Hi Matt,
There are a couple of ways you can go about doing this.
Most webcams will come with some kind of API, usually in the form of a C based dll, which you can call from LabVIEW using the call library function node. This should be fairly straightforward, depending on the number and complexity of the functions you need to use.
The best place to look for more information is the forums, as there are many users out there who have done something similar in the past, perhaps one of them will give you more information based on their own experiences.
