A planar target is a flat surface that is designed to be recognized by image recognition systems. These targets are often printed patterns, QR codes, or images that can be easily detected by cameras and sensors. They work best when the angle of view is straight on and without any distortion.
A 3D target, on the other hand, refers to any object or surface that has depth and volume. These targets are often physical objects, such as toys, sculptures, or models, that can be recognized from multiple angles. 3D targets can be more complex for image recognition systems to interpret due to their varying shapes and forms.
One of the primary advantages of planar targets is their ease of use. They are simple to create and can be printed on various surfaces. Additionally, planar targets typically require less processing power for recognition, making them ideal for mobile devices or applications that need rapid scans. Their flat design allows for precise tracking as well.
3D targets offer the opportunity for richer interactions in augmented reality (AR) applications. Because they can be recognized from different angles, they allow for dynamic user experiences. They can create a more immersive environment as users can move around them and engage in a more realistic manner. Moreover, their unique shapes can facilitate more engaging content, attracting users’ attention.
Planar targets are best suited for applications where quick scanning and recognition are essential, such as in retail for product scanning or in educational settings for easy access to interactive content. 3D targets shine in immersive environments like gaming and AR applications, where users can explore and interact with objects in a more realistic way.
Your choice of target largely depends on the objectives of your project. If you need rapid recognition in a controlled environment, planar targets would be ideal. However, if you’re aiming for a more engaging and interactive experience, particularly in AR or gaming, 3D targets will likely serve you better. Assess your goals, the user experience you want to create, and the resources you have available to make the best decision.
