Embodiment approach

[0040] Such as figure 1 As shown, it is a preferred embodiment of a moving object motion reconstruction method of the present invention, including the following steps:

[0041] Step 10, before reconstructing the moving object, the contour extraction of the moving object should be realized firstly. The operation of extracting the outline of moving objects follows the attached figure 2 The operation flow chart of the method for extracting the contour of the moving object is shown in sequence.

[0042] Step 11, extract video frames from the video where the moving object is located, perform inter-frame global motion estimation on each frame in the video, and obtain global motion parameters between each frame. Global motion refers to the motion of pixels that account for a relatively large proportion in video sequence frames, and is mostly caused by camera motion in motion video. Global motion estimation refers to estimating the law of global motion between images based on two ...

Abstract

The invention discloses a sport object reconstituting method based on three-dimensional database used to achieve the sport reconstituting of the two-way sport object to obtain a three-dimensional sport object which comprises the following steps: extracting the sport object frame in the sport video to obtain the two-way frame information of the sport object, doing scale operation to the sport video to obtain the projecting array, using the projecting array and the virtual object model to establish two-way sport object frame from the three-dimensional database, looking for the reference sport data, using the video data as constraint condition to do deformation to the reference sport data to obtain the corresponding reconstituting three-dimensional sport sequence, doing smooth connection to the three-dimensional data of each reconstituting rim to obtain the continues three-dimensional sport.

Description

technical field [0001] The invention relates to a motion reconstruction method of a moving object, in particular to a motion reconstruction method of a moving object based on a three-dimensional database. Background technique [0002] Three-dimensional motion analysis is a hot issue in the computer field, and the research on human three-dimensional motion analysis is the most extensive. The three-dimensional motion analysis of the human body has a wide range of applications, for example, it plays an important role in the scientific training of competitive sports (especially skill sports). The key and foundation of 3D motion analysis is the acquisition of 3D motion information. At present, motion capture equipment is widely used to obtain three-dimensional motion information. This equipment can obtain more accurate three-dimensional motion data, but it is expensive, and there are many limitations in data collection (markers made of special materials are attached to moving ob...
