Under vehicle perception for high level safety measures using a catadioptric camera system [PDF]
In recent years, under vehicle surveillance and the classification of the vehicles become an indispensable task that must be achieved for security measures in certain areas such as shopping centers, government buildings, army camps etc.

Evolutionary Based Autocalibration from the Fundamental Matrix
We describe a new method of achieving autocalibration that uses a stochastic optimization approach taken from the field of evolutionary computing and we perform a number of experiments on standardized data sets that show the effectiveness of the ...

Pose Invariant Gait Analysis And Reconstruction [PDF]
One of the unique advantages of human gait is that it can be perceived from a distance. A varied range of research has been undertaken within the field of gait recognition.

Autocalibration of Cameras with Known Pixel Shape [PDF]
We present new algorithms for the recovery of the Euclidean structure from a projective calibration of a set of cameras of known pixel shape but otherwise arbitrarily varying intrinsic and extrinsic parameters. The algorithms have a geometrical motivation based on the properties of the set of lines intersecting the absolute conic ...

Auto-calibration via the absolute quadric and scene constraints
A scheme is described for incorporation of scene constraints into the structure from motion problem. Specifically, the absolute quadric is recovered with constraints imposed by orthogonal scene planes. The scheme involves a number of steps.

The paper addresses two problems related to 3D camera calibration using a single mono-plane calibration target with circular control marks. The first problem is how to compute accurately the locations of the features (ellipses) in images of the target ...

Autocalibration itérative de caméras à partir de structures planes [PDF]
National audienceIn this paper we present an iterative algorithm for camera autocalibration from five or more views of an unknow planar scene. Although our method work provided five views, we aim the particular case of "real time video" autocalibration ...

Continuous pose estimation for stereo vision based on UV disparity applied to visual odometry in urban environments [PDF]
: :This paper presents an autocalibration method to determine the pose of a stereo vision system based on knowing the geometry of the ground in front of the cameras. This pose changes considerably while the vehicle is driven, therefore it is good to know
