A data-driven nearshore swell animation synthesis method and system

Abstract

The invention provides a data driving inshore surge animation synthesis method and a system and belongs to the image processing and computer vision field. The method comprises steps that a monocular video of water surface videos is reconstructed, the height field data of the monocular video is acquired, opening operation reconstruction and closing operation reconstruction for the water surface videos are carried out, surge masks are acquired, the surge masks are processed through a morphological refinement algorithm, and the surge framework information is acquired; according to the surge masks and the surge framework information, a rapid surge height change model is constructed, and a frame sequence graph is acquired according to the rapid surge height change model and the height field data; a target shape of surge inputted by a user is acquired, an initial shape of the surge in the frame sequence graph is changed into the target shape, and the target shape generates animation. Through the method, reusability of the reconstruction data is improved, and the surge information and the control mode are made to be more simple and visual.

Description

technical field [0001] The invention relates to the fields of image processing and computer vision, in particular to a method and system for synthesizing nearshore swell animations driven by data. Background technique [0002] The simulation of natural phenomena has always been one of the hot issues in computer graphics research. Among them, fluid simulation, especially the rapid modeling and controllable animation technology of large-area water surfaces and waves, is widely used in film and television special effects, advertising, 3D game development, virtual reality, etc. Various fields have been more and more widely used and have important application value. However, natural waves are a very complex physical phenomenon. Influenced by various factors, most of the waves are uneven in height and length. Sometimes they appear as relatively periodic water waves, and sometimes there are broken waves with drastic changes in shape, curling and splitting, and splashing water. Str...

Problems solved by technology

[0008] Among the above common methods, the traditional physics-based method requires a large amount of calculation, takes a long time, and is more sensitive to parameter settings. There are certain technical difficulties in the detailed simulation of complex features.

Most of the existing data-driven water surface reconstruction methods require complex data acquisition device design, and have certain requirements for water bodies or require pretreatment, using structured light and predetermined patterns as marks, etc. These requirements can be achieved under indoor conditions. Satisfied, but difficult to implement outdoors
