Tried it but due to different illumination the delate/erode parameters have to change for some images, thats not very convenient for my task.

No, different cameras and focal length.

Thx Steven, but detecting only the red ones is not my problem. I need the coordinates from all 110 LEDs no matter if they're on or off.

Hey guys,

im working on a project (Qt & C++) to detect an 10x11 LED array in an image. I need the (center)coordinates from each LED to measure the time. I tried several methods (HoughCircle, contour detection, blob detection) but non of them is robust enough to detect all 110 LEDs due to changes in illumination, reflections on the LEDs and noise in the image. Has anyone an idea how to deal with this?

My image roi looks like this:
