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 !
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.
OMG,you are my lifesaver,I tried so much ways including pi camera2 face detection program on their official repo but idk it is not working for me,but you are rockingg,Thankyou Somuuchh.If didn't saw this video my last opt was to restart all from 32bit os which will drain my entire work on 64bit.Once Thank you Paul
Thanks a lot sir,. I was trying to connect the camera since last two day, But You code is so simple. I don't know why, But I was not getting any blog regarding the same. Thanks again

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.
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.
Thanks! I love the Raspberry Pi Camera videos with OpenCV. Thank you Paul. Also, I just found a SunFounder Video Robot Car Kit for Raspberry Pi 5 /4/3B+/3B. Python/Blockly (Scratch), Video Courses, Rechargeable Battery (Raspberry Pi NOT Included) Amazon $89.99 This might be one way to learn the RPi5???
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
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!
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
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
Paul just completed 1 thru 44 no issues went great. THANKS Now lesson 45 I installed cv2 as shown in lesson 45 Says sucessfully installed . If type python it says not found. If I type python3 details are show. When I type import cv2 i get the same error as the other student import error can not open shared drives . Please advised im lost. 1 to 44 went great
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.
Great lesson today! Will be working on updating my bullseye and doing homework and getting pico w loaded with micropython. I am up for live stream tomorrow night!!
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.

Hi Paul, the recommended Raspberry Pi kit is not available currently on Amazon. Any other kit you might recommend for compatibility with your tutorials.
Hi Paul, Another high value session. I will be trying to add camera to my current Pico W project and expect this knowledge will be transferrable to Pico. Best regards, Ed
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.
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 .
Hello Paul, Thank you very much for the video. I have a doubt regarding the camera module. 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?
I was confused why the output was lagging on my machine, I recorded it to an AVI file and playback quality was excellent. I assume the lagging I saw while running the code real time was from the VNC viewer WiFi connection.
Hey, i am working in a virtual environment. I successfully installed cv2 library in it, but I am unable to install Picamera2 library. Can you help. Thanks
Hey Paul, I have completed your Arduino series and am now looking to get into this series. I just have one question, can I complete this series with the pi 4 model b or does it have to be the pi 4 model a. Thanks.
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.
So far so good, but what if you use OpenCV to open the camera and grab a frame. Did you find a solution, why it's not possible to use cv2.VideoCapture(-1, cv2.CAP_V4L2)
After starting with a fresh install of Bullseye 64 and installing opencv-python, import cv2 complains about a host of missing dependencies. A few minutes with google shows this to be a common problem but I never found the correct solution. Any help greatly appreciated.
Well that was interesting. Upon making a fresh SD with Bullseye I noticed that there are 2 desktop images, one with security updates and desktop environment and another with recommended applications. On my previous attempt I'd used the first option, now I tried the second option. Bingo!! Everything works just fine. I suppose it stands to reason that importing applications also drags in a lot more python libraries.
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
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??
Hello I tried this but I can’t get a good frame rate even if I lowered my resolution. I get around 20fps when I reduce the resolution to 360x360. Please help me fix this guys. Thanks in advance.
Hello all. All went well with no errors until i type "import cv2" i get " ImportError: libcblas.so.3: cannot open shared object file: no such file or directory" any suggestions
Hi Paul, I wonder if you have a Discord server to get in touch with followers of the channel. They work great to share and ask for help on common topics of interest.
Homework posted ua-cam.com/video/c6Jr0tHpXKc/v-deo.html I also show my design of a holder for the Pi Cam and included the Fusion 360 file in the description. I also added a little show and tell of what I have been up to over the holidays.
Here is link to my homework for this lesson, ua-cam.com/video/5r9Raz-hIlM/v-deo.html. There was a considerable amount of head scratching to get it done. Thanks Paul for doing these videos.
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.
Another great learning exercise, Paul! Here is the link to my homework: ua-cam.com/video/iEcdQCwPulo/v-deo.html I cannot figure out why I am only measuring about 15 fps. I took out the print statement that I was using for troubleshooting, but surprisingly, that doesn't do anything to the fps.
