Title
(EN) Auxiliary positioning method and system based on positioning model
(ZH) 一种基于摆位模型的辅助摆位方法及系统
Abstract
(EN) The embodiment of the invention discloses an auxiliary positioning method and system based on a positioning model. The method comprises the following steps: determining a standard positioning model based on the posture data, collected by preset shooting equipment, of a target object and a scanning plan, corresponding to the target object, of imaging equipment; rendering the standard positioning model based on rendering parameters to obtain a target standard positioning model; fusing the target standard positioning model with a video which is currently acquired by the preset shooting equipmentand comprises a target object, and determining a positioning result; and displaying the positioning result to enable the target object to be positioned based on the positioning result. According to the method disclosed by the embodiment of the invention, the target standard positioning model is fused with the video of the target object to assist a patient or a technician in positioning based on the correct positioning result, so that the positioning efficiency is improved, and the risk of re-shooting caused by poor images is reduced.
(ZH) 本说明书实施例公开了一种基于摆位模型的辅助摆位方法及系统,所述方法包括:基于预设拍摄设备采集的目标对象的体态数据和成像设备对应于所述目标对象的扫描计划,确定标准摆位模型;基于渲染参数对所述标准摆位模型进行渲染,得到目标标准摆位模型;将所述目标标准摆位模型与所述预设拍摄设备当前采集的包括目标对象的视频进行融合,确定摆位结果;展示所述摆位结果,以使所述目标对象基于所述摆位结果进行摆位。本实施例公开的方法,通过目标标准摆位模型与目标对象的视频进行融合,辅助患者或技师基于正确的摆位结果进行摆位,提高了摆位效率,降低了因影像不佳导致的重新拍摄的风险。
