SLAM is a very popular research stream in computer vision and robotics nowadays. For more effective SLAM implementation it is necessary to have reliable information about the environment, also the data should be aligned and scaled according to the real world coordinate system. Monocular SLAM research is an attractive sub-stream, because of the low equipment cost, size and weight. In this paper ...

Accurate position and orientation data are the bases for successful navigation. In this paper, we design and analyze the micro-navigation satellite network that share orientation information among the satellite network. Satellites use GPS, IMU and lasers to align with each other, transferring and sharing the accurate absolute and relative orientation information. Our design includes a GPS and I...

Motion tracking based on commercial inertial measurements units (IMUs) has been widely studied in the latter years as it is a cost-effective enabling technology for those applications in which motion tracking based on optical technologies is unsuitable. This measurement method has a high impact in human performance assessment and human-robot interaction. IMU motion tracking systems are indeed s...

This paper develops and experimentally validates a 3D-printed snake robot prototype. Its structure is designed to allocate limited room for each functional module (including an external power module, battery power module, the wireless control and transmission module and some detective sensors), so as to ensure the snake robot works in different environments. In order to control and track the sn...

In this paper, we present an analysis to identify a sensor location for an inertial measurement unit (IMU) on the body of a skier and propose the best location to capture turn motions for training. We also validate the manner in which the data from the IMU sensor on the proposed location can characterize ski turns and performance with a series of statistical analyses, including a comparison wit...

Direct orientation of laser systems has been widely used for airborne laser sensors but not with the terrestrial laser systems. The usual way to operate a terrestrial laser is by scanning a scene while the sensor remains static. In order to cover the whole scene, different scans can be combined by matching several common points, finally the orientation of the scene is performed by identifying a...

Generating a georeferenced mosaic map from unmanned aerial vehicle (UAV) imagery is a challenging task. Direct and indirect georeferencing methods may fail to generate an accurate mosaic map due to the erroneous exterior orientation parameters stored in the inertial measurement unit (IMU), erroneous global positioning system (GPS) data, and difficulty in locating ground control points (GCPs) or...

LiDAR systems have become a popular technology, which provides fast and accurate acquisition of object space surface models. The process for correcting the LiDAR data, which is distorted by systematic errors, is accomplished either through strip adjustment or LiDAR system calibration. The strip adjustment reduces or eliminates the discrepancies between overlapping strips using the point cloud c...
