Abstract
A method for simulating a figure gait contour in a three dimensional model relates to the technical field of three dimensional simulation. The steps are as follows: data in the three dimensional model is collected and the data is analyzed; a plurality of coordinates in the three dimensional model is set and data obtained through different coordinates are subjected to contrast and analysis; one coordinate is selected as a present simulation coordinate, and a figure visible area, of which a radius is R, is displayed through usage of the a three dimensional graph; a mobile center coordinate of figure movements is determined according to user inputs; a program is set to enable the figure to move according to assigned coordinates; on the basis that an original model energy item is saved, a gradient value for separating a front graph and a rear graph is added; and an accurate value of the gait contour is calculated through a new function. The gait contour of the figure in the three dimensional model can be rapidly and highly efficiently simulated. An important practical significance is provided for development of the three dimensional system.
Description
Technical field:
The present invention relates to three-dimensional simulation technical field, be specifically related to a kind of method simulating personage's gait profile in three-dimensional model.
Background technology:
Three-dimensional model is the For Polygons Representation of object, and logical conventional computer or other video equipment show.The object of display can be the entity of real world, also can be imaginary object.The thing that any physics nature exists can represent with three-dimensional model.Now, three-dimensional model is for various different field.Them are used to make the accurate model of organ in medical industry; They are used for movable personage, object and real film by film industry; Video game business using them as the resource in computing machine and video-game; In scientific domain using they accurate models as compound; They are used for showing that the buildings of proposal or landscape show by building industry; They are used for designing new equipment, the vehicles, structure and other application by engineering circles; In nearest decades, field of earth sciences starts to build three-dimensional geological model.
Gait feature identification is different from other biometrics identification technology (as face, iris, fingerprint etc.), gait be people external, show dynamically, and maintain close ties with space-time, simultaneously, compared with other biological identification technology based on static nature, Gait Recognition has the significant advantage such as untouchable, Noninvasive and difficult hiding, and these advantages make it have very large using value in field of intelligent monitoring.
Current computer speed and memory capacity are in continuous improve, picture pick-up device is mounted in a lot of region to be used, along with the awakening day by day that increasingly serious, the social safety of world-wide safety situation are realized, the research of Gait Recognition will permeate the every field of people's daily life, and this remote identification can with any one static state closely identity recognizing technology merge mutually.
Summary of the invention:
The object of this invention is to provide a kind of method simulating personage's gait profile in three-dimensional model, it can simulate the gait profile of personage in three-dimensional model fast and efficiently, improve sharpness and the distinguishability of gait profile, the exploitation for three dimension system has important practice significance.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its step is as follows: 1, collect the data in three-dimensional model and by data analysis, deposited by Data classification after analysis;
2, set the coordinate in several three-dimensional model, then the data obtained by different coordinate carry out contrasting, analyzing;
3, a selected coordinate is present day analog coordinate, the region that the personage that use three-dimensional plot engine display radius is R is visual;
4, determine the coordinate of the Mobility Center of personage's movement according to user's input, setting program makes personage move according to specified coordinate;
5, on the basis retaining original model energy item, add the Grad of image before and after segmentation, new pattern function can be obtained;
6, the exact value of gait profile is calculated by new function.
This embodiment has following beneficial effect: it can simulate the gait profile of personage in three-dimensional model fast and efficiently, and improve sharpness and the distinguishability of gait profile, the exploitation for three dimension system has important practice significance.
Embodiment:
This embodiment is by the following technical solutions: its step is as follows: Data classification also by data analysis, is deposited after analysis by the data of 1, collecting in three-dimensional model;
2, set the coordinate in several three-dimensional model, then the data obtained by different coordinate carry out contrasting, analyzing;
3, a selected coordinate is present day analog coordinate, the region that the personage that use three-dimensional plot engine display radius is R is visual;
4, determine the coordinate of the Mobility Center of personage's movement according to user's input, setting program makes personage move according to specified coordinate;
5, on the basis retaining original model energy item, add the Grad of image before and after segmentation, new pattern function can be obtained;
6, the exact value of gait profile is calculated by new function.
This embodiment has following beneficial effect: it can simulate the gait profile of personage in three-dimensional model fast and efficiently, and improve sharpness and the distinguishability of gait profile, the exploitation for three dimension system has important practice significance.
