Electromagnetic situation display technology of augmented reality electronic sandtable based on image recognition and tracking
The electromagnetic situation is complex and changeable,and the electromagnetic dimension in-formation is invisible.The traditional two-dimensional situation can not directly display the distribution of multidi-mensional electromagnetic data in the battlefield space,which is not conducive to the deployment of command and decision.The electromagnetic situation display technology of augmented reality electronic sandtable based on image recognition and tracking is studied.Through the local feature extraction algorithm,the position of the aug-mented reality digital content is located.Continuous 6-DOF tracking is carried out through the tight coupling opti-mization strategy of visual information and inertial measurement unit,so as to accurately realize the 3D modeling display of augmented reality electromagnetic situation information under the condition of super-large terrain.It is validated that the augmented reality electronic sandtable electromagnetic situation display technology realizes the layered and multi-dimensional display of panoramic augmented reality electromagnetic situation under the terrain scale of 400 km×400 km,supports multiple commanders to observe the battlefield situation from the global com-bat perspective at the same time,and provides commanders with a panoramic,novel and immersive combat expe-rience.
