The resultant imagery is convincing to the audience because the perspective is consistent throughout the footage and matches up to the camera's movement.
Video editors and visual effects artists use this information to seamlessly composite effects into their video. Once the 3D camera tracker solves the geometry of the scene, it is able to estimate the position of the camera that shot the scene and various planar surfaces that relate to the tracking points. It then takes the data from the various tracked points and is able to solve their spatial relationship based on the 3D geometry of the points' positions. 3D camera tracking works in much of the same way, it tracks points within the video image and measures how those points change over time. Perspective relates to how objects are arranged and spaced in three dimensions.Īs visual perspectives change for an audience, they are able to better interpret and perceive 3D space from the flat image. One of the best ways to understand 3D space in a 2D medium is to visualize and track movement. Oddly enough, the human brain is able to extrapolate 3D space from two dimensional images, like video. Perspective helps make sense of the world. Distances are judged and the size of objects are estimated as a result of perspective. Perspective relates to how objects are arranged and spaced in three dimensions. People are used to seeing things within space, through perspective. Now a video editor can perform 3D camera tracking on POV shots using the everyday tools that are at nearly anyone’s disposal. Camera tracking used to be a specialized task, one that only a select few could pull off.
3D camera tracking is a technique that helps the video editor put things into perspective and alter the reality of the audience. Applications such as Adobe After Effects provide all the tools necessary to generate amazing work. The video editor is more responsible now than ever before, for creating dynamic motion graphics. That same object can be a simple illusion, one that's created through perspective. An object positioned with the correct perspective will appear firmly locked into reality. Yet perspective tricks the brain unlike anything else. The common high-precision optical positioning system is also very difficult to meet the requirements.Small, wearable action cameras put things into perspective.
In order to meet the customer's very strict requirements for the stability of position and attitude measurement and data output, it is often necessary to achieve 0.00001 data stability.
