Embodiment Construction

[0051] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0052] figure 1 It is a block diagram of the device for estimating the wound area provided by the embodiment of the present invention, such as figure 1 As shown, the device includes:

[0053] The image recognition module is configured to perform image recognition on the captured image, and identify a two-dimensional scale image from the captured image. Specifically, first, binarize the captured image to obtain white connected domains, and calculate the number of pixels in each white connected domain; secondly, for each white connected domain, construct a The simulation scale area with the same shape as the two-dimensional scale graph; then calculate the...

Abstract

The invention discloses a method and device for estimating wound area and relates to the field of medical equipment. The device comprises an image recognition module used for recognizing a 2D scale image from a captured image; a scale determining module for determining a proportion of the image to an actual dimension by using the recognized 2D scale image; an image clustering module for clustering the captured image according to colors to obtain multiple types of wound images corresponding to different types of tissue components; and an area computing module for estimating the wound area of different tissue components by using the proportion of the image to the actual dimension and the multiple types of wound images corresponding to the different types of tissue components. The method and device may automatically, rapidly, and accurately provide the area information of the whole wound and the area information of different components of the wound, are easy to operate and high in computational precision.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method and device for estimating the wound area. Background technique [0002] Clinically, in order to evaluate the healing of chronic wounds, the index of wound area is used as an important data for evaluating wounds. The current area measurement schemes include ruler measurement, graph paper measurement, manual measurement by taking photos, and automatic measurement. [0003] The ruler measurement method uses a ruler to measure the long and short diameters of the wound, and then performs multiplication to measure the wound area. This scheme needs to touch the wound, and the error is very large. [0004] The graph paper measurement method uses transparent graph paper to determine the wound area by counting the number of squares the wound contains. This scheme needs to touch the wound, and the error is relatively large. [0005] Take photos of the wound by taking pictures a...
