Announcing the Most Awesome Raspberry Pi Lessons of All Times! This time we RUMBLE!
In this class series, we will be using the most excellent Sunfounder Ultimate Raspberry Pi kit, available here: (Affiliate Link)
amzn.to/3tSk9Mo
or for our UK friends, amzn.to/3I5d401
In this lesson I will show you how to use the Raspberry Pi camera on the Bullseye operating system, in either 32 bit or 64 bit mode. I will show you how to operate the camera using OpenCV.
If you want to grab those cool little straight jumper wires I am using to keep my breadboard builds neat and clean you can snag a box of them here:
amzn.to/36NyfHq
If you guys are interested in the oscilloscope I am using, you can pick one up here (affiliate link):
amzn.to/3v13Mhl
You guys get your hardware ordered so you can follow along at home!
You will also need a Raspberry Pi. I suggest the Raspberry Pi 4. If you do not already have one, this is the most suitable gear I could find:
amzn.to/3pBMfKm
The Raspberry Pi's are sort of pricy right now, so you can look on ebay or elsewhere to see if there are any deals. You will need a SD card. If you do not already have one, this is a good one:
amzn.to/3KcXTn2
I like using a wireless keyboard and mouse to have fewer wires. You can certainly use your USB keyboard and mouse, but if you want a nice wireless one, this one works on the pi. We demonstrate this by using a button switch to control a LED.
amzn.to/36Rv9Sk
You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

Hi Proff, you taught me a lot back then when I was a fresher in my early career journey, 7 years ago. Now I'm an Electrical/Electronic Engineer working as an IoT/AI Solutions dev and a tutor. Lot of thanks and I salute you !

Well done! Congratulations on your success.

It is great to see the Pi camera come to life! Having done the FPS calculation in the AI course, it was a pretty quick addition to the Pi lesson. I am seeing around 18 FPS. It looks good, but is not the 30 FPS that Paul expected. Thanks for the great lesson Paul!

Excellent lesson. Python would not work until I had to updated my bullseye firmware to get libcamera library by using: sudo rpi-update. Also, updated /boot/config.txt file with the following changes: #start_x=1 camera_auto_detect=1 gpu_mem=256 Found libcamera-hello command was a good way to confirm camera is wired up correctly.

I have followed you loosely on many of your posts. Arduino, Fusion 360, etc. You're an excellent teacher. I find all of your content intriguing and I normally browse your posts as my hobby needs dictate. Thank you for all you do. Unfortunately, I popped into this lesson w/o fully understanding the 64-bit operating repercussions. As a heads up for any of your followers. If they do not install the 64-bit version, i.e. go with default settings on the PI page even though it is a 'fresh install'; they will not be successful in installing the CV-2. At some level I thought the 64-bit vs 32 would just be a performance Hicky...but no...the files structures, etc. are a bit different. Anyway, you earned a Patrion visit from me. Just for the pure tenacity of putting that all together for us. If only I would have popped into lesson 44 1st * smile * . Please keep up the good fight. Rob

Lesson 45 new 64bit Pi added downloads as instructed . Python echoed 3.9.2 cv2 echoed 4.6.0 vcgencmd getcamera returns zeros Run program I get : Traceback (most recent call last): File "", line 3, in File "/usr/lib/python3/dist-packages/picamera2/picamera2.py", line 254, in __init__ raise RuntimeError("Camera __init__ sequence did not complete.") RuntimeError: Camera __init__ sequence did not complete. I even copy paste you program Same thing. Paul love you videos and you are a great teacher. Also configuration on the new 64 bit Bullseye does not show option to select camera , Should it ? Just need someone outthere to point me in the right direction .

I now have three CSI cameras. I tested each of them and the results are listed below. I did notice some lag, but I was using VNC viewer. I dont have a spare screen to verify if that is the cause of the lag. I set the start time prior to the capture statement and the end time after the show statement. I then increment the frame count and add the calculated frame time to the total time. After quit, I divide the frame count by the total time to get the FPS.

Hello Paul. I enjoy your tutorial in this series very much here in Solingen in Germany. Thanks al lot for that. As I'm using Visual Studio Code on my PC, I was very pleased to see that in bullseye this is shown as a Recommended Software. So I installed it and it works very fine with all that very helpfull stuff in programming. It makes coding much easier than in Geany or Thony, which of course I tried as well. Perhaps it's usefull for your community to know that and try that tool. Best regards Bernd

@PM_Ace 6 месяцев назад

Hi Paul, Thanks for the series. Ive learned a ton. One small note to others watching the new 5 pi cables from this kit dont fit a raspberry pi 5 slot as it is to small.

@paulmcwhorter 6 месяцев назад

These lessons are better suited for earlier version of the Pi. The 5 is really trying to become more of a desktop type machine, and less of an embedded platform. Maybe pickup a used, earlier version of the pi for the class.

@PM_Ace 6 месяцев назад

Thanks for the response! I have enjoyed the class a lot and learned a ton. Would a raspberry 3 work for this class or only a 4? Thanks!

Hello Paul. Firstly thank you for putting on these great tutorials. I am having a problem with lesson 45, Getting some errors when installing opencv. Is there somewhere I can go to get assistance? Thank you in advance. Vic

@floridian080 Год назад

on the fps script, I had to remove the line picam2.preview_configuration.controls.FrameRate=30 to obtain the video with FPS. I am using the USB camera from your previous AI series on the pi400 and obtain FPS of about 20.

Think I got the home work. I also tried different resolutions. When I went to 640x360 seems to slow my fps but not as much as 1920x1080. Thanks for this lesson.

So, I am trying to use ROS on Raspberry pi to build a RC Car due to which I had to install Ubuntu on my Raspberry pi. However, the camera that I have (Freenove 8MP) does get detected by Raspberry pi but does not capture any frames. Can you please assist what I should do in this case?

Hi, Many thanks for one more excellent tutorial. I have followed the instructions using the Raspberry Pi HQ camera. It all works smoothly, however, it looks like the Red and the Blue channels are interchanged. Blue things look Red, Red things look Blue, and Green things look Green (as well as white). Looks like an RGB BGR issue. Do you have any idea what's wrong? Thanks. Nahum Budin.

@budinnahum9081 Год назад

To prove the interchanging, the following fixes the display: frame[:, :, [2,0] = frame[:, :, [0,2]]. Nahum.

I fired up a new my newly delivered RPi 4B today. I tried to install opencv as I did last on my older 4B running Bullseye and it didn't work. A newer version of opencv is available. I installed opencv without specifying the version number and I didn't get any errors installing it. pip install opencv-python

@paulmcwhorter Год назад

The possible issue will come in that we will be on different versions of opencv, and will my future demos work on your version. I would really try and see if you can get my version installed, that would be safest.

A shift to Python from Debian Linux enabling expanding market for Pi Camera for the several knock-off SBC on the market today. RaspberryPiOrg, et al, showing lack of loyalty by not including the breadth of required code to operate PiCam with Bullseye before its release.🤬 Backward compatibility is a fable. looking anxiously for saving video to file??

@paulmcwhorter Год назад

James, nice work, but I think you are not getting an accurate number. There are lots of lines of code not between your two measurements of time. You need as much of the loop code as possible between these two lines of code, as each line takes some time to execute, and hence code not between your two time measureuments are not being accounted for. Nice work, think on it a little more.

@DrDave327 Год назад

I took out the print statement that I was using for troubleshooting, but surprisingly, that doesn't do anything to the fps.
