Abstract

The invention relates to a detection system and method for dynamic positioning precision of a POS (point of sale) system. The detection system comprises a tracking measurement device, a control device, a measurement cooperative target and a time service device, wherein the measurement cooperative target is mounted on a carrier according to placement parameters between the measurement cooperative target and the to-be-detected POS system; the motion state of the carrier where the measurement cooperative target is located is tracked, and data, measured by the tracking measurement device and the POS system, of the carrier where the measurement cooperative target is located are acquired; overall locus and point position comparison is performed on the data measured by the tracking measurement device and the POS system and the dynamic positioning precision of the POS system is determined. The problem of inaccurate detection precision caused by adoption of error estimation and imaging quality analysis in POS system precision detection at present is solved. The system and the method contribute to completion of a dynamic error model of a mobile measurement system, provide a basis for establishment of a unified sensor placement parameter calibration standard, play a role in promoting development of the mobile measurement technology and have important theoretical significance and application value.

Description

technical field [0001] The invention relates to a POS system dynamic positioning accuracy detection system and method, and belongs to the technical field of dynamic positioning accuracy evaluation. Background technique [0002] With the advancement of smart city and digital city construction, the measurement technology for rapid acquisition and processing of geospatial information has attracted widespread attention. Mobile Mapping Systems (MMS), as an efficient means of acquiring urban spatial location data, has become a current research hotspot. [0003] As an important part of the mobile measurement system, the POS system provides real-time spatial position and attitude information, so that the laser point cloud and image data obtained by the mobile measurement system have geographic coordinates. The POS system is an integrated navigation system composed of an inertial measurement unit (Inertial Measurement Unit, IMU) and a global positioning system (Global Navigation Sat...
