The global shutter camera returns a blurred image. [closed]

0 votes

I bought a new global shutter camera. I used the following command line to obtain images

guvcview -ao none -f YUYV -x 640x360 -d /dev/video1

It returns a blurred image like this. Is this normal?

you need to adjust the lens to the viewing distance you need. Note that the lens also has a lock ring. So:

- first unscrew the lens a bit

- then turn the lock ring so that it moves towards the front of the lens

- then screw the lens + ring in until things are in focus

- then hold the lend and just turn the lock ring until it touches the mount of the lens. The lock ring will then prevent the lens from turning due to vibrations and such.

also note that there are two demo modules for the IMU which are not enabled by default:



to enable them, edit JEVOIS:/config/videomappings.cfg and search for DemoIMU and remove the # character in front of the two entries. This is very easy to do if you get JeVois Inventor, then use the 'config' tab to edit that file.
