A few years ago it was fascinating being able to take videos or pictures with your mobile phone, virtually anywhere. The camera of your smartphone is already used everyday for all the activities that we want to capture in our mobile memory. Now What else can our mobile camera do apart from taking photographs or videos, which will often change our view of things and has a useful or perhaps less banal use?
The group of Advanced Technology and Projects (ATAP) before Motorola Mobility and now Google, are responsible for developing what is known as Project Tango or Tango Project. Tango project entails one way or different perspective to appreciate spaces or objects with your camera. Exclusively for smartphones with Android platform and other devices powered by Tango project, have visual information in real time on all around you; Captures your environment through 3D movements, thanks to the depth sensor. Guides your movements observed through a 3D map and map these spaces in real time.
Basically it is to recreate or map our environment, all in the quest to improve and create a more realistic experience in the recreation and appreciation of these maps. its obviously not as basic as it sounds.
Constructor is the name of the application that is responsible for creating the map or the surfaces taken by our device.
As mentioned previously, it reproduces the image in 3D and in real time, which helps making you appreciate and better manage the movements and approaches for doing so, in addition to understand your position in relation to all around you.
Now we‘ll explain how to use the application and that it should be taken into account during the process.
To take, save and export “mesh” 3D which you have taken, it is necessary to possess a android mobile or acquire a specific tablet of project tango.Subsequently, installing the application ‘Constructor’ from Project Tango. Here I leave the link:https://play.google.com/store/apps/details?id=com.projecttango.constructor
Download the Application, open the application and focus the camera at what you want to scan; make sure that the lighting is adequate during the process of scanning and taking certain meters of distance with respect to what you want to scan. It is worth noting that the Builder application was not designed to capture small objects. Dark objects or causing reflex nor appear during scanning, remember this at the time of the scan.Constantly moving your device, do it at a moderate speed and doing it at different angles, so that this capture spaces and their different perspective with a more precise focus on the area. When you are satisfied, press pause to complete and select Save in the upper side of the screen.Already stored ‘meshes’ on your device can be accessed by just opening the application.
To scan dynamic scenes there is not much difference; moving will capture and then create a static vision of the scene.
If you want to export 3D maps. first enter the application, then at the top right of the screen select export; type the file name and format. This infact will begin exporting, when the process is complete you will receive a notification in the Android status bar.
The format used for files is currently Wavefront, one of the very common format for these type of files in 3D.
You can see that constructor is not difficult to use. You only need the technology required to turn your scans.
Contributions to the project:
Project tango is another way to observe your surroundings; your room, your House towards objects, or measures of your floor. Everything that is part of our daily lives can be seen through, and otherwise, with the eyes of Project Tango.
If you want to be part of the development of Project Tango, join other developers who are working on the creation of applications for the project. It is only necessary to buy a Tablet; an Android device that has a camera, depth sensor and a sensor picks up movements in real time. And the respective development kit; software that expose the motion tracking and learning in the area.
Then it is recommended to get the introduction on the main three technologies used in Project Tango, to subsequently learn in detail about the implementation in this technology on tracking movement, capture of depth and learning area.
Guidelines for the integration of applications created with the Java API with standard Android can be obtained. In the same way for the use of the C API;allowing flexibility at native level. And references for specific statements of unity3D. Among other tutorials and concepts that you serve on this task, everything on the main page of the project.
