How to realize REAL TIME IMAGE STITCHING

OpenCV functions are not optimized for real-time image stitching with multiple cameras. The document introduces how to optimize OpenCV for this application by fully processing the stitching module on the GPU rather than partially on the GPU and CPU as the default OpenCV implementation does. A demonstration is then provided of the optimized GPU-based image stitching in real-time.

How to realize REAL TIME IMAGE STITCHING
- 1. How to realize REAL TIME IMAGE STITCHING with multiple camera Hiroshi Matsuoka
- 2. Open CV is a collection of general purpose image processing functions. However, it does not mean those functions have been well optimized.
- 3. Here, I will introduce how to optimize OpenCV for real-time image stitching.
- 4. Stitching module of OpenCV uses GPU partially(left). So, I optimized to process fully on the GPU(right).
- 5. Conclusion • OpenCV functions are not well optimized. • For particular application, you must optimize it. • Cult of the GPU!
- 6. DEMO
