Hello Thilo,
First of all, to control the frame grabber from within LabVIEW, you will need to speak to the manufacturers of the frame grabber about getting a driver which you can access from within LabVIEW. I've had a look on their website and they do sell a DLL which you can access from within LabVIEW. How much functionality this has I dont know.
To then process the images using the Vision Development Module you will need to first convert the image into an IMAQ image, this is discussed in the knowledge base article linked below.

This will probably be quite a drawn out process that will involve a lot of programming, and may also reduce the acquisition times available to you. If you want to use LabVIEW and the Vision Development module I would recommend that you take a look at the NI Frame Grabbers available. If you have a DVC 1310AM or a DVC 1310AC then either the NI-1422 or the NI-1424 will work with these cameras. Take a look at the following links for more information on these products.

Having an NI frame grabber will allow you to use the NI-IMAQ driver and will make the integration of capture and analysis a lot smoother and easier for you.
If you require further information, please post back and I'll try to answer your questions.
