an underwater camera

Abstract

The invention discloses an underwater camera, including an imaging mechanism, which is characterized by a whiteboard, a correction lens, a waterproof casing, an imaging lens, a range finder, an imaging processing and control system, an end cover, a waterproof connector, a channel and a water entry detection device The imaging mechanism is composed of an imaging lens and an imaging processing and control system. The correction lens, waterproof casing, end cap, waterproof connector, and water entry detection device form a closed cavity, and the imaging mechanism and the range finder are located inside the closed cavity. , the whiteboard is placed on the outside of the waterproof enclosure and is in view of the imaging mechanism. The invention has the characteristics of compact structure, low failure rate and good safety, can measure the size of the water surface and underwater objects in real time and the relative position between the measured object and other objects, can automatically change the water surface and underwater shooting modes, and is suitable for various Various underwater engineering, underwater operations and underwater detection.

Description

technical field [0001] The invention relates to a camera, in particular to an underwater camera, which belongs to the underwater imaging that can measure the size of the water surface and underwater objects in real time and the relative position between the measured object and other objects, and can automatically change the water surface and underwater shooting modes The device has the advantages of real-time measurement, automatic switching of shooting modes and effective image color restoration, and is suitable for various underwater engineering, underwater operations, underwater detection and other fields. Background technique [0002] There are many underwater cameras given in the prior art, eg. [0003] The invention patent application with publication number CN102870044A "Underwater Camera with Pressure Sensor" includes: a waterproof case; an image sensor for capturing digital images; an optical system for imaging a scene onto the image sensor; means for measuring pre...

AI Technical Summary

Problems solved by technology

[0005] Existing underwater cameras are generally equipped with a monocular imaging mechanism in the waterproof casing. Because of this structure, objects with different sizes and different object distances may have the same coordinates in the phase plane coordinate system after being imaged in the camera, making the camera There are errors in the measurement of the measured object; in addition, due to the absorption of specific spectra by water, the imaging of underwater objects has color deviation in the camera, and the color temperature of the light may be inconsistent in each imaging, so the underwater object There will also be difficulties in the color restoration of the underwater camera. The above-mentioned structure makes the underwater camera still need to be improved in terms of practicality.
