Chapter 3 Design • In a marker-based AR application, the image you want to recognize is provided and you know exactly about the thing to be searched using the camera’s data (frame). It is like detecting the hard-coded things in your application. • In a position-based AR application, the image is not available beforehand; you have to recognize and identify features like color, pattern, edge, etc., which exist in the camera frame. In this application, different sensors are required to recognize position and orientation. Integration Service Layer After recognizing features and patterns, you need to integrate them with AI-based algorithms along with integration frameworks such as cloud-based integration or ESB- based integration as per your existing application, so that you will be capable of getting data from the existing DXP’s application, as shown in Figure 3-31. Once the features and pattern have been extracted by frame, appropriate programming action can be taken to get the objects on the screen using its camera. Figure 3-31.
