COMPARISON OF DIGITAL SURFACE MODELS FOR SNOW DEPTH MAPPING WITH UAV AND AERIAL CAMERAS
snow height dense point cloud digital surface model aerial camera
2016/11/30
Photogrammetric workflows for aerial images have improved over the last years in a typically black-box fashion. Most parameters for building dense point cloud are either excessive or not explained and...
KINECT V2 AND RGB STEREO CAMERAS INTEGRATION FOR DEPTH MAP ENHANCEMENT
3D modelling real-time range cameras RGB stereo cameras sensor integration
2016/11/11
Today range cameras are widespread low-cost sensors based on two different principles of operation: we can distinguish between Structured Light (SL) range cameras (Kinect v1, Structure Sensor, ...) an...
TOWARDS THE INFLUENCE OF A CAR WINDSHIELD ON DEPTH CALCULATION WITH A STEREO CAMERA SYSTEM
Stereo camera depth calculation camera calibration bundle adjustment statistical test
2016/11/11
Stereo camera systems in cars are often used to estimate the distance of other road users from the car. This information is important to improve road safety. Such camera systems are typically mounted ...
BOUNDARY DEPTH INFORMATION USING HOPFIELD NEURAL NETWORK
Boundary Stereo Matching Depth Information Optimization Discontinuity Hopfield Neural Network
2016/11/11
Depth information is widely used for representation, reconstruction and modeling of 3D scene. Generally two kinds of methods can obtain the depth information. One is to use the distance cues from the ...
AUTOMATED MOSAICKING OF MULTIPLE 3D POINT CLOUDS GENERATED FROM A DEPTH CAMERA
Depth Camera Point Cloud Mosaicking Tiepoint Similarity transformation
2016/7/27
In this paper, we propose a method for automated mosaicking of multiple 3D point clouds generated from a depth camera. A depth camera generates depth data by using ToF (Time of Flight) method and inte...
