Abstract: At present, the research of network situational awareness mainly focuses on situation data fusion, situation assessment and visualization. The data of cyberspace situation is large-scale and high dimensions. The information of current network space situation awareness is discretization, in different standards and different form. Also it is difficult to describe the geographical attributes accurately. To solve the above problems, from the basic concept of cyberspace, this paper which is based on the geospatial information grid, studies the network space physical domain, logic domain and social domain partition method respectively. It establishes the physical, logic and social domain grid. Finally, it describes the connotation and different grid visualization method, provides support to visualizing the situation of geographic space and cyberspace.yPXag8879环亚手机|首页主页

摘要:具备自主定位功能的智能无人机正逐渐成为当前无人机发展的重要趋势。小型与微型无人机的负载、成本与飞行能力有限,无法搭载载重较大的定位系统,而所搭载的低精度IMU无法满足无人机自主定位的需求。利用简便低廉的单目相机构建单目SLAM系统,通过扩展卡尔曼滤波器与低精度IMU信息相融合,可以实时估计单目SLAM系统所生成的稀疏点云地图的真实尺度,并可以较为准确地估计无人机在三维空间中的位姿状态。通过无人机飞行实验,验证了方法的有效性。yPXag8879环亚手机|首页主页

Abstract: It is an important trend in the development of UAV to develop UAVs with the ability of autonomous localization. For small and micro UAVs, due to the limitation of payload, cost, and the ability of flight, it is impossible to fly with the high accuracy but heavy position system and the low accuracy IMU built in small and micro UAVs cannot satisfy the needs of autonomous localization. Mono SLAM system was built with cheap mono camera, fused with the information from IMU of low accuracy based on extended Kaman filter, to estimate the real scale of sparse point cloud map generated by mono slam system and the pose of small and micro UAVs in 3D space. With the experiment of flying, the efficient of the proposed method was approved.yPXag8879环亚手机|首页主页

Abstract: Image data for specific areas are important in many applications, such as military reconnaissance, urban planning, disaster rescue and map updating. Obtaining the image data of a specific area quickly and accurately has been the focus of research in related fields. Unmanned aerial vehicle (UAV) is widely used because of its low cost, flexible take-off and landing, free from weather conditions and so on. But because of the small angle of view, the acquired image needs stitching. The traditional image stitching method is not suitable for rapid mosaic of UAV sequence images. In this paper, the SLAM technology in the field of robot is introduced into the sequence image stitching, and the stitching speed is greatly improved in the process by controlling the splicing area and splicing key frames.yPXag8879环亚手机|首页主页

Abstract: Shadow rendering is important for realistic 3D virtual geographic environment, but there are still very few implementations and applications currently. This paper focuses on some key issues of applying shadow map to global virtual geographic environment. First the sun light direction is calculated for globally arbitrary position and time; then through the compact terrain bounding box, an optimized light frustum calculation method is proposed; finally, for the global browsing has high dynamic range and scale, we put forward a dynamic division algorithm of light frustum based on the principle of cascade shadow map. Through this research, we can achieve high efficiency shadow rendering on global virtual environment.yPXag8879环亚手机|首页主页

Abstract: Parachuting quality evaluation system is a solution to make an assessment after jump training. Parachute simulator data and sampling equipment data solve the problem that there is no training data, which make the parachuting quality assessment system possible. In this paper, in accordance with the need of system, we propose parachuting quality evaluation indicators. Then we use analytic hierarchy process (AHP) to analyze problems, and establish evaluation model. Finally use combination of the weights determining method that combines the subjective methods with the objective methods to determine the weights. The proposed skydiving assessment system makes up the blank of the parachute quality evaluation, and puts forward a new way for using skydiving simulator for training.yPXag8879环亚手机|首页主页

Abstract: The research on maneuver decision-making method is carried out for solving the UAV air combat problems in the complex uncertainty battlefield. Based on the analysis of the factors that reflect the air-combat battlefield situation, the multi-state transition Markov network is used to establish the UAV maneuver decision-making network. The recursive reasoning algorithm based on Markov model is used to make decision reasoning, and the algorithm complexity is analyzed. The simulation results indicate that the decision network can accurately perceive battlefield situation to output the flexible mobile strategy during the air combat process. Algorithm complexity analysis indicates that the multiplication, addition, and division times performed in the reasoning process are 6694840, 3409270, 3470680. In the existing processor computing power, a reasoning cycle can be completed within 40ms, and the network reasoning process can fully meet the real-time requirement of air-combat decision making.yPXag8879环亚手机|首页主页

Abstract: Ogre engine is an open source 3D rendering software which has the command of calculation. The building of terrain, infrared scene rendering and particle effects are three of the typical demands when complex scenes are structured. This paper will take a study of these demands, and propose some implementation in projects. This paper will propose a method for terrain division based on radiographic inspection. It also proposes a method for infrared 3D scene building based on pseudo color and infrared particle effects includes decoy projectile and smoke. Technical verification was carried out in lunar terrain modeling project and ship infrared counteraction project, which meets the demands of high efficiency.yPXag8879环亚手机|首页主页

摘要:时间是作战行动描述的重要参数,对作战行动有重要的约束作用,各作战行动相互之间存在着不同的时间约束,为保证各作战行动在执行时不出现时间上的冲突,需要在执行前进行时间冲突检测。针对作战行动计划时间冲突的检测问题展开研究,通过对作战行动和时间之间的关系进行表达,建立了时间约束网络的数学模型,并采用Bellman—Ford优化算法对时间一致性进行验证,最终对作战行动的时间冲突进行检测。yPXag8879环亚手机|首页主页

Abstract: Time is an important parameter of descriptions of combat actions and has important constraints on combat actions, and time constraints of combat actions are different. To ensure that the time conflict does not occur during the implementation of combat operations, the detection of time conflict is supposed to be done before the implementation. The detection of the time conflict of the operational plan was studied. Through the expression of the relationship between the combat action and the time, the mathematical model of the time constraint network was established, and the Bellman-Ford optimization algorithm was used to verify the time consistency, and the time conflict of the combat action was finally detected.yPXag8879环亚手机|首页主页
