No. of bitstreams: 1 LuisEnriqueOrtizFernandez_DISSERT.pdf: 11059946 bytes, checksum: bdd41462c0c6560f2ac2ded683b3e6b2 (MD5) Previous issue date: 2017-07-05 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Na vis?o artificial usam-se v?rios dispositivos como o MS Kinect v1/v2, as c?meras est?reo PG Bumblebee XB3 e a Stereolabs ZED, entre outros. Como todos s?o dispositivos que estimam dados de profundidade, podem conter erros. Neste trabalho, apresenta-se o projeto e implementa??o de um m?todo gen?rico para a estima??o do erro RMS em dados de profundidade fornecidos por qualquer dispositivo, capaz de gerar dados do tipo RGB-D, isto ?, uma imagem e um mapa de profundidade ao mesmo tempo. Para verifica??o do m?todo foi constru?do um sistema embarcado baseado na placa NVIDIA Jetson TK1 e tr?s sensores, as duas vers?es do MS Kinect e a c?mera est?reo ZED. No momento da coleta de dados foram estabelecidos os modelos matem?ticos do erro RMS para cada dispositivo e, ao final, foi feita uma an?lise da exatid?o de cada um. / In the artificial vision are used several devices like MS Kinect v1 / v2, the stereo cameras PG Bumblebee XB3 and Stereolabs ZED, among others. Because they are all devices that estimate depth data, they may contain errors. In this work, we present the design and implementation of a generic method for estimating the RMS error in depth data provided by any device, capable of generating data of type RGB-D, that is, an image and a depth map Same time. To verify the method was built an embedded system based on the NVIDIA Jetson TK1 and three sensors, the two versions of MS Kinect and the ZED stereo camera. At the moment of the data collection, the mathematical models of the RMS error were established for each device and, at the end, an analysis was made of the accuracy of each one.
