DEVICE AND METHOD FOR CONTROLLING A ELECTRIC DEVICE USING A INERTIAL SENSOR AND A CAMERA

摘要

An apparatus and a method for controlling an electronic device by using an inertial sensor and a camera are provided to filter motion information, measured by the inertial sensor, through motion information obtained by analysis of an image photographed by the camera, thereby achieving more accurate control even for slow motion. An image analyzing unit(12) extracts feature points of an image inputted from a camera(11), and calculates the amount of upper and lower rotation, the amount of left and right rotation and the amount of back and forth motion of the feature points. A filtering unit(14) removes or outputs motion data measured by an inertial sensor(13) according to the left and right rotation amount and back and forth motion amount extracted by the image analyzing unit. A motion data operating unit(15) operates motion data of 4 degrees of freedom by using 2 axial motion data of the inertial sensor transmitted through the filtering unit, the left and right rotation amount calculated by the image analyzing unit and the back and forth motion amount calculated by the image analyzing unit. A control unit(16) generates control information by using the motion data calculated by the motion data operating unit, and perform a control operation.
