US12416472 - Human detection and warning method, sighting device and computer-readable storage medium

The patent describes a method for detecting human targets within the field of view of a sighting device, utilizing image recognition to determine if a human is being aimed at. If a human target is identified, the sighting device can be triggered to enter an abnormal aiming mode to prevent accidental targeting.

Claim 1

1. A human detection and warning method comprising: acquiring a current scene image within a current field of view of a sighting device; determining whether there is a human target being currently aimed at based on a target recognition result of the current scene image and a position of an aiming mark in the current scene image; and triggering the sighting device to enter an abnormal aiming mode if there is a human target being currently aimed at; wherein determining whether there is a human target being currently aimed at based on the target recognition result of the current scene image and the position of the aiming mark, comprises: performing target recognition with respect to the current scene image to determine a human target contained in the current scene image and mark the human target: determining the position of the aiming mark in the current scene image; determining whether the human target is currently being aimed at based on a position of a marking of the human target being marked and the position of the aiming mark in the current scene image; or, determining a position of the aiming mark in the current scene image, and performing target recognition with respect to a predetermined area image corresponding to the position of the aiming mark; determining, based on the target recognition with respect to the predetermined area image, whether there is a human target present within the predetermined area image corresponding to the position of the aiming mark to determine whether there is a human target being currently aimed at. acquiring a current scene image within a current field of view of a sighting device; determining whether there is a human target being currently aimed at based on a target recognition result of the current scene image and a position of an aiming mark in the current scene image; and triggering the sighting device to enter an abnormal aiming mode if there is a human target being currently aimed at; wherein determining whether there is a human target being currently aimed at based on the target recognition result of the current scene image and the position of the aiming mark, comprises: performing target recognition with respect to the current scene image to determine a human target contained in the current scene image and mark the human target: determining the position of the aiming mark in the current scene image; determining whether the human target is currently being aimed at based on a position of a marking of the human target being marked and the position of the aiming mark in the current scene image; or, determining a position of the aiming mark in the current scene image, and performing target recognition with respect to a predetermined area image corresponding to the position of the aiming mark; determining, based on the target recognition with respect to the predetermined area image, whether there is a human target present within the predetermined area image corresponding to the position of the aiming mark to determine whether there is a human target being currently aimed at.
