ABSTRACT
In this paper, a fast face marker detector for head radiotherapy patient posing is investigated. The 3D coordinate data of feature points of head radiotherapy patients' faces are collected by an RGB-D camera, and the 3D coordinate data of feature points of head radiotherapy patients' faces are extracted for fast face marking using a face feature point matching algorithm with a lightweight backbone network model. By comparing the marked patient head feature point data with the real-time data of the head of radiotherapy patients, the comparison error is used as the basis for the pose operation. The results show that the detector can achieve the desired positional effect. Therefore, this detector can meet the clinical demand for a short time and high precision posing system for precise radiotherapy.
