| Abstract (English): | Currently, the most common methods for proper capture of human movement in three dimensions require a laboratory environment and setting markers, accessories or sensors to the body segments. However, the high cost of this equipment is a limiting factor in diverse environments. Motion capture systems such as Microsoft Kinectpresent an alternative approach to motion capture technology. In this paper, two motion capture systems are compared by means of joint trajectories and anthropometric measurements of a person in a normal gait cycle. The first is accurate trading system that uses markers (Vicon), and the second is Microsoft Kinect camera. Both systems were evaluated in order to compare the geometric difference and the RMS error between the joint human walking paths obtained for each of the systems. The results show a greater variance in anthropometric measures and joint trajectories for Kinect, although this system is inexpensive and easy to use and install, cannot be used for precise kinematic analysis of human walking.

Sin embargo, el alto costo de estos equipos es un factor limitante en diversos entornos de trabajo. Sistemas de captura de movimiento como Microsoft Kinect presentan un enfoque alternativo a la tecnología de captura de movimiento. En este trabajo se comparan dos sistemas de captura de movimiento por medio de las trayectorias articulares y las medidas antropométricas de una persona en un ciclo de marcha normal. El primero de ellos, es un sistema comercial de precisión que utiliza marcadores (Vicon ) y el segundo, es la cámara Microsoft Kinect. Ambos sistemas se evaluaron con el propósito de comparar la diferencia geométrica y el error RMS entre las trayectorias articulares de la marcha humana obtenidas por cada uno de los sistemas. Los resultados muestran una varianza mayor en las medidas antropométricas y trayectorias articulares para el Kinect, aunque este sistema es de bajo costo y de fácil uso e instalación, no puede ser utilizado para un análisis preciso de la cinemática de la marcha humana.
