Description

Technical Field

[0001] The present invention relates to the technical field of video post-production, and in particular to a video post-production method and system based on video technology. Background Art

[0002] In this era of booming digital media, video production technology has been at the forefront of continuous innovation. Video post-production methods that apply virtual video technology are a key link in video creation, aiming to provide a more engaging and lifelike visual experience. However, despite our significant technological progress, traditional video post-production methods still face a series of challenges in some important aspects.

[0003] First, the accuracy and realism of traditional methods have obvious bottlenecks. As audiences' requirements for video quality increase day by day, the precise requirements for simulated cameras to operate in actual scenes have become more urgent. Traditional methods are difficult to fully restore factors such as lighting, shadows, and refraction in real scenes, resulting in insufficient accuracy and realism in the visual effects of the generated virtual videos. Secondly, traditional video post-production methods lack effective means to capture the internal and external parameters of the camera and environmental factors. There is a lack of effective means to accurately capture the internal and external parameters of the camera during operation, the influence of camera jitter and environmental factors. This limits the generation process of virtual videos and lacks sufficient controllability and stability.

[0004] The existing publication number is CN118488237A, which is a video post-production method and system that uses virtual video technology. In the S1 stage, it collects rich camera internal parameters, vibration data and environmental data, and obtains the camera parameter coefficient Csx through analysis and calculation in the S2 stage, which provides an accurate basis for subsequent virtual video production. This helps to eliminate camera parameter errors and improve the accuracy of video production. In the analysis and calculation of the S2 stage, the camera influence coefficient Yxx and the environmental shadow coefficient Hyx are obtained, and factors such as the external influence of the camera and ambient lighting are fully considered, which helps to optimize post-production more comprehensively. In the S4 stage, by using the first calibration, the second calibration results and the third calibration results to generate corresponding optimization strategies, the image data in the actual scene is projected by the camera, and a highly restored virtual video scene is generated, which improves the overall production efficiency and quality.

[0005] However, in actual preparation, the video production time and memory required are long, and conventional computer equipment cannot operate effectively and stably, which may lead to technical problems such as low efficiency in post-production. Summary of the invention
