The invention provides a
senile dementia clock drawing experiment automatic evaluation method and
system based on non-rigid registration, and belongs to the technical field of
artificial intelligence, and the method comprises the steps: S1, obtaining
clock drawing experiment data of a testee, and carrying out the preprocessing of the obtained
clock drawing experiment data, and obtaining a first
point cloud image; s2, performing non-rigid registration on the first
point cloud image and a preset standard template to obtain a second
point cloud image after non-rigid registration; s3, performing clock drawing experiment analysis on the second point cloud image to obtain an analysis result; and S4, scoring the analysis result according to a preset scoring standard to obtain a total
score of the
senile dementia scale of the testee. The non-rigid registration method based on
machine vision has the advantages that automatic and intelligent evaluation of the
senile dementia scale clock drawing experiment is achieved, evaluation efficiency and accuracy are improved, a more effective auxiliary means is provided for diagnosis and treatment of senile
dementia patients, and the non-rigid registration method based on
machine vision has wide application prospects.
