Sensor integration in a low cost land mobile mapping system.

Madeira S, Gonçalves JA, Bastos L - Sensors (Basel) (2012)

Bottom Line: Mobile mapping is a multidisciplinary technique which requires several dedicated equipment, calibration procedures that must be as rigorous as possible, time synchronization of all acquired data and software for data processing and extraction of additional information.To decrease the cost and complexity of Mobile Mapping Systems (MMS), the use of less expensive sensors and the simplification of procedures for calibration and data acquisition are mandatory features.The results discussed here show that this goal has been achieved.

ABSTRACT
Mobile mapping is a multidisciplinary technique which requires several dedicated equipment, calibration procedures that must be as rigorous as possible, time synchronization of all acquired data and software for data processing and extraction of additional information. To decrease the cost and complexity of Mobile Mapping Systems (MMS), the use of less expensive sensors and the simplification of procedures for calibration and data acquisition are mandatory features. This article refers to the use of MMS technology, focusing on the main aspects that need to be addressed to guarantee proper data acquisition and describing the way those aspects were handled in a terrestrial MMS developed at the University of Porto. In this case the main aim was to implement a low cost system while maintaining good quality standards of the acquired georeferenced information. The results discussed here show that this goal has been achieved.

Mentions: Besides the relative orientation parameters between remote sensors it is also necessary to obtain the relative orientation between one of them and the DGS referential. It can be assumed that the DGS reference system axes match those of the moving platform and its center coincides with the INS origin or with the phase center of a GNSS receiver. In this case the parameters are called angular and linear offsets. In Figure 6 an example is presented, showing only the XY plane. In this case the DGS centre is the phase centre of a GNSS antenna and the v subscripts stands for “vehicle”, while the c subscripts for “camera”. The linear offsets are the three components of the translational vector T. As the figure is depicted in a horizontal plane only the rotation of the Z camera axis relatively to the DGS can be observed, named the κoffset.
