The invention discloses a
pediatric nursing practice teaching VR model generation method and
system based on a training video, and relates to the technical field of
artificial intelligence and
virtual reality, and the method comprises the steps: collecting a
pediatric nursing operation video for preprocessing, extracting a key motion frame, separating
medical staff, a child patient and a medical tool, converting the key motion frame into an editable 3D model, and carrying out the recognition of the editable 3D model; acquiring multi-
modal data corresponding to the
pediatric nursing operation, matching the converted 3D actions with
semantics through a multi-
modal large model, and optimizing 3D conversion; key contact points are marked in the 3D action sequence to carry out
collision detection point burying, an operation process is defined to generate a 3D
animation sequence with interaction logic to construct a VR teaching scene, the reasonability of the operation logic is verified through
user testing, and scene correction is carried out. Through video analysis, 3D element replacement and
animation point burying technologies, intelligent generation of pediatric
nursing VR teaching resources is realized, and a more efficient and more immersive solution is provided for
nursing education.
