Hello everybody, I'm posting here a question I have. Indeed, I'm working on a project using OpenCV and I would like to know some tips. I want to register a set of images with regard to a reference one. Each image already has a set of point I've computed (I used a homemade algorithm to find out these points. In fact, these points are the stars in astronomical images) and I take an image as reference.

Now, I need to match these dataset in order to compute for each image :

• the (x,y) shift

• the rotation angle

Could you give me some advices ? I think that OpenCV must have some good functions but I'm not sure about it.

Best regards,

The different sets don't have necessary the same number of points between each others and the number of outliers can be important
