Embodiment Construction
[0054] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
[0055] Since the existing method of manually correcting the mannequin’s piercing in each frame of image consumes a lot of labor, in order to reduce the labor consumption in the mannequin’s piercing correction, the embodiment of the present invention provides a mannequin piercing Visibility detection method, device and electronic equipment.
[0056] see figure 2 , figure 2 A process for the visibility detection method of human body model penetration, including:
[0057] Step 201, for each frame of 3D mesh, obtain the coordinate data of each vertex of each triangle of the human body model corresponding to the frame of 3D mesh; The vertices of are determined as piercing vertices.
[0058] In the embodiment of the present invention, the skin of the human body model is formed by splicing a plurality of...

The embodiment of the invention provides a human body model penetration visibility detection method and device and electronic equipment, and the method comprises the steps of obtaining the coordinate data of each vertex of each triangle of a human body model corresponding to a frame of penetration three-dimensional grid for each frame of three-dimensional grid; determining vertexes of all triangles of a human body model penetration area corresponding to the frame of three-dimensional grid as penetration vertexes; acquiring coordinate data of a camera; for each model-penetration vertex, determining a shielding relationship between the model-penetration vertex and each triangle of the human body model based on the coordinate data of the model-penetrating vertex, the coordinate data of the camera and the coordinate data of each vertex of each triangle of the human body model; and if all the model penetration vertexes in the human body model corresponding to the frame of three-dimensional grid are invisible at the visual angle of the camera, determining that the model penetration of the human body model corresponding to the frame of three-dimensional grid under the frame of action posture is invisible. By adopting the method, the labor consumption for correcting the human body model penetration is reduced.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method, device and electronic equipment for detecting the visibility of a human body model through a mold. Background technique [0002] At present, since 3D virtual characters are more and more widely used in animation production and movie special effects, the production of 3D virtual characters is also becoming more and more important. At present, the production of 3D virtual characters mainly includes: capturing various actions of the target character through motion capture technology, and then transferring the captured actions to a designated 3D human body model, and driving the 3D human body model to make various actions. However, there are many problems in the process of migrating the captured actions to the specified 3D human body model. For example, because the target figure is different from the 3D human body model that needs to be driven, it may cause the dri...
