最大全景图像 – 2 太像素
Largest panoramic image – 2 Terapixels

这张图片令人惊叹,拥有2万亿像素——超过2太像素——细节极其丰富,可无限放大。要完整显示它,你需要一个大约相当于23个足球场的屏幕! 它的规模巨大:比世界上最大相机拍摄的图像大626倍,包含的像素是Full HD屏幕的100万倍,或4K显示器的25万倍。 如果每个像素都是一平方厘米,它们将延伸超过20,484,321公里——足以绕地球超过511圈,或到达月球53次。即使只看每个像素一秒钟,也需要大约65,000年——比整个人类历史还要长!

挪威霍门科伦的2太像素全景图像(holmenkollen360.com)链接在Hacker News上分享,引发了关于其可访问性的讨论。用户们承认了这项技术的成就,但许多人批评网站在缩放仅几秒后就激活的付费墙。 一些评论者表示,在不了解完整缩放范围的情况下不愿付费,建议在要求购买之前提供预览。一位用户找到了图像数据的直接链接,而另一位用户认为2欧元的费用作为无广告体验是合理的,甚至建议需要更简单的微支付系统。总体情绪倾向于欣赏这项技术,但由于限制性的访问模式而质疑用户体验。

The image has a resolution of 2 297 216 × 891 702 pixels, which equals about 2 trillion pixels. The exact number is 2 048 432 101 632 pixels. That’s roughly 2 terapixels, or over 2 000 gigapixels – an extremely detailed image where you can zoom in very far.

Compared to PC-monitor:
If this image were displayed on a standard PC monitor, the screen would need to be about 650 by 250 meters (2130 × 820 feet) in size — large enough to cover 23 FIFA-sized soccer fields.

Compared to world’s largest camera module:
The world’s largest camera module, used in the Vera C. Rubin Observatory, is about the size of a small car, weighs 2 800 kg, and captures stunning 3 200 mega pixels per image. This panorama is 626 times larger.

Compared to Full HD display (1920×1080):
A typical Full HD screen has about 2 million pixels. 2 trillion / 2 million = 1 000 000 times more pixels. You would need 1 000 000 (1 million) Full HD screens to display the entire image at once.

Compared to 4K display (3840×2160):
A typical 4K screen has about 8 million pixels. 2 trillion / 8 million = 250 000 times more pixels. You would need 250 000 4K screens to display the entire image at once.

Compared to distances:
If each pixel were 1×1 cm and you placed them in a single line, the total length would be 20 484 321 kilometers.
That’s enough to:

  • Circle the Earth more than 511 times, or
  • Reach the Moon about 53 times.

Compated to time:
I you watched one and every pixel for 1 second, it would take you 2 048 432 101 632 seconds ≈ 65 000 years to watch the whole panorama. That’s longer than the entire span of human civilization.
