Test device and method for obtaining maximum resolution of image in karst cave water environment

Abstract

The present invention provides a test device and method for obtaining the maximum resolution of an image in a karst cave water environment. A true-color camera and a light supplementing device are disposed on an adjustable bracket; a resolution test card and a transparent sink are arranged on a fixed frame; the true-color camera, the light supplementing device, the transparent sink and the resolution test card are located on the same vertical plane; the position of the light supplementing device is higher than that of the true-color camera; the lens of the true-color camera and the center of the resolution test card are located on the same plane; the transparent sink is disposed between the true-color camera and the resolution test card; the resolution test card is disposed at the outer side of the transparent sink; the transparent sink has an accommodating space for accommodating different dissolution media; a turbidity tester measures the turbidity of a tested solution; a controllerreceives the test values of the turbidity tester and the resolution test card; a quadratic parabola function is adopted to fit data under different light supplementing intensities; and the variation law of a maximum resolution corresponding to the light supplementing intensities can be determined.

Description

technical field

[0001] The disclosure relates to a test device and method for obtaining the maximum resolution of an image in a cave water environment. Background technique

[0002] Underwater imaging is an important research direction of underwater optics and ocean optics. It is an important means and tool for humans to understand the ocean, develop and utilize the ocean, and protect the ocean. It has the advantages of intuitive detection targets, high imaging resolution, and high information content. As mentioned above, this technology has been widely used in seawater target reconnaissance / detection / recognition, underwater archaeology, seabed resource exploration, biological research, underwater engineering installation / overhaul, underwater environment monitoring, lifesaving and salvage and other fields.

[0003] But in the field of underground engineering, with the continuous expansion of the scope of tunnels and subways, the construction of tunnels and subways in karst a...
