目的：介绍一种无创创面参数评估装置，以克服传统方法粗糙、不准确、患者痛苦的缺点。该设备估计伤口的形态参数，并通过投影上次检查中获得的伤口边缘来提供关于伤口愈合状态的增强现实(AR)视觉反馈，从而改善医患沟通。方法：用立体摄影测量法建立精确的创面三维模型，并通过自组织映射进行精化。3D模型用于估计伤口愈合评估的物理参数，并基于微型投影仪集成AR功能。物理参数估计功能是根据精确度、准确度、操作员间的可变性和重复性来评估的，而AR缠绕边界投影是根据同一模体上的准确性来评估的。结果：线性参数的准确度和精密度分别为2%和1.2%，面积和体积的准确度和精密度分别为1.7%和1.3%。AR投影显示误差距离
Objective: This work presents a device for non-invasive wound parameters assessment, designed to overcome the drawbacks of traditional methods, which are mostly rough, inaccurate, and painful for the patient. The device estimates the morphological parameters of the wound and provides augmented reality (AR) visual feedback on the wound healing status by projecting the wound border acquired during the last examination, thus improving doctor-patient communication. Methods: An accurate 3D model of the wound is created by stereophotogrammetry and refined through self-organizing maps. The 3D model is used to estimate physical parameters for wound healing assessment and integrates AR functionalities based on a miniaturized projector. The physical parameter estimation functionalities are evaluated in terms of precision, accuracy, inter-operator variability, and repeatability, whereas AR wound border projection is evaluated in terms of accuracy on the same phantom. Results: The accuracy and precision of the device are respectively 2% and 1.2% for linear parameters, and 1.7% and 1.3% for area and volume. The AR projection shows an error distance
