Embodiment 1

[0029] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for adjusting the brightness of navigation aids based on light pollution evaluation, comprising the following steps:

[0030] S1. Obtain the original image of the water area where the navigation mark is located, and identify the navigation mark in the original image;

[0031] S2. Taking the navigation mark as the center, intercepting an area of ​​a set range in the original image as an evaluation image;

[0032] S3. Calculating the brightness contrast between the navigation mark and the background in the evaluation image;

[0033] S4. Evaluate the background light pollution degree of the navigation mark according to the brightness contrast;

[0034] S5. Adjust the brightness of the navigation mark according to the evaluation result.

[0035] The ability of ship drivers to recognize navigational navigation marks is determined by the brightness contrast between the navigation mark and th...

Embodiment 2

[0076] Embodiment 2 of the present invention provides a navigation mark brightness adjustment device based on light pollution evaluation, hereinafter referred to as the navigation mark brightness adjustment device, including a processor and a memory, and a computer program is stored on the memory, and when the computer program is executed by the processor , realizing the method for adjusting the brightness of the navigation mark based on the light pollution evaluation provided by the embodiment 1.

[0077] The brightness adjustment device of the navigation mark based on the light pollution evaluation provided by the embodiment of the present invention is used to realize the brightness adjustment method of the navigation mark based on the light pollution evaluation. The device is also available, and will not be repeated here.

Embodiment 3

[0079] Embodiment 3 of the present invention provides a navigation mark brightness adjustment system based on light pollution evaluation, including the navigation mark brightness adjustment device 1 based on light pollution evaluation provided in Embodiment 2, and also includes a navigation mark 2 and a photosensitive unit 3;

[0080] The photosensitive unit 3 is used to take the original image of the water area where the navigation mark is located, and send the original image to the light pollution evaluation-based navigation mark brightness adjustment device 1;

[0081] The navigation mark 2 is used to receive the evaluation result sent by the light pollution evaluation-based navigation mark brightness adjustment device 1, and adjust its own brightness according to the evaluation result.

[0082] The system includes a photosensitive unit 3, a navigation mark brightness adjustment device 1 and a navigation mark 2; the navigation mark brightness adjustment device 1 can be integ...

Abstract

The invention relates to the technical field of navigation mark identification, and discloses a navigation mark brightness adjusting method based on light pollution evaluation. The method comprises the following steps: acquiring an original image of a water area where a navigation mark is located, and identifying the navigation mark in the original image; intercepting an area in a set range in theoriginal image as an evaluation image by taking the navigation mark as the center; calculating the brightness contrast between the navigation mark and the background in the evaluation image; evaluating the background light pollution degree of the navigation mark according to the brightness contrast; and adjusting the navigation mark brightness according to the evaluation result. The method has the technical effect of improving the identifiability of the navigation mark.

Description

technical field [0001] The invention relates to the technical field of navigation mark identification, in particular to a method, device, system and computer storage medium for adjusting brightness of navigation mark based on light pollution evaluation. Background technique [0002] Navigation marks are important symbols to help and guide ships to navigate, indicate the direction of the channel, boundaries and obstructions. Whether the navigation mark can work normally is related to the navigation safety of the ship and even the life safety of the crew. With the industrialization and urbanization of society, light pollution has become the fifth largest pollution. It is a new type of pollution after air pollution, water pollution, noise pollution and solid waste pollution, and its scope of influence gradually increases from land to navigable waters, especially The use of light sources such as high-brightness lighting and urban lighting supporting landscape lights has made li...
