Abstract
(EN)
An apparatus for target location is disclosed. The apparatus includes a housing, which includes a range sensor to generate range data, an image sensor to generate image data, an inertial sensor to generate inertia data, and a processor. The processor is configured to receive the image data from the image sensor and determine a first orientation of the housing and receive the inertia data from the inertial sensor and modify the first orientation based on the inertia data to produce a modified orientation of the housing.

L'invention concerne un appareil de localisation de cible. L'appareil comprend un boîtier, qui comprend un capteur de distance pour générer des données de distance, un capteur d'image pour générer des données d'image, un capteur inertiel pour générer des données d'inertie, et un processeur. Le processeur est configuré pour recevoir les données d'image provenant du capteur d'image et déterminer une première orientation du boîtier, et recevoir les données d'inertie provenant du capteur d'inertie et modifier la première orientation sur la base des données d'inertie pour produire une orientation modifiée du boîtier.
