You will have to give at least one argument: the path and name of the file to store the picture. You can use the capture() function from the camera object to take a picture. camera.capture("/home/pi/Pictures/img.jpg") If you want to see the difference, you can try commenting that line, and you’ll see that the quality of the picture we take is not that great – because the camera did not have enough time to adjust to the brightness and other characteristics of the room. That’s why we are then waiting for 2 seconds, before we do anything else. When we create this object, the camera will start initializing itself. Then we create an object from the PiCamera class. We are going to use that class to get access to the physical camera. from picamera import PiCameraįirst, we import the PiCamera class from the picamera module. from picamera import PiCameraĬamera.capture("/home/pi/Pictures/img.jpg") Here’s the Python code to take a picture with the Raspberry Pi camera, using the picamera library. Open up an IDE, such as Thonny Python IDE, or any other IDE/text editor of your choice. $ pip3 install picamera Take a picture with Python and picamera First make sure you have pip3 available on your environment, and then install the picamera module from pip3. You are learning how to use Raspberry Pi to build your own projects?Ĭheck out Raspberry Pi For Beginners and learn step by step. If, however, you get an error such as ” ModuleNotFoundError: No module named ‘picamera’ “, you’ll need to manually install the module. If you don’t get any message when you press ENTER, it means that everything is fine and you can use the picamera module. To check if the picamera library is installed, open a Python Shell (either from the Thonny IDE, or simply type python3 in a terminal), and execute import picamera. Python3 is the default, you can also use the Thonny IDE for Python, and the picamera Python library is installed. Then, if you have installed Raspberry Pi OS, everything is already configured for you. If you haven’t done that yet, check out this Raspberry Pi camera tutorial where you’ll get all the setup steps, as well as a tour of the raspistill terminal command.

It installs it to F:\Thonny\user_data\plugins\Python38\site-packages and didn't work. I have tried in using Thonny's manage packages window and clicking the 'Install from local file' with a. I have tried adding the '' or '' to F:\Thonny, F:\Thonny\Lib\site-packages, and other places in to no avail. I have tried dragging the GTK3 complete file and the individual \bin file from GTK3 to F:\Thonny\Lib\site-packages. Then ran the same code in VSCode (Windows10) and it worked, but I can't get it to work with Thonny. Additionally, _library() did not manage to locate a library called 'gobject-2.0-0'Īfter downloading and running GTK3.exe I added the \bin file from GTK3 to PATH. OSError: cannot load library 'gobject-2.0-0': error 0x7e.
