3D image

Is it possible to enable 2 camera to have 3D image?

The compute module version of the raspberry has 2 camera interfaces allowing 2 pi cameras to be attached but only 1 is active and processed by the GPU at a time.

This software supports the compute module and allows switching between the 2 cameras using the cn command which can be sent into the command PIPE.

If you are just interested in getting 2 still images from the cameras for processing into a stereo view then this would be possible by issuing an im command followed by a cn command (to switch cameras) followed by another im command.

If you want true simultaneous image capture or simultaneous video capture then you really need 2 Pis. The software runs well on a Pi Zero so that is an option. You then need to send in commands to both Pis close together.

349/5000 I am using StereoPi https://www.crowdsupply.com/virt2real/stereopi It already comes with a module but I would like to use RPI_Cam_WEB because it has more controls in the photo. But RPi_Cam_web only triggers a camera would like to trigger both. From the Raspistill command line this is possible by entering the 3d example .: raspistill -3d sbs -w 1280 -h 480 -o 1.jpg De: roberttidey <[email protected]> Enviada em: segunda-feira, 29 de julho de 2019 04:50 Para: roberttidey/userland <[email protected]> Cc: 2print <[email protected]>; Author <[email protected]> Assunto: Re: [roberttidey/userland] 3D image (#12) The compute module version of the raspberry has 2 camera interfaces allowing 2 pi cameras to be attached but only 1 is active and processed by the GPU at a time.

OK. This is using the -3d option supported by raspivid to run both cameras through the GPU simultaneously.

Currently tthe RPi Cam software doesn't support that.

In principle, it can be achieved by adding a bit more support in the MMAl layer, so I will investigate it further.

If I add support for it in then I won't have the means to test it as I don't have compute module / stereo camera set up. So it would just be supplied for external testing.

if you send me I test here De: roberttidey <[email protected]> Enviada em: segunda-feira, 29 de julho de 2019 14:39 Para: roberttidey/userland <[email protected]> Cc: 2print <[email protected]>; Author <[email protected]> Assunto: Re: [roberttidey/userland] 3D image (#12) OK.
