[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-3 The figure shows a highly integrated portable mobile camera terminal. In view of the problem that the existing training recording and broadcasting equipment is generally large in size and cannot realize convenient shooting, a highly integrated portable mobile camera terminal is designed. The optical lens, CMOS sensor and ARM main control chip are integrated in a portable mobile camera terminal, so that one terminal can complete the video processing and transmission functions. The portable mobile terminal designed in this application can be rotated and fixed to the recording and broadcasting vehicle at multiple angles through an external rotating base. It not only has the function of portability, but also can be fixed to the recording and broadcasting vehicle at any time to realize a more complete recording and broadcasting function. The structure of this application is further explained in principle in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, the present application provides a highly integrated portable mobile filming terminal structure, including a housing 1, a lens frame 2, an optical lens 3, a handheld portion 4, a fixing portion 5 and a director panel 6. The lens frame 2 is fixedly connected to the housing 1, the optical lens 3 is fixed inside the lens frame 2, a raised handheld portion 4 is provided on the outside of one side of the housing 1, and the handheld portion 4 is integrally formed with the housing 1. The housing 1 and the handheld portion 4 are connected to each other in a hollow space for placing a main control module. A handheld groove is provided at the connection between the housing 1 and the upper end of the handheld portion 4 for easy holding.

[0021] like Figure 2 As shown, the rear of the housing 1 is connected to the rotating base 7, and the rotating base 7 can be rotated to achieve relative rotation with the housing 1. The director panel 6 is fixedly connected to the side of the rotating base 7. In the present application, the director panel 6 and the housing 1 adopt a separate structure, and the two achieve relative rotation through the rotating base 7. When actually shooting, the user rotates the rotating base 7 to not only adjust the shooting angle, but also adjust the relative angle of the director panel 6. The user can adjust the director panel 6 to the best position when shooting targets at different angles.

[0022] The highly integrated portable mobile recording terminal provided by this application can not only realize the portable shooting function, but also can be easily installed on the existing training recording and broadcasting vehicle. Figure 3 As shown, a fixing part 5 is provided at the other end of the rotating base 7, and the training recording and broadcasting vehicle is detachably fixed to the fixing part 5. In this embodiment, the fixing part 5 is fixed to the recording and broadcasting vehicle by a magnetic suction fixing method, and the fixing part 5 and the universal arm of the training recording and broadcasting vehicle are respectively provided with mutually fitting magnetic fixing parts at corresponding positions. In actual use, a variety of fixing methods including chuck type and buckle type fixing methods can also be used.

[0023] The highly integrated portable mobile recording terminal designed in this application can not only be used in conjunction with the training recording and broadcasting vehicle structure or realize the mobile recording function independently in terms of appearance and structure, but also has a high degree of integration in module design, integrating the main control module into the recording terminal, so that the mobile recording terminal can realize rich recording and broadcasting functions while being compact in appearance and simple in structure. Figure 4 As shown, the optical lens 3 is connected to the CMOS sensor, and the CMOS is directly connected to the main control module. The main control module further integrates an image signal processing unit ISP and a neural network processing unit NPU for AI analysis on the basis of a conventional central processing unit CPU, a graphics processing unit GPU and a processing unit VPU for video encoding and decoding.

[0024] The optical lens 3 collects external image data, performs photoelectric conversion through the CMOS sensor, and then outputs it to the image signal processing unit ISP of the main control module. The ISP processes the image through the image processing algorithm and then directly transmits the image to the director panel 6.

[0025] After ISP processes the image signal transmitted by CMOS, it encodes the YUV image into data in H264 or H265 format through the VPU module in the main control module, and finally provides it to a third party through the network interface through standard protocols such as RTSP, RTMP, ONVIF, etc., to realize functions such as remote live broadcast.

[0026] After the ISP processes the image signal transmitted by the CMOS, the NPU can also perform AI enhancement processing according to actual needs. AI enhancement processing includes but is not limited to image enhancement, text enhancement display, etc.

[0027] The portable mobile terminal designed in the present application adopts a more flexible design in structure, which realizes the function of being detachable at any time and portable camera. Through the rotatable base structure, the director panel is separated from the shell, which can adjust the shooting angle more flexibly than the traditional camera terminal structure, thereby improving the user experience. In addition, the present application can also be used in conjunction with the traditional training recording and broadcasting vehicle. It can be fixed in the corresponding position of the recording and broadcasting vehicle to replace the surgical field camera of the recording and broadcasting vehicle for shooting, thereby achieving the effect of multi-functional photography. The present application also integrates a main control module inside the shell. On the basis of the conventional central processing unit CPU, graphics processing unit GPU and processing unit VPU for video encoding and decoding, it further integrates the image signal processing unit ISP and the neural network processing unit NPU for AI analysis, so as to realize the analysis, processing and presentation of image data on the terminal side, and meet downstream applications such as live streaming.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
