Sistema radar para reconstrucción de objetos 3D mediante la utilización del dispositivo Kinect.

Abstract

It was designed and evaluate a radar system for the reconstruction of 3D objects using the Kinect device for the research group electromagnetism and microwave that has the faculty of computer science and electronics in Escuela Superior Politécnica de Chimborazo in Riobamba city. The methodology used in this research is exploratory quantitative since it was developed in five principals blocks, representing the processes inherent in the management and use of the information provided by the Kinect device. These blocks are: Capture the Image, Depth Estimation, Store Information, Representing Depth in Binary Square matrices, and 3D Reconstruction. The tools used for the operations of Radar System consists of Kinect device, computer, Open NI controller, and Matlab Software. Experimental results after measurements made with linear objects, determine the estimated depth measurement by the sensor Kinect has a 3 mm Resolution and Object Scanning has an accuracy of 99.88%. Through tests conducted to reconstruct objects in an area (2×2) m2, it was concluded that the maximum distance of the Kinect to Object should be the 1.2m and the minimum distance 0.5m as long as the IR camera is parallel to the axis of the floor. The algorithm implemented in Matlab allows digitizing objects form binary matrix where each element value 1 has a fraction of the object. It is recommended that future research on three-dimensional reconstruction, increase the number of views for making measurements in order to obtain as much data to increase the accuracy in objects reconstruction.
