From the point of view of the application, a target is a “map of contrasts” composed of points. Each point is given by the different contrast between the graphic elements that make up the design of the image to be scanned or “target”.
Two equal targets cannot display two different experiences, therefore, an image that is already being used as such, cannot be defined as target.
If you upload duplicate the same image to Studio, at the time of scanning that target, the operation of CamOnApp will be incorrect, preventing viewing the content in augmented reality. The same happens when uploading images with similar designs: the scanner can confuse one experience with another, generating an incorrect operation of the app.
