Creating Custom Adaptors

我们e the Image Acquisition Toolbox™ Adaptor Kit to create an adaptor

The Adaptor Kit is a C++ framework that you use to create an adaptor to support new hardware. The kit is not necessary to use Image Acquisition Toolbox. Use it only if you are writing a custom adaptor.

Functions

`imaqhwinfo`	Information about available image acquisition hardware
`videoinput`	Create video input object
`imaqreset`	Disconnect and delete all image acquisition objects
`imaqregister`	Register third-party custom adaptor
