beaglebone blue camera

It should cool off those warm processors when maxing out your metal, PCB, and silicon. molloyd@beaglebone:~/exploringBB/chp12/openCV$ cd / So, I am wondering if you have commands that streams video to the BBs internal port, and then OpenCV commands that can access that from an external computer? Face at: (506,292). to the PKG environment variable. In this video I look at how you can get started with video capture and image processing on the Beaglebone. all display all information available Hi Derek. -name "opencv.pc" Specifically, that first example there right towards the top of the page, under the Fix webcam 1 section. I checked my BeagleBone image and it is working from the pkgconfig default directories. Play audio data using HDMI audio and USB audio adapters. Stream audio data to the internet using UDP. Camera PTZ kit assembling instruction part 1, Attaching the camera PTZ kit to the the robot chassis, Connect the USB camera to your Beaglebone USB port, Connecting servos 1 and 2 (horizontal and vertical respectively), And that's it. The reason I ask is because the grave character ` that wraps pkg-config always seems to cause problems. Any help will appreciated When build the face detection program got this error, root@beaglebone:~/exploringBB/chp12/openCV# ./face molloyd@beaglebone:/$ sudo find . Thanks. Find them at our lessons page. Regarding the last post Both of the lower-cost cameras work well for image capture, computer vision, and audio capture applications. **************************************** I just tried the build script under a clean image of Linux beaglebone 3.8.13-bone70 and it appears to work correctly: upper_blue = np.array([130,255,255]) # Play with these values too! Derek. unable to locate package v41-utils. Once you turn on your robot and connect it to the. http://www.linuxquestions.org/questions/linux-general-1/udev-webcam-rule-read-but-not-working-4175427378/ That means that you have to do the installation manually. This may mean the package is missing, has been obsoleted, or is only available from another source. P.S. But the point here is that if your numbers are different, then by all means plug your specific values into the sample rule I posted above. Im running the latest Bone image and trying to replicate building of boneCV.cpp (12-3) on my bone.

Anyway, I am unsure where to go from here, but cant see how you got that line to work (the v4l2-ctl set-fmt line), given the error I showed above. Enjoy! Derek: I left my bone on my desk at my office, so Ill check first thing tomorrow morning. For instance when I try, I get this export QWS_MOUSE_PROTO=LinuxInput:/dev/input/event1 for adding Touch screen to my QT APP, Check steps to assemble the Camera PTZ kit. The site structures and contains all of the digital media that is described in the book. Fully open source and actively supported by a strong community, the real-time performance, flexible networking, and rich set of robotics-oriented capabilities make building mobile robots with the Blue fast, streamlined, affordable, and fun. Worked like a charm. Common options: VIDIOC_QUERYMENU: Invalid argument So I need to go recompile the capture.c file to length the select() timeout, which is easy enough. I guess that you may have worked it out by now, but it is v4l (letter l), not v41. No problem. -d, device= use device instead of /dev/video0 The chapter also covers some applications of audio on the Beagle board, including streaming audio, Internet radio, and text-to-speech. BTW, I am testing this at work with Ethernet connections and a Logitech C920 camera. Oh and if you do not use your USB Fan on the AI, it may get too hot to stay connected. https://www.newark.com/element14/6100310/beaglebone-ai-fan-cape/dp/50AH3704 is the FanCape that one can or may purchase to handle eat transfer.

Thanks for the reply Derek sorry I wasnt clear. add the time, local temperature etc? Thanks. Each chapter in the book links to an individual web page, which can be accessed using the menu on the top right-hand side of this page when you close this menu. Other than the existing robot, we are going to need the additional parts shown below: We are this specific kit to mount the camera to the robot. I can connect to a local webcam with the normal VideoCapture(0) command. capture.open(http://16.86.238.211:8090/?action=stream.mjpg). ~~~~~~~~~~~~~~~~~~~~~~~~~~~ BluPants goal is to make robotics and programming accessible to everyone. unable to lock the administration directory. If you use the OpenCV C++ library you can use the putText() drawing function to add text. Kind regards, Derek. Enjoy your time on Earth! $ lsusb By the way thanks for the nice book. That is interesting as I have not seen it working are you getting a reasonable frame rate? Now, we need to stick our hardware together and make this source run. Hi Derek, First I want to say that your book is great and I have learned a lot about the Beaglebone and programming in general with Linux. I have always been in that group, on both the BBW and now the BBBnot I dont really understand why its working now. Im wondering am I have to do something to export my USB sound card to my QT app like the I managed to connect an old Genius webcam and a Sony Playstation 2 Eye-Toy camera to the BeagleBone Black following this chapter. Please read the section on VNC in the previous chapter and set up a display. For more information about BluPants visit, For this tutorial, we are going to add the camera to an existing claw/gripper robot with the distance sensor as a base robot. However I can see that a udev rule might be in order. BTW, I am trying to run this under the Python interface, but could program this in C and then wrap it. I have tried this command to stream live video from a webcam: ./mjpg_streamer i input_uvc.so fps 30 r 1280720 o output_http.so -p 8090 w ./www. Not wanting to try several different ones though, I just thought Id ask you if youve seen one that works reliably? The advantage of doing this is that you can add your own data processing and controlling functionality into the video display. Kind regards, Derek. Im not sure what I did to GET it working, but its working on the BBB. Thank You Its not a huge deal as a person can simply chown the file(s) as neededbut it might be easier to write a rule and be done with it. 423) and set up port-forwarding on your Internet router. Other than the existing robot, we are going to need the additional parts shown below: to mount the camera to the robot. But this should work for folks using Debian, as long as you make sure to use the correct values for the vendor and product numbers as I noted above. This is from altering the source given which can be firstly found at https://docs.opencv.org/4.3.0/df/d9d/tutorial_py_colorspaces.html for tracking purposes. I do have Qt5 compiled and working, so I might want to simply use thatIm not sure yet. So, if you so desire, get the source at the end of this small presentation, type python in the terminal and see glory at its finest. Then Ill basically start over in this chapter and skim through those exercises again using the BBB and the camera. You can reload the rules without rebooting after you save the file, but that is more of a hassle than its worth sometimesso to be honest, the easiest thing to do is probably just to reboot the machine. The problem I am looking at is how to stream a video to the Beaglebones internal IP port so any computers can log into the Beaglebones IP address and access the video. E: Package has no installation candidate. I am retesting this source and maybe updating it soon! Starting face detection application Hi Dinesh, Im afraid you are straying well beyond the content in the chapter there. That should get us our required software to use for using specific ideas revolving around numpy, matplotlib, and OpenCV.

Use Video4Linux2 utilities to get information from and adjust the properties of video capture devices. It is an introductory video that should give people who are new to this topic a starting point to work from. molloyd@beaglebone:/$ PKG_CONFIG_PATH=/usr/lib/pkgconfig/ Note that they are in Hex. Im trying to compile the code of Figure 12-3, and when I do this, I get the error as follows: Package opencv was not found in the pkg-config search path. I think Im going to write that up as a script I dont trust my students to type that much without a mistake or two. v4l2-ctl: unrecognized option set-format-video=width=640,height=480,pixelformat=1 I reviewed the man page for select and I think its just because select() is timing out (and thus returning 0). There was a major server crash and perhaps this is a casualty. Im guessing I missed something in the install, but Im nto sure what? Meanwhile, I need to install a Qt cross-compiler toolchain here in Ubuntu 12.04LTS. Please do your own due diligence on these products and the retailers that are identified: The Logitech C920 is the preferred USB camera for this chapter, particularly if you wish to perform video streaming applications. Find them at our lessons, Other than the basic drag and drop coding blocks shown, it also natively supports Python for more advanced students. This tutorial shows how to add a camera to an existing BluPants robot. If you look below, you will find the source for your USB Camera on the AI. You should review the materials that are linked at the end of the chapter in particular, the CVOnline materials and the Cascaded Classification documents. It is an expensive camera, primarily because of the fact that it contains a H.264 hardware encoder, which takes the workload away from the BeagleBones processor. Building the OpenCV timing example for the Beaglebone I suspect this is a difference between my sources.list, but Im not sure what I should be pointing at. In all of these examples I used the VLC media player to display the video data. Capture and playback of audio streams is described, along with the use of Bluetooth audio. It was not easy. KERNEL==video0, SUBSYSTEM==video4linux, SUBSYSTEMS==usb, ATTRS{idVendor}==0x046d, ATTRS{idProduct}==0x0821, SYMLINK+=webcam0 The first step is to find a suitable alternative. unable to locate package libv41-dev Hi Derek molloyd@beaglebone:/$ export PKG_CONFIG_PATH When I attempt to do the apt-get, Im getting the error message Package libttspico-utils is not available, but is referred to by another package. On the second question I have never tried to capture a mjpg stream, but make sure that your version of OpenCV has FFMPEG support, as I dont think it is always present. On page 477, you have Subdevice #0: subdevice #0 When I attempt to install the packages (your next step on p. 477), I get two errors: molloyd@beaglebone:~/exploringBB/chp12/openCV$ ./build You could even develop code for capturing multiple streams simultaneously and processing the data for example, for stereo imaging. Buy on Amazon: (, Copyright 2014- Derek Molloy | All Rights Reserved | Powered by, This is the companion site for the book Exploring BeagleBone: Tools and Techniques for Building with Embedded Linux by Derek Molloy. The audio data can be raw waveform data or compressed MP3 data from the board file system or from Internet radio streams. if is a single digit, then /dev/video is used I am trying to capture the resulting video stream with OpenCV.

Kind regards, Derek. Im not sure I put this in a correct place or not. So you can see that it is supposed to recognize the device parameter(s), however it simply doesnt. **************************************** Hi Walt, Very strange! Up till now I have primarily have been a Windows programmer, but getting more into robotics and embedded systems and this book speed me along. Any ideas? Open Source Computer Vision (OpenCV) image processing and computer vision approaches are investigated that enable the Beagle board to draw inferences from the information content of the captured image data. Record audio data using USB audio adapters or webcams. So much to do, so little time. Googling around a bit Ive seen a couple different examples of such a rule for Logitech cameras.

We have a couple of challenges you can do with your new bot. The final part of this video goes on to describe how you can build your own software implementation that can display the data using LibVLC and the Qt framework. By the IP address that you are using, I am not sure that I properly understand the first question now. Because I have the C910 (not the C920) camera, I cannot use the h.264 codecbecause my camera doesnt seem to support it. I was hand typing things, though Ive never had an issue with the ` on plain old linux builds before.I may also try reburning the image in case something got corrupted along the way.
