This article introduces the monitoring method of ship navigation under the situation of existing mission. Mission process monitoring and monitoring tips feedback can be achieved through data structuring, current mission accessibility, and final mission accessibility calculation. When the mission can’t be performed as required, calculate the navigation adjustment strategy and mission adjustment strategy, give the best adjustment suggestion to help commanders to make corrections. The algorithm process allows man-in-loop, when the commanders adjust the mission based on strategy, the subsequent calculations will be updated synchronously to meet the real-time and effectiveness of calculating.
With the rapid development of software and hardware technology, the technical requirements for coordinated task action are constantly updated, and the order of coordinated task action needs to be automated and judged more quickly and effectively to meet the task requirements. In order to improve the efficiency and effectiveness of the cooperative task action planning process, this paper forms and calculates the basic characteristics of the cooperative task action network diagram by means of the cooperative task action network diagram, so as to realize the automatic processing of tasks and determine the sequence of cooperative actions.
Objective and accurate lesion assessment is one of the key factors for the optimal photodynamic therapy (PDT) of Port Wine Stains (PWS). The evaluation method based on 3D point cloud can effectively solve the problems. Comparing to the traditional point cloud registration algorithms such as ICP which tend to global registration, the feature description method is more suitable for facial point clouds fusion since each clouds is obtained from different angle and just overlap in certain area. In this paper, the method of fusion of multiple point clouds is applied, in which point cloud fusion is achieved by characterizing randomly selected sampling points. The point cloud fusion result is obtained by matching the public area between the two point clouds. Several fusion experiments are designed and conducted using the facial point cloud acquired by Artec Eva three-dimensional scanner. The experimental results show that it can accomplish the point cloud fusion of patient facial point cloud (including all the information on the skin lesions of PWS), which could be an efficient support for effective 3D lesion assessment.
