运用激光雷达扫描技术进行停车位调查OACSTPCD

The basic spatial data of urban parking space resources are generally obtained by traditional manual measurement and survey,but this method involve heavy workload,low efficiency,untraceable survey results and hidden safety risks in road measurement.In order to solve these problems,taking Nankai District of Tianjin City for example,we used the vehicle and ground laser radar scanning technologies to investigate and collect all kinds of urban parking resources,and extracted the information of all kinds of parking spaces and spaces under bridges by manual and automatic extraction technologies.After data verification,we corrected all kinds of current parking resources,and quickly obtained the basic information of all kinds of urban parking resources.Using lidar scanning technology to survey parking space can break through the traditional operation mode,greatly improve the speed and accuracy of survey,and ensure the safety of personnel and data traceability,which can provide a new technical scheme for the current situation investigation of urban parking space resources.
