Problems solved by technology

Although motion video analysis software can realize video clip interception, video comparison, slow motion playback, angle, displacement, and speed measurement, it still requires manual operation and cannot be completed automatically, and real-time analysis and feedback cannot be achieved on site
[0006] The third is to record video in real time through multiple cameras, and transmit it to the display terminal for real-time network display. This method can support playback and slow playback on the display terminal, but this solution cannot automatically capture key video clips

Embodiment 1

[0047] Such as Figure 1~2 As shown, the present invention provides a kind of real-time action video intelligent capture and feedback method, and described method comprises the steps

[0048]S1: Custom capture conditions;

[0049] S2: Capture and save the video clips meeting the capture conditions;

[0050] S3: analyze the saved video, and extract motion quantization parameters.

[0051] Specifically, the real-time action video intelligent capture and feedback method firstly sets the capture conditions by self-definition, and then when the recorded video meets the capture conditions, automatically captures and saves the video clips that meet the capture conditions, and then analyzes the saved video to extract Motion quantization parameters, such as speed, displacement, angle, motion trajectory, etc., to achieve the purpose of convenient and quick real-time capture, processing and feedback of the captured action video.

[0052] Further, the real-time action video intelligent...

Embodiment 2

[0055] In order to further realize the purpose of the real-time motion video intelligent capture and feedback method to capture, process and feed back the captured motion video conveniently and quickly, on the basis of Embodiment 1, the real-time motion video intelligent capture and feedback method For further optimization, specifically:

[0056] Step S1 in the real-time action video intelligent capture and feedback method includes the steps

[0057] S11: Adjust the direction of the main camera and the size of the video screen to make the human body movements in the video screen clear and proportionate;

[0058] S12: Select a video frame with a clean background as the capture setting image;

[0059] S13: Set the size of the video buffer to ensure that the video time that can be cached is greater than or equal to the completion time of the entire key action;

[0060] S14: On the capture setting image, select the start displacement point and the end displacement point of the k...

Embodiment 3

[0069] In actual use, there are often other non-subjects moving in the sports venue. When the non-subject moves into the preset viewing angle trigger area, the capture condition will be triggered by mistake, resulting in the wrong video being captured. In order to avoid this situation, improve the accuracy of the real-time action video intelligent capture and feedback method, and further realize the purpose of the real-time action video intelligent capture and feedback method to capture, process and feedback the captured action video in real time conveniently and quickly , on the basis of embodiment 2, further optimize the real-time motion video intelligent capture and feedback method, specifically:

[0070] A camera with a main viewing angle is called a main camera, the main viewing angle is a viewing angle in a horizontal direction, and the main camera is configured to shoot a motion video in a horizontal direction. Further, the real-time action video intelligent capture and...
