谷歌研发超高像素相机以保存名画

【谷歌研发超高像素相机以保存名画】谷歌文化学院研发出一款名为Art Camera 的超高像素相机,帮助世界各地的博物馆以电子版保存馆内收藏。与其他扫描仪器相比,该相机操作更简易、工作效率更是提高了十几倍。使用时,只需将相机正对画作并设定扫描范围,相机即可自动工作并将数据上传至服务器。

In its first five years, the Google Cultural Institute scanned and archived 200 works of art in super-high-resolution gigapixel images. Now in just the past few months, it has managed to scan another 1,000.

The sudden expansion is thanks to a new camera developed by Google, simply called the Art Camera. It's designed to be far simpler to use than other camera setups, making it easier for museums and other institutions to start digitizing the art and documents in their collection. And critically, it's also much faster.

"The capture time has been reduced drastically," says Marzia Niccolai, technical program manager at the Cultural Institute. "Previously it could take almost a day to capture an image. To give you an idea, now if you have a one meter by one meter painting, it would take 30 minutes."

After a few years of work, Google has built 20 units of the Art Camera and is lending them out for digitization. The camera works like this: it's set up in front of a wall where a painting is hung; its operator then points the camera at each edge of the image; once the camera knows how big of a space it's working with, it'll set off to work, automatically moving inch by inch, taking extreme closeups. Those closeups are then sent off to Google's servers to be turned into a single gigapixel file, ready to look at just a few hours later.

Prior to the Art Camera, either the Cultural Institute or the organizations it worked with had to pay to bring in a third party with image-scanning equipment. Now that Google has its own cameras, the process also becomes much cheaper. It isn't charging organizations that want to use the camera, encouraging them to take advantage of it. Niccolai says that the Cultural Institute has already lent it out to organizations across the globe, including in Brazil, India, and Hong Kong.
