Nowadays, the complexity of image processing algorithm is more and more high, the amount of data in image processing is more and more large, and the real-time performance of image processing is very important. In order to solve the problems of im- age preprocessing and real-time video stream data, this paper presents a method of image acquisition and processing system based on FPGA and OV5640 using Sobel operator for edge detection. FPGA transmits the video stream data collected by OV5640 camera to SDRAM, which is processed by Sobel operator template and then is displayed through VGA. The design is based on EP4CE10F17C8, which is the FPGA chip of the Cyclone IV series of Intel company. The experimental results show that the real- time processing of video stream data can be realized by using pipeline design and ping-pong operation based on FPGA and Sobel edge detection algorithm.

In the classical DV-Hop algorithm, the estimation of unknown point coordinates by the hop distance and least squares method will lead to large errors. To solve this problem, a weighting factor is introduced to correct the average hop distance, and a simulated annealing algorithm is used instead of the least squares method to solve the unknown node coordinates. The number of beacon nodes and communication radius are taken as variables to study the improvement effect. The experimental results show that the positioning accuracy of the improved positioning algorithm is significantly improved, and the error rate is significantly reduced with fewer beacon nodes and smaller communication radius, which has higher practical application value.

As one of the most vigorous industries in the new era, China's tourism industry has undergone changes in just a few de- cades. However, it is not difficult to find that the mainstream travel website on the network are hotels and air ticket booking as the core. Few websites provide users with the auxiliary function of travel decision. This makes it difficult for people to quickly and con- veniently understand the current tourism hotspots and provide appropriate travel plans. With the rapid development of information technology, Internet technology and computer technology, WebGIS is entering people's life and gradually becoming a topic of con- cern for Web applications. Network geographic information system is also becoming a popular information tool. Therefore, this pa- per establishes a tourism information decision system based on WebGIS, which will start from the perspective of geographic infor- mation system and carry out information optimization based on ant colony algorithm. It uses WebGIS to realize the function of que- ry and analysis of tourism spatial information and provide users with intelligent travel route planning.

Crowd testing mode is a new testing mode rising with the development of the Internet.

There is a large number of civil aviation air traffic control terminal equipment. When the equipment fails to maintain, the space is narrow and easy to cause other faults, which may cause certain interference to the controller's command when handling on- site faults. The above problems can be avoided by sinking the control terminal equipment with optical fiber matrix technology. The new air traffic control room has been used in some areas. This paper mainly discusses how to design and use optical fiber matrix equipment to sink the control terminal equipment and ensure the safety and reliability of the control and operation equipment.

With the development of science and technology, the information construction of many universities has begun to move from digital campus to smart campus.

Since the existing algorithm LapSRN only using the robust Charbonnier loss and traditional convolution kernel，it can cause model cannot extract more high-frequency information and have relatively small receptive filed. In this paper, we use structur- al loss combined with robust Charbonnier loss and use dilated convolution kernel to replace the traditional convolution kernel to im- prove the performance of our model. Experimental results show that our model can extract more high-frequency information and the quality of reconstructed image has been improved, meanwhile it doesn’t increase the complexity of model.

With the rapid development of information technology, information technology specialty has a very broad employment prospect. At present, higher vocational colleges face opportunities and challenges as a training base for skilled talents. Although many higher vocational colleges have opened information technology specialties, they have not been able to combine local and re- gional industry characteristics, and there are a series of problems such as fuzzy professional positioning, development lagging be- hind the market, unscientific curriculum system, and backward experimental training conditions. This paper puts forward some ideas for professional construction from the four aspects of top-level positioning, integration of production and education, curriculum sys- tem and training resources construction.
