Where did you get the camera module(s)?
Model number of the product(s)?
What hardware/platform were you working on?
raspberry pi 4 2gb
Instructions you have followed. (link/manual/etc.)
Problems you were having?
I can’t find a system to manually set the focus in a script
The dmesg log from your hardware?
Troubleshooting attempts you’ve made?
I have a script that does a timelapse.
/usr/local/bin/libcamera-still -t 61200000 -o %05d.jpg --timelapse 7000 --immediate 1
I had initially tried giving --continue-autofocus but the result is not acceptable.
rebooting the raspberry or for other random reasons the focus shifts
a solution would be to put
/usr/local/bin/libcamera-still -n -o test.jpg --autofocus
as the first instruction but at night when the timelapse starts there is no light and no good focus
What help do you need?
Is there a possibility to focus via script a certain area of the image manually?
For example if the value 0 corresponds to the minimum distance and 100 corresponds to infinity give via script a focus = 75
or is there a possibility to force the focus to infinity?
You can manually focus as follows:
Step 1. Install the focus adjustment software
git clone https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver.git
Step 2. Open a preview window
libcamera-still -t 0
Step 3. Use our focus adjustment tool
cd Arducam-Pivariety-V4L2-Driver/focus python3 FocuserExample.py -d /dev/v4l-subdev1
Step 4. Press the Up/Down Arrow for focus adjustment, press “ctrl + c” to save, or “r” to
Good morning and thank you for your response. Yes it is a good system but it is not a solution because it assumes c’io have access to the raspberry. To do the first tests it is obviously not a problem but when it is operational the PI with the camera has neither internet nor possibility to access via ssh.
I was hoping there was a system once I found the ideal focus value to be able to put the command directly into the script
Do you mean you want to control the focus manually. Such as by switch ?
At present, we just have this script, I suggest you use another program to call this
script to realize control by another application.
In this way, If the application can start automaticly, you don’t need to access the script via the ssh.
Okay I’ll try this route. Thank you
