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.

f4-sensors-12-02935: Image acquisition for camera interior orientation.

Mentions: A good option in camera calibration is to use the approach described for example by Heikkila and Silven [26], or Zhang [27], which is a mixture of photogrammetric calibration and self-calibration through the use of a flat pattern as a calibration object. In doing so, the benefits of the photogrammetric method, jointly with a greater level of simplicity and speed of operation can be explored. For each camera several images must be obtained, from different angles, of an object with well defined points that must lie in a plane pattern like the one shown in Figure 4.
