extracting feature points in an original image pre-stored for the photographic subject corresponding to the selected at least two feature points on the basis of the calculated relative sizes; and
comparing the image of the photographed subject with the original image on the basis of the selected feature points and the extracted feature points;

9. The control method for cleaning the care box for the wound according to claim 5, characterized in that the control method for cleaning the care box for the wound further comprises a control method adopted by an electromagnet, and the control method comprises the following steps:
in an initial state, the electromagnet is in a power-off state or a reverse power-on state, the electromagnet extends out of and is kept by the telescopic body of the electromagnet, and the lock body is clamped by the telescopic body, or a clamping block connected with the telescopic body of the electromagnet extends out of and clamps the lock body, so that the lock body cannot be opened, and the electronic lock is in a locking state;
if the electronic lock obtains an unlocking instruction and needs to be automatically unlocked, the electromagnet is powered positively to enable the telescopic body to retract; the telescopic body/clamping block in the retraction state releases the clamping state of the lock body, so that the lock body is opened, and the electronic lock is automatically opened.
10. The control method for cleaning the nursing box for the wound according to claim 5, characterized in that the control method for cleaning the nursing box for the wound further comprises a brightness detection method adopted by the sensing module:
acquiring a first image of an environment to be detected through an image acquisition unit, and analyzing the first image by using a preset rule to obtain a first brightness detection value of the environment to be detected;
detecting a second brightness detection value of the environment to be detected through a brightness sensor, wherein the second brightness detection value and the first brightness detection value are ambient brightness in the opposite direction;
and presetting a brightness calculation model by using a logistic regression or training classifier, and calculating a result value representing the brightness level of the environment to be measured through the preset brightness calculation model based on the first brightness detection value and the second brightness detection value.
