代码说明:

  本算法在Matlab2008b 环境下实现。包括main,san 和ssd 三个函数。 这次实现的算法并不是比较两个已经知道的点是否匹配,而是已知一个图形中的特征点,在另外一个图像中找到与其最匹配的点,匹配度用SAD 或者SSD 来度量。 main.m 是程序的入口,包括生成和读入实验数据,调用sad 函数和ssd 函数求匹配点,最后绘 制出最后的结果。sad.m 是用sad 度量方法在另一图中求解匹配点的函数实现,有3 个参数 y=sad(x,image1,image2)。其中x 是代匹配的数据,image1 是图像1 数据,image2 是图像2 数据。 从理论上分析,ssd 比sad 算法要复杂一点,经过测试,在一幅640*480 的图像中寻找10 个匹配点数据SAD 用时25.062519 秒,SSD 用时25.291432 秒。(The algorithm Matlab2008b environment to achieve. Including the main, san, and ssd three functions. The implementation of the algorithm is not the point of comparing two matches already know, but the known feature points in a graphic, an image found in the other match with the most points, matching measured with the SAD or SSD. main.m is the entry, including the generation and reading test data, call the sad ssd function evaluation functions and matching points, and finally draw the final result. sad.m measure is sad figure in another match point in the function implementation to solve, there are three parameters y = sad (x, image1, image2). Where x is the generation of matching data, image1 is the data image 1, image2 is the image 2 data. From the theoretical analysis, ssd little more complicated than the sad algorithm, tested in a 640* 480 images of 10 match points in the search for data using time 25.062519 seconds SAD, SSD with time 25.291432 seconds. )

    针对粒子概率假设密度(PH D)滤波算法在虚警、漏检情况下,b标状态估计不稳定和b标可观测性车弱的问题,提出了一种基于序贯融合的粒子PH D滤波方法,利用雷达和红外传感器多目标进行融合跟踪杏基本思想是先对红外传感器进行粒子PH D滤波,丙将红外传感器滤波结果作为雷达的预测值,然后利用P达观测的数据进行更新,这样通过雷达和红外传感器交替上作保证目标状态的可观测性,从滤波器输出结身即可得到目标的状态信息仿真结果表明,在虚警、漏检和密集目标环境下,该方法是有效的和稳健的(The problem of target state estimation instability and observability weakerin the presence offalse alarms and missed detection was deal with. On the basis of sequential fusion, a particleprobabil- ity hypothesis density(PHD) filter for multrsensor multrtarget tracking was proposed. Observed da to collected from the infrared sensor was estimated with the particle PHD filter. Then the results from the filter were set as the radar predicted value by the radar observations. The multrtarget state can be updated to guarantee observing the target state. In this way, the global state is updated at the fusion center. Simulation results show that the proposed algorithm is effective and robust under the false warning, omission and concentrated target environment. )
