Security alarm method, terminal and computer readable storage medium

The invention provides a security alarm method, a terminal and a computer readable storage medium, and belongs to the technical field of image recognition. In order to solve the problem of false alarm in application scenes such as drowning prevention alarm in the prior art, the method comprises the following steps of: acquiring an image, extracting a region of interest contained in the image, performing image semantic segmentation on the region of interest through an image recognition model based on image semantic segmentation to obtain a target region contained in the region of interest; and when the region of interest is determined to contain the portrait and the portrait is determined to be close to the target region, a safety alarm is given out, so that the collected image is segmented by adopting an image semantic segmentation technology to automatically identify the water area and the portrait in any shape, and in application scenarios such as drowning prevention and expelling alarm, the safety of the w
