| titleOfInvention | MICROMECHANICAL GYROSCOPE DRIFT CORRECTION SYSTEM USED IN THE AUGMENTED REALITY SYSTEM ON A MOVING OBJECT |
| abstract | The utility model relates to the field of navigation instrumentation. To increase the spatial orientation of operators controlling mobile objects (cars, watercraft and aircraft), augmented reality complexes in the form of head-mounted modules can be used, including, but not limited to, cameras and autonomous orientation subsystems that provide the determination of three angular coordinates of the position of the observation line in space . A drawback of orientation subsystems made on micromechanical elements (gyroscopes, accelerometers, magnetometers) is a significant data drift, especially in the yaw angle, reaching several hundred degrees per hour. The technical result of the proposed utility model is to increase the accuracy of spatial orientation by means of micromechanical gyroscopes by correcting their drift using data from a satellite navigation system and optical recognition of augmented reality markers. The technical result is achieved by the fact that, according to the on-board receiver of the satellite navigation system, a three-dimensional vector of the object’s movement is constructed using the regression analysis method and, when a section of rectilinear motion is detected, the gyro readings are corrected at the yaw and pitch angles by bringing them to the angular coordinates of the current motion vector. To take into account the position of the operator’s head relative to a moving object, optical recognition of graphic markers (clear images of various geometric shapes) that are motionlessly placed on the object in the field of view of the video camera included in the head unit of the augmented reality system is used. |
