服务器程序要完成以下功能：创建监听Socket进行监听，当有客户端请求连接时，建立一个新的接收Socker处理这个客户的数据发送与接收；接受客户端发来的数据，并向客户端返回相应信息，本程序向客户端返回信息为接收到的信息；将接受的信息通过串口1发送出去-Server program to complete the following functions: Create Socket eavesdropping eavesdropping, when client requests a connection, the establishment of a new deal with the customers to receive Socker send and receive data accept client data sent to the client to return to the corresponding information, the procedure to return information to the client to receive the information will accept the information sent through the serial port 1

说明：  VC毕业设计，全景图拼接算法实战源码+论文。算法基本思想，图像A和Ｂ，Ａ有至少１／３部分与Ｂ重合，在Ａ中找图像块ａ，在Ｂ中找图像块ｂ，利用夹角余弦距离，求ａ 、ｂ的相似度，利用循环使ｂ在Ｂ中移动，找到相似度最大的图像块ｂ。通过ｂ所在点坐标，确定B相对于Ａ的偏移量。通过偏移量将Ａ和Ｂ放在同一坐标系实现拼接。(VC graduation design, panorama mosaic algorithm actual source code + thesis. The basic idea of the algorithm is that at least one third of the images A and B overlap with B. Find the image block a in A, and find the image block b in B. Use the cosine distance of the angle to find the similarity of a and b. Use the loop to move b in B to find the image block b with the highest similarity. Determine the offset of B relative to A through the coordinates of the point where b is located. A and B are placed in the same coordinate system through the offset to achieve stitching.)

说明：  he energy generated using a photovoltaic (PV) are depends mainly on meteorological factors such as temperature and solar radiation. Considering the high cost and the low efficiency of a PV system, it must operate at maximum power point (MPP) which changes with the load variations and weather conditions. This article presents the conception of a nonlinear controller for the DC-DC converter to retrieve a maximum power from photovoltaic systems (PV). This is affected via the control of duty cycle of the converter. The backstepping control is used to design the controller. The incremental conductance algorithm provides the output reference voltage PV to the backstepping controller. An integral Action is added in order to render the controller robust against changes of parameters and perturbations. The proposed controller performance is assessed by numerical simulations under changing atmospheric conditions(efficiency of a PV system, it must operate at maximum power point (MPP) which changes with the load variations and weather conditions.
