Abstract

The invention discloses a visual underwater box type sampler and a control method thereof. The visual underwater box type sampler comprises a box type sampler, a binocular imaging subsystem, a receiving end optical transceiver and an upper computer. The binocular imaging subsystem comprises two underwater imagers with completely the same parameters. The underwater imagers are symmetrically installed at the left end and the right end of the box type sampler and synchronously collect underwater target object image sequences. An LED light source, an underwater depth measurer and a control unit are installed beside each underwater imager. Each underwater imager, the corresponding LED light source and the corresponding underwater depth measurer are all connected with the corresponding control unit. All the control units are connected with the receiving end optical transceiver. The receiving end optical transceiver is connected with the upper computer. The visual underwater box type sampleris reasonable in structure and easy to operate, and the marine target sample collecting, optical image data collecting and real-time monitoring can be realized.

Description

technical field [0001] The invention designs an underwater box-type sampler, in particular a box-type sampler for underwater real-time observation and a control method thereof. Background technique [0002] The box sampler is a sediment sampling device with a sampling tube or a sampling cylinder in the shape of a square or rectangular box sampler. It is composed of pipe rack, sampling box, heavy hammer, closing shovel and so on. When the sampler reaches the seabed, the gravity of the hammer makes the sampling cylinder inserted into the seabed sediment, and the closed shovel rotates to cut the bottom sediment into the sampling cylinder. When sampling, the box sampler has little or no disturbance to the sediment and is suitable for taking undisturbed samples. Therefore, it is widely used in marine scientific research and is a common tool for marine geological sampling. [0003] With the gradual advancement of marine scientific research work, the demand for the accuracy of mi...
