Comments on Gigapan: Shanghai Skyline - Stitched From 12,000 Pictures - 上海风景线 - 由12000张图片拼成

    Go to page:

  2. Shanghai, one of the most populous cities in the world, has never been pictured in such enormous detail. Let the world experience this fast growing city and understand China is always my dream. Through my telephoto lens, I wish you, the viewer, can blend into the daily life in Shanghai and enjoy your virtual visit. ...

    Just post a few more images, you may find them at www.gigapan.org/profiles/27638/ . A sister image to the Shanghai Skyline is www.gigapan.org/gigapans/90577/ (Beijing Residential Area). I also put a great wall image at www.gigapan.org/gigapans/90650/ .

    I recently post 14 new panoramas taken in Hawaii. www.gigapan.org/profiles/27638/

    Alfred, I just want you to know that I show this image to people everyday on my iPhone, and I get gasps everytime I zoom in on the car's license plates and read the brand of AC units in the apartments. People love it! That's the bottom line. Congrats and thank you for the great work and great sales tool for my own imagery. Cheers!

    Hi, this is an enormous achievement as such. my question is: what's the ambition to go further and further in the number of images, since we obvious hit limits due to the available time to consider it being ONE session on location. My understanding is: this will lead to either much faster image capture requirements OR to a new idea: instead of doing everything to get the light conditions homogenous during a session - why not allowing it to change radically and thus show in ONE stitched image the lapse of time and changes in light conditions. This could be also done using individual images stitched later on like in time-lapse. The new firmware if EpicPro supports this and I'm looking forward finding first examples. Briefly: discovering the opportunities provided by EpicPro and the tools is still in progress - we can all still discover something new here. Kind regards Thomas

    Great accomplishment. One thing I have been struggling with is getting good image quality when using either a 400mm with 2x extender or a 200 mm with a 2x extender. Because many panoramas need an extended DOF I've had to stop down to f32 or even f45 to get all the foreground and background sharp. Because of this I've had to use a slower shutter speed and high ISO resulting in poor image quality. I shoot with the 7D BTW. What settings did you use for these shots? Also I have considered shooting left to right and pausing to adjust focus as the rows move down. Have you tried this at all? Once again great work!

    chtseng, You really need to brush up your geometry. The overlap region is still in the picture, they are not simply gone. Therefore, the way you calculate the image size is completely wrong. People will be laughing at your post.

    hi Alfred sorry, I think the correct arithmetic should be: 12000 * 18M * 0.25 = 54G pixels because there are 4 regions (top, bottom, left & right areas) need to be overlapped. Which means, 1 photo only contribute 1/4 area for the panorama if overlap ratio is 0.25.

    Alfred Zhao (February 14, 2011, 07:49PM )

    chtseng, Don't take it as an offense, you will need to catch up some basic geometry. Based on your model, the number should be 12000 * 18M * (1 - 0.25) * (1 - 0.25) = 121.5 G pixels. A more accurate estimation is 112G pixels. The discussion in this thread is about should people alter experiment data or not. Different model may yield different estimation, therefore, estimation should not be used to manipulate output. Anyway, I had enough discussion with a lot of people already. BTW, gigapan uploader does not have problem reporting the uploaded pixels. This is a known fact.

    hi I think that GigaPan uploader has error on calculating the pixels for images stitched by autoPano Giga software. if photo's overlap ratio is 25%, then actually only 1/4 center area is used ( deduct top, bottom, left & right , each has 25% overlap). 12000 photos x 18000000 pixels x 25% is 54000000000 pixels, about only 54 Gigapixels.

    So engrossing! I wouldn't want to visit a city again without first exploring a Gigapan.

    The un-cropped version is also uploaded and can be found at gigapan.org/gigapans/e2d7089560f22b decf8a3715ea65f762/ . The upload is intended to help testing the new gigapan uploader.

    关于PTGUI，在做大图的情况下，基本上是不可行，Gigapan的自带拼图软件可以拼接2000张或以 下的图片，更大的需要用Autopano。无细节的图片，由于拍摄顺序，可以直接放到它相对应的位置上，我 提到的这两款软件都能做到。至于购买Gigapan，你可以直接在Gigapan的网站上定，他们可以发货 到中国，不过你可能需要能直接付款到海外的信用卡。或者你可以请海外的可以信赖的朋友帮你定，然后寄给你。

    For English viewers, the question was about the shooting sequence. To avoid problem due to shade, I used column-first shooting order. Even though row-first order may be more stable, the resulting un-even shade will be very difficult to process.

    Gigafoto, 为了避免阴影，我采用的方法是向北背南，自西向东，自上而下，以列优先拍摄的。这样，就有效的避免了阴影的 问题。当面向正南正北时，自西向东的列优先比较合适。当面正西时，自上而下的行优先比较好。当面向正东时， 也是行优先，不过，开拍时间要上午稍晚一些。其他方向，需要更具体的分析了。

    How to buy the GigaPan system in China? Help me please，Thanks! Alfred ，你是怎么订到　GigaPan system　的，在国内有技术支持吗？我的英语很差。如何购买？帮助我，谢谢！ Alfred ，＂上午8:30分开拍，平均2.4秒一张图片，我拍摄了12000张，并且在下午4:30分结束。＂ 请问：你是否面向南背北、至西向东、由上至下拍摄的，还是面北朝南、由西向东、由上往下拍摄的？因为这么长 的拍摄时间，阴影变化问题是很难处理的。谢谢！
