Embodiment Construction
[0022]The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.
[0023]Such asfigure 1 withfigure 2 As shown, a video synthesis method includes the following steps,
[0024]S1: Decompose the video to be synthesized into sequential frame-by-frame images;
[0025]S2: Determine whether the current frame image is detected; if not, skip the detection of the current frame image, and copy the detection information obtained in the previous detection process to the current frame image; The frame image is detected to obtain the detection information, which is marked on the current frame image;
[0026]S3, judge whether the instant detection speed meets the real-time detection requirements; if not, gradually increase the detection interval, and return to S2 to execute the next frame of image; if yes, gradually redu...

The present invention relates to a video synthesis method, system and computer storage medium. The method includes: S1, decomposing the video to be synthesized into sequential frame-by-frame images; S2, judging whether the current frame image is detected; if not, making the current frame image Skip the detection, and copy the detection information obtained in the last image detection process to the current frame image; if so, detect the current frame image, obtain the detection information, and mark it on the current frame image; S3, judge the instant detection speed Whether it meets the real-time detection requirements; if not, gradually increase the detection interval, and return to S2; if so, gradually reduce the detection interval or maintain the current detection mode, and return to S2; S4, take the first frame image as the beginning of the video , and subsequently combine the current frame image with detection information and the previous frame image into a video according to the detection order. The invention performs self-adaptive frame-by-frame detection on video sequence images, and does not change the accuracy of the detection model while ensuring real-time detection.
Description
Technical field[0001]The invention relates to the field of video processing, in particular to a video synthesis method, system and computer storage medium.Background technique[0002]Infrared smart car auxiliary uses infrared camera equipment as imaging equipment, which can realize all-weather and all-time imaging and detection of specific targets. It is an important solution for visible light intelligent vehicle auxiliary driving system restricted by visible light imaging conditions. Infrared intelligent vehicle auxiliary driving system is intelligent The attention of researchers in the field of assisted driving and autonomous driving. Although the vehicle assisted driving system based on the intelligent detection algorithm has a high detection accuracy, because it extracts all the features of the target through a large number of convolution operations, the detection speed is relatively faster than the traditional method of extracting only the contour features of the target using ima...
