The invention discloses a mobile terminal and a photographing method thereof. The mobile terminal comprises an image pick-up module, an image synthesis module and a display module, wherein the image pick-up module is used for continuously picking up images through a camera; the image synthesis module is used for selecting high-brightness pixels from a basic image and images picked up at present to generate a synthetic image; the display module is used for displaying the synthetic image in real time, wherein the image synthesis module takes the first image picked up as the basic image for primary image synthesis and the generated synthetic image as the basic image for next image synthesis. In this way, the image synthesis technology is adopted to simulate long-time exposure, and a star trajectory photographing function is added to the mobile terminal so that a user can take a picture of a star motion trajectory by using the mobile terminal or the mobile terminal can be applied to similar application scenes; besides, the mobile terminal is further capable of realizing a preview image pick-up effect, meeting the diversified requirements of users and enhancing the experience of the users.

The invention discloses a panoramic camera. The panoramic camera comprises a pedestal (1) and a camera body (2), wherein the camera body (2) is located on the pedestal (1); the pedestal (1) includes a pedestal bottom plate (11), a pedestal upper cover (16), an external power supply (12), a turntable (13), a rotary knob (14) and a bracket (15), wherein the external power supply (12), the turntable (13), the rotary knob (14) and the bracket (15) are located between the pedestal bottom plate (11) and the pedestal upper cover (16); a through hole into which the rotary knob (14) can be horizontally inserted, and a groove into which the bracket (15) is vertically inserted are formed in the turntable (13); the rotary knob (14) is inserted into the through hole, so that the bracket (15) is rotatably fixed on the rotary knob (14) via the groove; and a top end of the bracket (15) is protruded out of the pedestal upper cover (16), and is rotatably connected with the camera body (2). According to the panoramic camera provided by the invention, after the installation is completed, the angle can be adjusted freely; and the photographed image can be spliced.

The invention discloses a method, device and plug-in for target tracking and semantic segmentation of sports video. The method includes: extracting a feature map according to input video frames and target initialization position information to obtain feature map information; Perform positioning to obtain target location information; fuse feature map information and target location information, and filter the background information of non-target areas; perform decoding operations according to fused features and feature map information, and finally form a semantic mask of the target. membrane. The device includes: a backbone network encoder, a prediction network unit, a feature fusion network unit and a decoder. The plug-in includes: video information component, video preview component, video playback component, new target component, tracking adjustment component and special effect component. Through the present invention, the tracking accuracy can be improved in sports videos with problems such as target deformation, rotation, and occlusion.
