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: The remote sensors can be video cameras, laser scanners, etc. The DGS are, usually, associations of Global Navigation Satellite Systems (GNSS) receivers and Inertial Measurement Units (IMU), although other associations of dead reckoning devices that include odometers, inclinometers or digital compasses can also be used. The linkage of absolute positions and orientation parameters (obtained by the DGS) to the data obtained by the remote sensors allows for positional and geometrical information of the observed objects. Figure 1 shows a typical flowchart of the various modules used in a MMS.
