Embodiment Construction

[0021] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0022] figure 1 It schematically shows the overall flow chart of the monocular wide-angle vision anti-theft alarm method for an intelligent robot according to a preferred embodiment of the present invention.

[0023] like figure 1 As shown, the monocular wide-angle vision anti-theft alarm method of an intelligent robot according to a preferred embodiment of the present invention includes:

[0024] Feature point acquisition step S1: Acquire feature points of the detection environment when the monocular wide-angle camera is at a predetermined angle;

[0025] Preferably, the predetermined angle state is a state of the monocular wide-angle camera at a maximum rotation angle.

[0026] This is an initialization stage, in which the stability of the ...

Abstract

The invention discloses an intelligent robot monocular wide-angle vision theft prevention alarming method. The method comprises steps: feature points of a detection environment when a monocular wide-angle camera is in a predetermined angle state are acquired; in a condition in which the monocular wide-angle camera is kept still and is in a predetermined angle state, a picture photographed by the monocular wide-angle camera is selected as a template, the template is compared with a picture later photographed by the monocular wide-angle camera, and when the difference between an image pixel point matrix of the template and an image pixel point matrix of the picture photographed later is larger than a predetermined threshold, an abnormality processing step is started; in a rotating state of the monocular wide-angle camera, the matching ratio of the feature points of the picture photographed by the monocular wide-angle camera and the feature points acquired in a feature point acquisition step is detected, and when the matching ratio is lower than a predetermined matching threshold, an abnormality processing step is started; and according to face detection results of multiple pictures photographed by the monocular wide-angle camera after the abnormality processing step is started, abnormality alarming processing is executed.

Description

technical field [0001] The invention relates to the field of intelligent robots and the field of home anti-theft alarm, more specifically, the invention relates to a monocular wide-angle visual anti-theft alarm method for an intelligent robot. Background technique [0002] Existing home anti-theft alarms generally rely on alarm hosts, door magnets, wireless infrared detectors, wireless smoke detection alarms, smoke gas detectors, infrared light barriers and other equipment to achieve anti-theft alarms. [0003] The anti-theft alarm system is divided into three parts functionally: the detection part, the on-site processing part, and the follow-up processing part. The types of defense probes mainly include door sensors, passive infrared detectors, active infrared detectors, emergency buttons, smoke / fire detectors, flammable gas detectors, etc. These components constitute the detection part of the alarm, and have on-site audio alarm and The alarm host, telephone line, and dedi...
