为了提高交通标志检测的实时性和可行性,提出了一种基于YOLOv8s的轻量化交通标志检测模型。首先,用FasterNet中的残差模块FasterNetBlock替换C2f模块中的BottleNeck,降低模型参数量和计算量;其次,用一种小目标检测层去替换大目标检测层,降低Backbone中网络层数,实现大幅度提高检测速度和降低参数量;最后,用Wise-IOU替换原CIOU损失函数,提高速度和精度。在TT100K交通标志数据集上验证,其与YOLOv8s模型比较,mAP50提高了5.16%,参数量降低了76.48%,计算量降低了13.33%,FPS快了35.83%。与其他模型相比,mAP50平均提高了15.11%,参数量平均降低了85.74%,计算量平均下降了46.23%,FPS平均提高了31.49%。该模型具有检测精度高、参数量少、计算量低、速度快等优点,较原算法有很大地提升,且与其他先进的交通标志检测模型比较时表现出了很强的竞争力,在交通标志检测中具有较大优势。

清代前中期的旅外文献虽然在数量上、涉及范围上均无法与晚清时期相比,但在一定程度上也能反映清代前中期对外交往的格局,以及清人对周边世界的观察。出于册封等原因,清代前中期的旅外文献主要为清廷使臣及随行人员撰写,涉及的区域为琉球、安南与朝鲜等。除个人行纪、诗文外,此类旅外文献还涉及域外国家的风俗、制度等。它们所记的世界在地理上虽是域外,但文化层面上仍是域内。

根据高质量发展内涵,从创新、协调、绿色、开放、共享五个层面建立旅游高质量发展评价指标体系,采用熵权TOPSIS法对2016—2020年中部六省的旅游高质量发展情况进行实证研究。结果表明:时间上,中部六省旅游高质量发展水平在整体呈上升趋势,但各省发展速度和发展水平不一;空间上,呈现出不均衡态势,湖北省、安徽省、湖南省和江西省旅游高质量发展水平优势明显;河南省、山西省旅游高质量发展水平状况较差。各省份旅游高质量发展主要受创新水平、产业协同、开放发展的影响较大。因此,需要加大旅游产业创新投入,促进区域内外协调发展,提升全域旅游开放共享品质,推动中部六省旅游高质量发展。
