Tracking for Projector-Camera Systems

When you're looking for a Tracking for Projector-Camera Systems, there are many factors to consider. In this comprehensive guide, we will break down the important features and specs so that you can make an informed purchase. Plus, we'll provide some tips on how to use your Tracking for Projector-Camera Systems once you've bought it!

Projector-camera systems may be used to create projection mapping and display information that is directly connected with the physical environment. This is advantageous in a variety of scenarios, for example as a method to enable robots to communicate their goals correctly into functioning settings, as a tool to improve medical techniques by projecting extra data, and as a way to interact with objects using spatial user interfaces such as in industrial visual inspection situations.

Object tracking using projection distortion

If the physical and virtual objects are well aligned, object tracking maintains the illusion of a more prominent target item in dynamic scenes. Traditional trackers based on texture or contour data, on the other hand, are frequently distracted by projected content and hence fail to function properly. We propose a model-based tracking technique that takes advantage of projected content for pose estimation in a projector-camera system. The method of estimating the position of a figure based on visible disturbances is called iterative pose estimation. In a closed-loop, the corrected pose allows for the next frame's projection to be updated. 

Synthetic frames mimicking the model's projection are rendered, and an optical flow-based method is used to minimize the disparity between the calculated and camera images. A difficult radiometric calibration can be avoided because the thresholds automatically adapt to the synthetic image. The GPU-based pixel-wise linear optimization is intended to be straightforward to set up. Our method can be integrated with a traditional contour-based tracker and may be used on other problems, such as the estimation of the extrinsic pose between projector and camera. The video below shows how the 3d posture of moving object is estimated based on the projection's distortion, which is then corrected to match the object's surface.

Projection plane tracking on a markerless closed-look projection surface

Recent developments in mobile projectors' miniaturization are allowing for new forms of information presentation and interaction. Projectors may simply be transported about freely by people or autonomous robots. This technology is able to track the orientation and position of the projection plane only by analyzing the distortion of the projection without regard for any presented content. This enables distortion-free projection using a fixed metric size for moving projector-camera systems.

AR Framework

An augmented reality (AR) software that includes the integrated machine learning algorithms has been built using a closed-loop projection-based object tracking. The program allows you to develop and customize AR environments, perform real-time pose estimation, and provide a webSocket connection to communicate with other sensors in a multimodal system.
