Recently, studies on the construction of 3D terrain modeling and location accuracy evaluation using UAV have been conducted, but application to coastal areas lacking image matching points has not made in detail yet. In topography survey UAV, ortho-images DSM (Digital Surface Model) data were constructed through imaging ground control point (GCP) surveying ground. case ortho-images, VRS was used...

Recently, a car employs various built-in sensors such as a speedometer, odometer, accelerometer and angular rate sensor for safety and maintenance. These sensory data can be provided in real time through a CAN (Controller Area Network) bus. In addition, image sequences can be provided from various cameras mounted to the car, such as built-in front and around view monitoring cameras. We thus pro...

Abstract. The large field of view and compact structure make fisheye lens cameras an attractive technology for mobile mapping systems visual navigation. Fisheye usually have a equal to or higher than 180°. Lenses that can capture light rays coming from angles larger 180° are known as hyper hemispherical lenses. Some the existing mathematical models be unsuitable those points beyond when perform...

In this paper, we present a method that allows simultaneous surface reconstruction and camera localization from monocular images in static scenes. The novel aspect of the method is its independence from any explicit feature detection schemes. Instead, it uses method similar to intensitybased bundle adjustment. Thus, it is better suited for 3D reconstruction of weakly textured surfaces. A number...

An algorithm that shows how ray divergence in multi-view stereo scene reconstruction can be used towards improving bundle adjustment weighting and conditioning is presented. Starting with a set of feature tracks, ray divergence when attempting to compute scene structure for each track is first obtained. Assuming accurate feature matching, ray divergence reveals mainly camera parameter estimatio...
