Diseño de un prototipo de control de acceso del personal mediante reconocimiento facial en 3D para empresas públicas o privadas.

Abstract

A design of a prototype of personnel access control was performed using 3D facial recognition software for public or private companies, which it was temporarily implemented in Cementera de Chimborazo Public Company EP (EPCEEP) which is located at 14.7 km from the city of Riobamba, to decrease the access time at entry and exit of the workplace. In the process of implementation of the prototype the logical deductive method was used, A person has an average time of 1 second to check in, causing a bottleneck at the entrance. With the implemented system is achieved that the staff do not stop at the time of admission, eliminating crowds in the registration place. For the execution a Genius camera HD Webcam 1.3 Megapixel facecam 1000x Microphone, a Core i7 computer, a LabVIEW 2014 programming platform of the National Instruments and the OpenCV Wrapper for LabView library were used. The ratio of time in each process indicates that the uptake is 30 frames per second; the image processing is 10 times per second and the passage of people through the detection area is, 0.66 people per second, giving optimum results. The system has conditions of use for proper operation like; the user should not be using a scarf, cap, or any device that covers the face, users as possible should go with their heads high through the control area, the users shouldn't walk on a single line so they don't cover the face of the following person and don't run through the detection area. In field tests conducted with front lighting, efficient results with acceptance levels were obtained. It is concluded that the system has an acceptance rate of 90% and 10% error by the tabulated test data and statistical formulas. lt is recommended that for correct operation of the system to take into account the conditions described above, and a trained person in lighting and computer skills.
