Image augmentation enables you to specify a reference 2D image over which digital content such as images, videos, 3D models, sounds and buttons can be displayed in viewer’s environment. These augmentable 2D images are termed as tracker images.
A tracker image is used to create an interactive augmented reality based experience in which viewers can interact with multiple types of digital content placed over and around the tracker.
Tracker image should follow the rules mention below:
- Image file size should be under 3mb.
- Augmented Images supports JPEG file format only. Avoid heavy compression for best AR performance.
- Detection is solely based on points of high contrast, so both color and black & white images are detected, regardless of whether a color or black & white reference image is used.
The augmentation level of an image is indicated by ★ to ★★★★★ depending on the recognizability and traceability. An image rated as★ will not be easily recognizable which means that as the number of stars increases, the number of feature points extracted are greater. Therefore, it is recommended to use images with high levels of features to achieve a better augmentation level. Images that do not have much feature points may not be recognized as augmentable images by the server and you may need to upload another.
Here are some tips for uploading a high feature point augmentable image:
- Use images which are not simple and unbalanced
- Avoid using images with sparse features.
- Avoid using images with repetitive features.
- Use images with variety of faces and lines that are evenly spread out to enhance feature points.
- User high quality images as low-graded images lower the augmentation performance and experience quality.
