3D camera rig for easy underwater shooting}

The present invention relates to a 3D camera rig that facilitates underwater photography in which underwater cameras are fixedly arranged, particularly when performing underwater 3D imaging to check underwater hull pieces and relics, such as underwater cultural heritage investigation.

More specifically, it relates to a 3D camera rig for easy underwater photography that can be applied particularly appropriately when performing fast and accurate underwater photography within the limit of a short diving time in order to photograph the sinking of the hull in a circular state. will be.

More specifically, 5 high-resolution compact 3D cameras for securing 3D digital images can be easily installed, so that when shooting an underwater object vertically, it can shoot not only east, west, south, north, but also flat surfaces, making it easy to take 3D underwater photography with improved quality of use It's about the camera league.

More specifically, it is possible to shoot safely, quickly, and accurately with both hands even during underwater currents, and to adjust the size of the camera rig so that the shooting height can be changed according to the underwater field of view, so that it can be easily carried while carrying. It is about a 3D camera rig that makes underwater photography easy.

In general, when searching for an object in the water or obtaining an image signal of an underwater object, in order to improve the efficiency and probability of the operation, the camera acquires and records the images in the remaining 5 directions in real time except for the upward direction to the surface of the water. There is a multi-directional underwater image acquisition and shooting system for

One of them is Korean Utility Model Application No. 20-2003-0029441 (Name: Underwater Image Acquisition System with Multi-Directional Video Camera for Investigation/2003.09.17.), and as is known in the Gazette, In the device having a camera and a lighting device and capable of observing a subject in water, a plurality of cameras installed to observe an image of an object from multiple directions, and a plurality of cameras to obtain a clearer image by interworking with the camera module A lighting unit illuminating the direction, a position information acquisition unit indicating the current position information of the vessel in conjunction with GPS, a water depth sensor built in the camera module to transmit the water depth of the point where the camera is located on the ship, and the camera; A signal processing unit that converts signals received through a module, a location information and a water depth sensor into digital signals and converts them into image signals and text signals, and a display panel for displaying the image signals and text signals processed by the signal processing unit consists of

However, the underwater image acquisition system has a problem in that its structure is complicated, and the usability is deteriorated due to poor workability and post-patency.
