Raspberry Pi 4 & Raspberry Pi 5
RPi IR-CUT Camera, Better Image in Both Day and Night(5 megapixel OV5647 sensor)
If you have a little headache with cameras and PIL libraries, try that below steps in order .
Python Camera Test Code
#
import tkinter as tk
import subprocess
from PIL import Image, ImageTk
# ozgurcinar@gmail.com
# mdemirkiran@hotmail.com
def run_rpicam_hello():
# terminal subprocess ile calis
command = "rpicam-hello -t 0 --qt-preview --shutter 3000"
process = subprocess.Popen(command.split(), stdout=subprocess.PIPE, stderr=subprocess.PIPE)
# komut sonucu oku
output, error = process.communicate()
# ciktiyi goruntuye donustur ve tkinter penceresinde goster
img = Image.open("output.jpg") # output.jpg olarak kaydet
img = img.resize((640, 480)) # cozunurluk ayarla
photo = ImageTk.PhotoImage(img)
label.config(image=photo)
label.image = photo
root = tk.Tk()
root.title("rpicam-hello - Orman Gezer")
button = tk.Button(root, text="Kamera Ac", command=run_rpicam_hello)
button.pack()
label = tk.Label(root)
label.pack()
root.mainloop()
Raspi 4 and Raspi 5 and Camera exactly run with that steps.
I prefer that fresh installed Rasbian OS. I have chose 32 bit mode beacuse of 64 bit is still does not have correct driver or I couldn’t manage 64 bit OS and Camera .
Here are magical steps in order to use camera and PIL library on Raspberry pi 4 and Raspberry pi 5
- Create a virtual environment and activate it
ozgurcinar@raspberrypi:~ $ python3 -m venv myenv
ozgurcinar@raspberrypi:~ $ source myenv/bin/activate
(myenv) ozgurcinar@raspberrypi:~ $ pip install Pillow
(myenv) ozgurcinar@raspberrypi:~ $ pip install –upgrade Pillow
- Attach virtual env
echo $PYTHONPATH (empty result)
echo $PATH (check from result if path attached or not)
export PATH=/home/ozgurcinar/myenv/bin:$PATH
echo $PATH (check from result if path attached or not)
- Attach the packages of virtual environment with Python
import sys
#sys.path.append(“/path/to/your/virtualenv/lib/python3.x/site-packages”)
sys.path.append(“/home/ozgurcinar/myenv/lib/python3.11/site-packages”)
- Update and re-install somethings 🙂
(myenv) ozgurcinar@raspberrypi:~ $ sudo apt-get install python3-tk
(myenv) ozgurcinar@raspberrypi:~ $ sudo apt-get install python3-pil.imagetk
