Problems solved by technology
Research in these fields requires high-precision positioning of maritime targets. However, due to large swings in the sea surface, it is difficult to obtain high-precision measurement results. Therefore, how to improve the positioning accuracy of maritime targets has become a research topic in the field of maritime detection. primary issue
[0003] The current commonly used radio positioning method is prone to clutter interference due to reflection and refraction at sea. At the same time, the sea surface measurement platform is swaying, so the measurement results are often unsatisfactory. If you want to improve the accuracy, you need more equipment assistance to eliminate the impact , but doing so would greatly increase research costs

The invention provides a maritime dynamic target positioning system and a positioning method thereof. The maritime dynamic target positioning system comprises a general control unit, a data processing unit, a positioning unit, a cooperative target, a first camera and a second camera. A horizon inclination angle is used for correcting the sea surface swing error, and the technical problem that the result error is large due to the fact that a target position measuring platform at sea swings is solved. The invention further provides a relative measurement method which is combined with an image interpretation technology to determine the marine dynamic target position, so that the measurement precision of the maritime dynamic target position is improved.
Description
technical field [0001] The invention relates to the field of marine measurement, in particular to a marine dynamic target positioning system and a positioning method thereof. Background technique [0002] With the continuous development of modern economy and technology, the marine industry has expanded from the original maritime transportation to the fields of marine resource investigation, marine engineering construction, marine scientific research, and maritime military affairs. Research in these fields requires high-precision positioning of maritime targets. However, due to large swings in the sea surface, it is difficult to obtain high-precision measurement results. Therefore, how to improve the positioning accuracy of maritime targets has become a research topic in the field of maritime detection. primary issue. [0003] The current commonly used radio positioning method is prone to clutter interference due to reflection and refraction at sea. At the same time, the sea...
