Abstract: Map fusion method, device and storage medium are provided, the method includes: determining, based on search guidance information, a search area of a first map from currently displayed at least two maps, the first map including first sample points; determining a second map from the at least two maps excluding the first map and determining, in the second map, a corresponding area of the search area, the second map including second sample points; determining target points, from the second sample points of the corresponding area, having matched attribute information with the first sample points in the search area, thereby to obtain sample point matching pairs, the sample point matching pair including the target point and the first sample point matched with the target point; fusing, based on the sample point matching pairs, the first map and the second map to obtain a target fusion map.

Abstract: A data processing method, a user equipment and an augmented reality system are provided. The method includes: displaying at least one virtual object in a display area of a first display screen; and triggering the at least one virtual object to move towards a second user equipment, such that when the at least one virtual object moves into an observation region corresponding to the second user equipment, the second user equipment displays the at least one virtual object in a display area of a second display screen. A user wearing a first user equipment including the first display screen can send the at least virtual object to a field of view of a user wearing the second user equipment, such that the at least virtual object can be seen by the user wearing the second user equipment. Therefore, interaction between the users wearing the respective user equipment can be improved.

Abstract: Method for processing frame loss of an ultrasonic wave, mobile terminal and storage medium are provided. The method is applied to the mobile terminal. The mobile terminal includes an ultrasonic receiving module and an ultrasonic proximity-calculating module. In the method, the ultrasonic receiving module receives ultrasonic data of the ultrasonic wave, and transmits the ultrasonic data to the ultrasonic proximity-calculating module. In addition, a load rate of the mobile terminal is acquired, and a frame loss rate of the ultrasonic data in the transmission process of transmitting the ultrasonic data from the ultrasonic receiving module to the ultrasonic proximity-calculating module is acquired. A parameter adjustment mode is determined based on the load rate and the frame loss rate, and system efficiency of the mobile terminal is adjusted based on the determined parameter adjustment mode, to cause the frame loss rate to be less than a target frame loss rate.
