Embodiment 1

[0021] Such as figure 1 The shown lifebuoy throwing equipment based on machine vision positioning includes a throwing arm 1, a mobile platform 2, a vision system, a host computer 3 and a wireless handheld remote control 4, and the throwing arm is fixed on the top of the mobile platform. see figure 2 , the bottom of the mobile platform is provided with four mecanum wheels 5, these four mecanum wheels are all controlled by independent servo motors 6, and the two servo motors on the same side are connected with a dual-circuit motor servo controller 7, each A wireless receiving module is arranged in a two-way motor servo controller. Two 360-degree universal rockers are arranged on the wireless handheld remote controller, and a single-chip processing unit and a wireless transmitting module are arranged on the circuit board of the wireless handheld remote controller. see image 3 , rotate the universal rocker, the single-chip processing unit generates a set of instructions accor...

Embodiment 2

[0027] In this embodiment, the control mode of the lifebuoy throwing device in the first embodiment will be introduced.

[0028] The control method of the lifebuoy throwing equipment based on machine vision positioning includes the following steps:

[0029] First, use the camera to collect sea surface image information;

[0030] Then, the image processing unit performs image preprocessing on the collected images to extract a navigation reference line; the image processing unit calculates the navigation information according to the navigation reference line and the relative position between the mobile platform and the navigation reference line, and the navigation information is the horizontal center of the mobile platform. The lateral offset between the position point and the navigation line;

[0031] Finally, the display visually presents the navigation reference line and navigation information to searchers. The navigation information on the display is displayed as a one-way ...

Abstract

The invention provides a lifebuoy throwing device based on machine visual positioning, and a control mode thereof. The lifebuoy throwing device based on machine visual positioning includes a throwingarm, a mobile platform, a visual system, a host computer and a wireless hand-held remote controller, wherein the throwing arm is fixed on the top of the mobile platform; the visual system includes a camera, a light supplement lamp, an image processing unit and a display screen; the camera and the light supplement lamp are fixedly arranged on the throwing arm through a support; the image processingunit is arranged in the host computer; the display screen is embedded into the host computer; the camera acquires sea surface image information; the image processing unit performs image preprocessingon the acquired images, and a navigation base line is extracted, and then the image processing unit calculates the navigation information; the display screen visually displays the deviation between the navigation information and the navigation base line to a search and rescue person; and then the search and rescue person manually adjusts positioning of the throwing arm according to the navigationdeviation, so that the throwing positional precision of a lifebuoy becomes higher.

Description

technical field [0001] The invention relates to a lifebuoy throwing device, in particular to a lifebuoy throwing device based on machine vision positioning and a control method. Background technique [0002] Ships will inevitably encounter various accidents and dangers when they go to sea, so it is essential to equip ships with life buoys. At present, the throwing of the lifebuoy is mainly completed by the throwing equipment. After manual positioning, the throwing equipment will throw the lifebuoy near the person who fell into the water. However, search and rescue personnel only rely on visual inspection to determine the position of the person who fell into the water, and the positioning accuracy is low. Especially in the dark night, search and rescue personnel cannot accurately throw the life buoy by naked eyes. Contents of the invention [0003] The object of the present invention is to provide a lifebuoy throwing device and control method based on machine vision positi...
