Cameras R200

Hello good afternoon.

I want to ask about an error I have when I want to take a picture with the R200

I write the following command

sudo gst-launch-1.0 v4l2src device = / dev / video0 num-buffers = 1! jpegenc! filesink location = "rs.jpg"

and I get that error!!

This is my kernel version

Kernel version

Linux intel-aero 4.4.76-aero-1.2 # 1 SMP PREEMPT Thu Dec 21 09:55:38 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

My number of video devices

but I also have this error

and it says that I do not have any camera connected, but I have my R200 connected to the intel aero

How can I solve these problems that the R200 camera gives me?

Hi MarioTavarez,

 

 

Thank you for your interest in the Intel Aero drone.

 

What if you connect to the drone's wifi access point? Do you get the same error?

 

https://github.com/intel-aero/meta-intel-aero/wiki/08-Aero-Network-and-System-Administration

 

Also, try rebooting after connecting to the Aero access point.

 

Let me know if it works.

 

 

Regards,

 

Alexandra

You are kidding, right? the answer that you just gave me sincerely has nothing to do with the problem

Hi MarioTavarez,

 

 

I tested this issue while the drone was connected to a wifi network and I got the same error as you.

 

After connecting to the drone's acces point and rebooting, it worked.

 

This is why I suggested this. Let me know if this fixes your issue so I can investigate further in case it doesn't.

 

 

Regards,

Hello,

I have the same problem. Exactly the same error messages as MarioTavarez has.

Kernel:Linux intel-aero 4.4.76-aero-1.2 # 1 SMP PREEMPT Thu Nov 9 21:20:17 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Connecting to the drone's wifi network didn't solve the issue.

I also tried to use the Realsense D435 on the drone. Here https://github.com/intel-aero/meta-intel-aero/wiki/90-(References)-OS-user-Installation https://github.com/intel-aero/meta-intel-aero/wiki/90-(References)-OS-user-Installation you say that the R200 and the D435 need different kernel drivers. May it be possible that after installing the drivers for D435, the R200 is not working anymore?

BIOS_VERSION = Aero-01.00.16

OS_VERSION = Ubuntu 16.04.4 LTS"

AIRMAP_VERSION = unknown

FPGA_VERSION = 0xc2

AeroFC firmware version = 1.6.5

With BIOS_VERSION Aero-01.00.13 I had the same problem.

MarioTavarez,

 

 

You should try reinstalling the camera drivers and make sure you are using USB 3.0.

 

https://github.com/intel-aero/meta-intel-aero/wiki/90-(References)-OS-user-Installation# number-of-video-devices

 

 

MaEp,

 

 

The branch choice depends on the camera you are using.

 

If you are using the Aero camera, you should use the R200 branch, but if you are using a third party camera, you should use the main branch of the SDK.

Do you know how I can access the camera below? How can I take a picture from that camera? is that it only appears from video 0 - video13

but how do I access the camera below. With Opencv I need to access that camera since the camera needs to detect an object that is below it.

I have the vision accesory kit

I want to access the third camera that is to the camera that you see down, I want to take photography and video from that camera called bottom, do you know how? for what I see does not come as access to that camera directly

 

for what I see does not come as access to that camera directly

Hello MarioTavarez,

 

 

In the link below you have instructions on how to access each camera:

 

https://github.com/intel-aero/meta-intel-aero/wiki/06-Cameras-and-Video

 

 

You can access the bottom facing camera with /dev/video2

 

 

Regards,

I returned the following error with video2

I want to take a photo with /dev/video2.

By the way, I also wanted to ask about a USB camera,

is it possible to connect a USB camera to the Intel Aero? and if so, how could I access it?

Hi MarioTavarez,

As stated in the guide I suggested in my previous message, you can access the camera with /dev/video2 but can't stream this device with gstreamer. Instead, you can download a sample code from https://github.com/intel-aero/sample-apps/tree/master/capturev4l2 https://github.com/intel-aero/sample-apps/tree/master/capturev4l2 to see how you can capture a few frames to raw format, then output jpg frames:

git clone https://github.com/intel-aero/sample-apps.git

 

cd sample-apps/capturev4l2/

 

make

 

C=10 INPUT=1 MODE=PREVIEW ./capture_v4l2 --userp -d /dev/video2

 

ffmpeg -f rawvideo -s 640x480 -pix_fmt yuv420p -i Image-video<*> test.jpg

 

 

Regarding your second question, what are you trying to accomplish by adding another camera? What camera model?

 

 

Regards,

 

Alexandra
