Problems solved by technology

[0003] However, in the visible light image, the contrast between the water level gauge and the water area is low, so that various external factors, such as water level gauge dirt, corrosion, water surface reflection, sun glare, etc., will reduce the clarity of the visible light image, resulting in inaccurate water level detection results

Embodiment approach

[0147] The image acquisition device includes: a spectroscopic unit, a visible light imaging unit, a non-visible light imaging unit, an image processing unit, a registration unit, a supplementary light unit and an output unit.

[0148] The light splitting unit decomposes the incident light into visible light signals and non-visible light signals. The visible light imaging unit performs imaging based on the visible light signal to obtain a visible light image. In addition, the pre-obtained calibration data is also input to the visible light imaging unit, so that the visible light image carries the calibration data. The non-visible light imaging unit performs imaging based on the non-visible light signal to obtain a non-visible light image.

[0149] The registration unit registers the visible light image and the non-visible light image, and sends the registration result to the image processing unit. The non-visible light imaging unit sends the non-visible light image to the ima...

Abstract

The embodiment of the invention provides image an image acquisition equipment, water level detection equipment, a water level detection method and a storage medium. The image acquisition equipment comprises a visible light imaging unit which is used for imaging a visible light signal reflected by a water gauge, and obtaining a visible light image of the water gauge, an invisible light imaging unitwhich is used for imaging an invisible light signal reflected by the water gauge to obtain an invisible light image of the water gauge, and an image processing unit which is used for determining coordinates of a water line in the invisible light image of the water gauge and calculating water level data according to the calibration data in the visible light image of the water gauge and the coordinates of the water line in the invisible light image of the water gauge. A water area has high absorptivity to non-visible light, the contrast ratio of the water area and the water gauge in the non-visible light image is high, and and therefore, influence of various external factors on the image definition is reduced, so that the accuracy of the water line detected in the non-visible light image ishigh, and the accuracy of a water level detection result is improved.

Description

technical field [0001] The invention relates to the technical field of water level detection, in particular to an image acquisition device, a water level detection device, a method and a storage medium. Background technique [0002] The relevant water level detection scheme generally includes: installing a water level gauge in the water area to be detected, a visible light camera collects a visible light image of the water level gauge, and determines the water level of the water area by analyzing the visible light image. [0003] However, in the visible light image, the contrast between the water level gauge and the water area is low, so that various external factors, such as water level gauge dirt, rust, water surface reflection, sun glare, etc., will reduce the clarity of the visible light image, resulting in inaccurate water level detection results. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an image acquisit...
