera module could be connected to Zero board? Adafruit uses similar technique with their Kippah display. PS. I wish the Foundation released Zero+ with CSI connector. Odroid managed to do that with th...
