Description
Technical Field
The utility model relates to a seabed survey and drawing technical field, concretely relates to integrated form data acquisition system suitable for survey and drawing of island reef area shallow water seabed landform.
Background
The investigation technology of the current seabed surveying and mapping field for island region shallow water surveying and mapping mainly comprises satellite remote sensing water depth inversion, sonar water depth measurement, unmanned ship surveying and mapping, underwater landform shooting and the like. The inversion of shallow water landform and landform in the island reef area can be realized by utilizing optical satellite remote sensing data based on a machine learning algorithm, so that mapping of shallow water landform in the island reef area is realized, and the novel mapping technology developed by the integration of aerospace science and technology, remote sensing technology and multiple disciplines in the field of computers in recent years is provided. However, the inversion of the water depth by satellite remote sensing needs to firstly accumulate a large amount of actually measured water depth data in a mapping area, and then the measured result is coupled and compared with the spectrum of the satellite remote sensing data at the same time, so as to form a set of inversion algorithm suitable for a small area. Such a method is obviously not suitable for the first submarine mapping of unknown shallow water areas, and the applicability of the method is very limited because the satellite remote sensing spectral data is also influenced by water color, temperature, surface suspended substances and seasonal changes. During sonar bathymetric survey, seabed mapping is a conventional technical means all the time, but the method can only record seabed bathymetric depth which is a single seabed geomorphic element and cannot reflect real geomorphic morphology and image visualization information of the seabed. In recent years, along with the development of equipment manufacturing industry, unmanned boat surveying and mapping technology comes along, and autonomous surveying and mapping of small-area submarine topography can be achieved. However, the unmanned surveying and mapping boat has the disadvantages of high cost, poor cruising ability and weak wind wave resistance strength, so that the unmanned surveying and mapping boat is difficult to be used for surveying and mapping complex sea conditions in breakwater zones of island and reef shallow water areas. Secondly, unmanned ship survey and drawing can only carry out autonomous navigation according to predetermined route, if can't carry out autonomic decision-making in the proruption situation, probably cause the loss of equipment and instrument. The underwater landform camera shooting is a visual key technology for depicting submarine landforms, and with the integrated development of high-definition camera shooting equipment and an underwater lighting system, the submarine surveying and mapping industry can further improve the acquisition of information such as the submarine landforms and substrates. However, coordinate position information of the underwater topographic image pickup data cannot be determined in the acquisition process, and the submarine topographic image and the water depth measurement result are difficult to be well matched. The technologies can not meet the practical difficulties and task requirements of heavy shallow water surveying and mapping tasks, complex sea conditions and resource limitation in island regions in China.
Therefore, an integrated submarine geomorphic data acquisition system which is cheap and cheap, has high maneuverability and long cruising time, can realize synchronous acquisition of submarine depth and geomorphic image data and adopts a unified time service and coordinate system is extremely needed.
