This disclosure proposes a method and apparatus to facilitate photographing in crowded tourist attractions with Augmented Reality (AR) techniques. By making use of the High Definition (HD) surveillance cameras, an image collecting and operating system on the cloud, and a smart phone connected to the system via WiFi, tourists could freely decide what to include in to-be-taken photos in nearly real-time. They can remove stable obstacles and passers-by from their camera view and expand photos as they need.

Method and apparatus to facilitate photographing in crowded tourist attractions with AR techniques

People always take photos with landmark buildings and scenic spots when they travel to a tourist attraction. By doing this, they want to remember the scenic beauty, to keep a record for memorial recall, and, more important, to share with friends via social media soon! But almost all tourist attractions are very crowded, packed with people everywhere. Hereby you would suffer from 3 major pain points:

1. You don’t want to include a stable obstacle in your photo but it seems no way to work around. You have to either give up the photo composition or think about post process for remedy which calls extra manual efforts. 2. You don’t want passers-by pop up accidentally in your photos. But obviously it is beyond your control, especially in such a crowded place. 3. It's difficult to take a photo of people with the whole landmark building when you stay too close with it or the building is simply too huge to be include in the photo view.

To solve those pain points, this disclosure proposes a method and apparatus based on Augmented Reality(AR) techniques, that is, a cloud-based system for image operating to help users easily remove the stable obstacles in no time, erase passers-by and other moving objects, and expand the photos taken.

The core advantages of this invention: Reducing manual efforts and time for post processing photos. Solving users' pain points and improve user experience with its user-friendly functions. Making fully use of the image/video data collected through surveillance cameras and drive a new service business for tourism industry. 

Basic AR techniques used: There are three major kinds of system compositions for Augmentation Reality, the monitor-based system, video see-through system and optical see-through system. This invention uses the monitor-based system as below.


Work flow for the cloud-based system:


Detailed Description: Given that surveillance cameras are ready and a cloud-based system is set up for collecting and operating images, users could take photos via their mobile devices that is connected to the cloud system via WiFi.
