Abstract

The invention provides a method and device for calculating the area of a damaged body surface area. The method and device for calculating the area of the damaged body surface area can achieve high precision on the part, with a large curvature, of the human body and also solve error problems caused by shooting angles. The method comprises the steps of obtaining images of the damaged body surface part at multiple angles; extracting features of the images, conducting feature matching on every two images, and reconstructing a three-dimensional model of the damaged body surface part according to amatching result; conducting UV expansion on the three-dimensional model to obtain a two-dimensional image of the damaged body surface part; obtaining the damaged body surface area in the two-dimensional image according to an image segmentation algorithm, and obtaining the area of the damaged body surface area according to a proportional scale conversion algorithm.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and a device for calculating the area of ​​a body surface injury area. Background technique [0002] Calculation of body surface injury area is an important task in clinical medicine research and forensic identification. In clinical medical research and forensic identification, the accuracy of the area value of body surface damage directly affects the doctor's diagnosis and treatment plan and research, and even determines the conclusion of judicial judgment. In forensic forensic identification, body surface injuries such as trauma, contusion, and burns are the most common types of injuries, and the area of ​​the body surface injury area determines the judgment of the level of disability. [0003] The 2D computer software system based on damage image is the most commonly used non-manual calculation method at present. It uses the photos of the damaged image to obtain t...
