How can I capture image using corp area and check if its correct image type?

Hi,

I need to implement your our camera mode to capture and image in corp mode. I need to set capture area, so user centre a item and capture the image. Then I need to use like ML Kit to see if the capture image item its a expected type. Example; I need to send my idcard to bank. I need to use "app" in capture button navigate me to another page (image corp page) in there there is a image area (corp area) so I can centre my idcard and capture image. But before I send I need to check if it is the correct type idcard. (I don't want user to take a picture any other card, text, image or item). How can I capture image using corp area and check if its correct image type?
