摘　　要：随着消费级无人机的快速发展,无人机航拍照片逐渐成为目的地形象研究的新型资料来源,并为观察视角从地面转向空中提供支撑。以西藏自治区为案例地,以论坛“天空之城”中无人机航拍照片、文本简介和位置坐标为数据,基于目的地形象感知理论中的“认知—情感”模型,运用计算机视觉分析、计算机文本情感分析、社会网络分析和GIS空间分析等方法对无人机视角下西藏目的地形象感知进行探索。研究发现,自然景观在所有视觉认知形象中占比最大,雄伟的山脉和壮阔的水景是无人机视角下西藏最突出的视觉认知形象;照片文本简介以积极情感为主,其数量远多于中性情感和消极情感,消极情感主要来自恶劣的环境对拍摄和自驾造成的影响;西藏整体形象体现在壮丽的高原风光和独特的藏式建筑,具体包含“雄壮山川”“圣洁水域”“高原牧歌”和“藏地建筑”4个元素,整体形象感知正向积极。视觉形象空间分布整体呈现“东—西”方向分布的“一核多片”格局。最后从无人机摄影者、无人机设备、无人机视角和目的地视觉营销与建设四方面探索西藏目的地视觉形象地-空转换机制,并基于环境资源和无人机特点为西藏目的地形象建设提出了优化建议。With the rapid development of consumer-grade unmanned aerial vehicles(UAVs),aerial photographs from UAVs become a new source of data for destination image research,and provide support for the observation perspective from the ground to the sky.Taking Tibet as the research object,this study used UAV aerial photos,text profiles and location coordinates in the forum"SkyPixel",based on the"cognitive-emotion"model in destination image perception theory,applied computer vision analysis,social network analysis,computer text sentiment analysis and GIS spatial analysis to explore the perception of destination image in Tibet from the perspective of UAVs.The research results show that:The natural landscape accounts for the largest proportion of all visual cognitive images,and the majestic mountains and magnificent water features are the most prominent visual scenes of Tibet from the perspective of UAVs.The text profile of the photo is dominated by positive emotions,and the number of positive descriptions is far more than neutral and negative emotions.Negative emotions mainly come from the impact of difficult environments on shooting and self-driving.The overall image of Tibet is reflected in the magnificent plateau scenery and unique Tibetan architecture,specifically in four aspects:"magnificent mountains and rivers","holy waters","plateau idyll"and"Tibetan architecture",and the overall image perception is positive.The spatial distribution of the visual image reveals a pattern of"One core and multi-segment areas"distributed in"east-west direction".Finally,this study explored the ground-sky transition mechanism of Tibet destination visual image from four aspects:UAV photographer,UAV equipment,UAV perspective,destination visual marketing and construction,and put forward optimization suggestions for Tibet destination image construction based on the characteristics of environmental resources and UAVs.
