The monotonous blows of woodcutter's axe or carpenter's mallet, the splashing of oars, the merry voices of the naked little children at play, the plaintive tune of the ryot's song, the more dominant creaking of the turning oil-mill, all these sounds of activity do not seem out of harmony with murmuring leaves and singing birds, and all combine like moving strains of some grand dream-orchestra, rendering a composition of immense though restrained pathos.

伐木工的斧头或木匠的木槌单调的撞击声，船桨击打河水的声响，裸露着身体的小孩玩耍发出的欢笑声，农夫们哼出的忧怨的曲调，转动的压油机吱吱作响的声音盖过了其它的声音，这一切所发出的声音与树叶的低语和百鸟鸣啭好像没有不协调的音律，这一切结合在一起宛若一个盛大的梦幻般的交响乐队奏出的动人的乐曲，透过淡雅的伤感传递出一首异常美妙的乐章。

In the traditional experimentation of farming , we must do scarification,shoveling, pressing the time between every two working procedure is long,the efficiency is low,and it will also expand a large number of the labour order to work out this problem ,we should create a new kind of can take the place of -speed digital multifunctional soil bin carriage is one equipment which can acord with these can do scarfication,shoveling,pressing at the same time ,and it can control each working procedure shortens the time between every two working procedure,and improve the efficiency.

传统的耕作试验需要单独进行松土、铲平、压实、旋耕等工序，各工序的间隔时间较长，效率较低，而且要消耗大量的劳动力，为了解决这一问题，我们迫切的需要研制出一种新型的机械设备，用它来代替人力。高速数字多功能土槽试验台车正是要符合这些要求的一种机械设备，它能够将松土、铲平、压实、旋耕等各道工序连为一体，并且能够单独控制各道工序。

Firstly, a signalized point is stuck on a moving object to be tested, a microphone array and two video cameras are arranged, and the video cameras are demarcated to obtain a projection matrix; sound pressure signals of a sound source in the moving object to be tested are obtained by the microphone in an array mode, the dynamic video of the moving object to be tested is obtained and disassembled into an image by the video cameras; the signalized point on the moving object to be tested is identified in the video image and the matched signalized point is treated with three-dimension reconstruction to obtain the spatial location of the moving object to be tested; the sound pressure signals are treated with beam forming treatment to obtain a sound field characteristic function scattergram of the moving object to be tested, the video image is treated with spatial coordinate superposition frame by frame and restored into a dynamic video image.

首先在被测运动物体粘贴标志点，布置传声器阵列和两台摄像机，对摄像机进行标定，得到投影矩阵；传声器阵列获取被测运动物体中声源的声压信号，摄像机获取被测运动物体的动态视频，将动态视频拆解成图像；在视频图像中识别出被测运动物体上的标志点，对匹配后的标志点进行三维重构，获取被测运动物体的空间位置；对声压信号进行波束成型处理，得到被测运动物体的声场特征函数分布图，将其视频图像进行逐帧空间坐标叠加，并还原成动态视频图像。
