 早年看到的全景图都是摄影师站在一个特殊的场景，然后用相机环绕一周拍摄的画面，通过软件来生成一张全景图，一般来说它只能够生成360度的画面，如果是720度，那就会把摄影师自己带进去。现在靠无人机升空后悬停拍摄的画面可以达到720度的全景画面，相当有趣，在此与大家分享一组我运用该方法拍摄后呈现的画面。 原来只知道大疆“云”空间上可以达到这样的效果，觉得容易把拍摄的内容外泄，也就没有多大的兴趣，后来蔡老师找到了一个第三方的平台“720云”，这样就开始尝试拍摄这些内容。 大疆的“御”系列就有全景模式的功能，有球形的全景和180度平行全景模式，还有就是广角模式（它可以对着任何角度拍摄，涵盖更多的内容）。这就可以让你尝试不同的视野来记录和观看这个世界。

当你选择了球形的模式后，在无人机悬停时就可以拍摄，不同的高度呈现的效果都有所不同，一般它会自动地拍摄25张不同角度的照片，自动的生成一张看上去像扭曲的全景图，你需要把这张照片放入具备处理这种全景图的软件中，它才会呈现应该有的全景效果。
现在我使用的就是“720云”，它可以让你在该平台上观看各个角度的画面，只要你上传的是原图，其清晰度相当惊人。

当然这个720云APP仅仅给你1.25G的免费空间做这样的尝试和体验，你希望呈现的内容过多或者是你企图通过这个平台来出售你的作品，那就要缴纳会员费，这个会员费要上千元，一般的摄影爱好者恐怕还不会成为其会员。
由于该平台还限制你与浏览者的交流，这样你企图与潜在的购买者交流途径也被切断了。 而且你要成为会员才可以将生成的图片发送到公众号之类的自媒体，否则就只能通过截屏的方式获得较为一般的图像。 2024年无人机新规后，由于报备区域的限制，部分的内容就没法随意拍摄了，还好在120米限高的范围内也是可以有比较奇异的效果，每个无人机爱好者都可以做这方面的尝试。 我的作品都在该网站上：720云VR全景官网-3DVR全景拍摄制作软件平台 (720yun.com)进入后搜索“老寿摄影”即可。
Capturing and Presenting Panoramic Views In the past, panoramic images were typically captured by photographers standing in a specific location, rotating around with their camera to capture a full 360-degree view. Software was then used to stitch these images together to create a panoramic photograph. Usually, these images were limited to 360 degrees; however, if extended to 720 degrees, the photographer would inadvertently include themselves in the shot. Nowadays, with the use of drones hovering in the air to capture images, it is possible to achieve a 720-degree panoramic view, which adds an intriguing dimension to photography. Allow me to share with you a series of images I have captured using this method. Previously, I was aware that DJI's "Cloud" space could achieve such effects, but I was hesitant due to concerns about potential leaks of the captured content, which dampened my interest. However, after being introduced to a third-party platform called "720 Cloud" by Mr. Cai, I began experimenting with capturing content using this method. DJI's "Mavic" series offers panoramic modes, including spherical panoramas, 180-degree parallel panoramas, and wide-angle modes, allowing you to explore different perspectives to document and view the world around you.
When you select the spherical mode and the drone hovers in place, it automatically captures 25 different angles, creating a distorted panoramic image. To achieve the intended panoramic effect, you need to process this image using software designed for such panoramas.
Currently, I utilize "720 Cloud," which enables you to view images from various angles on the platform. As long as you upload the original image, the clarity and detail are truly remarkable.
However, the "720 Cloud" app only provides 1.25GB of free space for experimentation and exploration. If you wish to showcase a significant amount of content or intend to sell your work through the platform, you will need to pay a membership fee, which can amount to thousands of yuan. This fee may deter casual photography enthusiasts from becoming members.
Furthermore, the platform restricts communication between you and viewers, cutting off potential interactions with potential buyers. Additionally, only members can share the generated images on platforms like WeChat official accounts; otherwise, you are limited to capturing screenshots for more standard images. Following the new drone regulations in 2024, certain areas are now off-limits for unrestricted aerial photography due to restricted zones. Nevertheless, within the 120-meter height limit, there are still opportunities to capture unique and captivating images, allowing every drone enthusiast to explore this creative avenue. |
