摘要：
A system for analyzing wound states includes an image capture device and an image analysis device. The image capture device is configured to obtain a plurality of infrared (IR) images of a part of user body including a wound at different time points, wherein the IR images includes a first IR image captured at a first time point and a second IR image captured at a second time point, the first IR image includes a first vessel pattern of the part of the user body, and second IR image includes a second vessel pattern of the part of the user body. The image analysis device couples to the image capture device and includes a wound detection module, an image information calibration module and a wound analysis module. The wound detection module is configured to detect a first wound region and a second wound region corresponding to the wound from the first IR image and the second IR image, respectively. The image information calibration module is configured to obtain a first group of features by identifying features outside the first wound pattern in the first IR image, obtain a second group of features by identifying features outside the second wound pattern in the second IR image, generate calibration information according to the first and second groups of features, and align the second IR image with the first IR image by using the calibration information, so as to generated a calibrated image. The wound analysis module is configured to obtain information of wound changing states by comparing a third wound region corresponding to the wound identified from the calibrated image with the first wound region.一種傷口狀態分析系統,包括影像取得裝置以及影像分析裝置。影像取得裝置用以取得多張在不同時間點對使用者身上包括欲觀察傷口的一身體部位所擷取之紅外光影像,該些紅外光影像包括在第一時間被擷取之第一紅外光影像以及在第二時間被擷取之第二紅外光影像,該第一紅外光影像包括該身體部位的第一血管圖樣,該第二紅外光影像包括該身體部位的第二血管圖樣。影像分析裝置耦接該影像取得裝置,並包括傷口偵測模組、影像資訊校準模組以及傷口分析模組。傷口偵測模組用以自該第一紅外光影像偵測對應欲觀察傷口的第一傷口區域,並自該第二紅外光影像偵測對應欲觀察傷口的第二傷口區域。影像資訊校準模組用以辨識該第一紅外光影像中該第一傷口區域以外區域之特徵點以取得第一特徵組,辨識該第二紅外光影像中該第二傷口區域以外區域之特徵點以取得第二特徵組,依據該第一特徵組和該第二特徵組產生校準資訊,並利用該校準
