With the continuous development of the display industry,new display methods keep emerging,people's pursuit of vision has never stopped,holographic display is considered as an ideal display mode.Technically,we find that the phenomenon of negative refractive index can realize the media-free aerial imaging.With the maturity of the media-free aerial imaging technology,a stable and reliable interactive system is needed to identify the various operations of users in the air.The system can accurately identify the location information of the user's click in the air,and feedback the location information to the master control system.Through the simulation of HID device or mouse click,the user can complete a complete interaction with the real image in the air.The sensors used in the interactive system include Realsense SR300,Kinect DK and Airbar.Among them,Realsense SR300 provides the 3d coordinate data of 22 bone points of the user's hand.Through the corresponding interface,the information of the interaction points can be easily obtained.Kinect DK provides a depth map with a wide Angle of view,so that the scope of the interaction area becomes larger.By analyzing the depth map,we realize the gravity center climbing algorithm to obtain the information of the interaction points.Airbar is an infrared technology that realizes two-bit positioning with one-dimensional sensor.It has infrared transmitter and infrared receiver with specific Angle.We can configure the interaction area through ASN.1The system is based on RealSense SR300 hardware,developed using C++,and optimized on the latest Azure Kinect DK hardware.At the same time,the interactive mode based on the infrared module of Airbar is realized in the system.The interactive system has been used in media-free aerial imaging equipment such as hospital self-service machines and elevator cars,and received good expected results.
