Abstract

En el presente documento se proporcionan sistemas y/o dispositivos para implementar un dispositivo de rastreo para rastrear una posición/ubicación y la orientación de un objeto. El dispositivo comprende uno o más lados que definen una forma predeterminada y una pluralidad de unidades de medición inercial (IMU, por sus siglas en inglés) montadas en uno o más lados de la forma predeterminada. Cada IMU se configura para detectar el movimiento del objeto y generar datos de salida inercial que representan una posición y/u orientación del objeto. Cada IMU incluye un primer subsensor y un segundo subsensor. Cada IMU se coloca a una distancia y orientación predeterminadas en relación con un punto central del dispositivo de rastreo. El dispositivo también comprende un controlador acoplado de una forma comunicativa con la pluralidad de IMU, en donde el controlador se configura para recibir los datos de salida a partir de cada una de la pluralidad de IMU, y para determinar la posición/ubicación y orientación del objeto con base en los datos de salida recibidos a partir de la pluralidad de IMU y los puntos de datos conocidos para la forma predeterminada con el fin de eliminar la deriva desde los datos del sensor.
