Design Of City Police UAV Based On Perceptual Imagery

UAV(Unmanned Aerial Vehicle,abbreviated UAV)is short for Unmanned Aerial Vehicle,is a kind of using radio remote control equipment,bring your own program control device,it can carry all kinds of payload complete all assigned tasks air Vehicle [1].Staff by ground station on the remote control,positioning and data transmission,because of its simple manipulation,strong mobility,high efficiency and the advantages of the wide scope of work,gradually replace man to finish many unable to complete tasks.In recent years,unmanned aerial vehicles have become more and more widely used in non-military fields,such as police,forestry and urban planning.However,there are relatively few UAV products dedicated to the police field.Aiming at this point,in order to cope with the problem of police daily attendance,innovative design of UAV is designed to better meet the needs of urban police.First of all,a comprehensive and in-depth understanding of the UAV,review of the UAV platform research history and development status,analysis and comparison of domestic and foreign companies and research institutes designed UAV,and the survey results were summarized,Explain the main content of this paper.Secondly,based on a comprehensive understanding of the history and current situation of research and development of UAV,this paper analyzes SET(socio-economic-technological)factors of UAVs to find out the product breakthrough and ensure the correct direction of product research.Thirdly,using the sentimental imagery to study the connection between the modeling and the image of UAV in urban police.The first phase,extensive collection of UAV images of words and product samples.In the second stage,we selected 30 social sciences,economy,technology,police,product and urban environment as the constraints to filter and subdivide the UAV imagery words,which were used as the next step of research.At the same time,we screened the product samples into 15 groups.The third stage,through the principal component analysis in factor analysis,simplifies the 30 words and extracts the least representative typical words.In the fourth stage,the UAV shape modeling was divided into five main constituent units.The five main constituent units were subdivided and simplified element diagrams were established.The 15 unmanned aerial vehicle samples and the extracted simplified shape elements were coded One by one to get the classification of morphological elements of each sample code table.And according to the image of the image to match the description of the sample corresponding to the shape element coding,extraction UAV modeling feature elements.Finally,the implementation technologies of UAV related problems,such as flight controller,multi-sensor,positioning and navigation,etc.are analyzed and solved.According to the working environment factors of UAV,this paper analyzes the shape,color and material of urban police UAV,and makes a draft sketch of UAV modeling,selects the scheme by the method of fuzzy evaluation,finally uses Rhino modeling software And Key-shot rendering software to complete the city police drone concept prototype design.
