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: Inertial navigation is a technique that allows the determination of position and orientation of a mobile body in a navigation (fixed) reference frame, by measuring its accelerations and angular velocities. Through successive mathematical integrations with respect to time, we can obtain velocity, position and attitude of the mobile platform. An Inertial Measuring Unit (IMU) contains accelerometers and gyroscopes, that together allow obtaining linear accelerations and angular velocities along three axes in a predefined inertial frame (for detailed information see, for example [16]). As a result, a motion vector for each instant can be obtained (illustrated in Figure 2 as vector M⃗).
