The purpose of this project is the control of motion and direction in real time of a wheel chair using machine vision algorithms in a Linux box. The main goal of this project is the signal acquisition from video camera and collision sensors for post processing in the C++ algorithm in the Linux Box and later get the motor control in the traction mechanism of the wheel chair. The C++ algorithm have several task, first to obtain the real time image from webcam and later processing for identification of the direction of movement of the human face. Second to calculate the speed of movement for to generate the PWM output for motor movement, this information output using the RS232C driver to a microcontroller card attached to the motor control box in wheel chair mechanism. Finally, obtain the collision sensor status for security implementation; all them in real time. The main reason for development and implementation of this solution in linux is the use of open source software tools and get a more stable platform in the base system due to the characteristics of the end use of system. The end user of the system will be a cuadrapejic person without possibility of use of hand and foot, only his head. This system is a replace of joystick functions in the main control of the wheel chair.
