Math and Modeling for Camera Developers
Abstract:
Modern cameras are sophisticated devices that rely on a combination of intricate hardware and complex software algorithms to produce high-quality images. Understanding the underlying mathematics and modeling techniques is crucial for camera developers to optimize performance, correct imperfections, and deliver exceptional image quality. The Camera2 API exposes many of these details and developers would benefit significantly by knowing how to work with them.
This talk will delve into :
- Camera intrinsics and extrinsics, which describe the geometric relationship between the camera and the scene.
- Lens distortion correction using the Brown-Conrady model.
- Meaning of various maps exposed in the Camera2 API such as hot pixel map, lens shading map
- and more
Target Audience:
Android developers seeking to build or enhance camera-centric applications. Especially those who are building apps seeking to use cameras on Android to understand the world around them, eg: AR based apps
Takeaways:
By the end of the talk you will have a good understanding of the mathematical models needed to process images captured by your Android device's camera and use them for innovative applications.
