Panorama Stitching
Panorama Image Stitching
Combining multiple overlapping photographs into a single wide-angle or 360-degree panoramic image.
技术细节
In digital imaging, panorama stitching plays a critical role in how images are stored, processed, and displayed. Modern image pipelines handle combining through standardized APIs (Canvas, WebGL, ImageBitmap) that operate directly on GPU memory for performance. Understanding panorama stitching is essential for optimizing web delivery, where image payload typically accounts for 40-60% of total page weight. Browser-based tools can manipulate combining entirely client-side using the Canvas API without server round-trips.
示例
```javascript
// Panorama Stitching: processing with Canvas API
const canvas = document.createElement('canvas');
const ctx = canvas.getContext('2d');
ctx.drawImage(sourceImage, 0, 0);
const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
// Process pixels in imageData.data (RGBA array)
```
