Street-parking vehicles in urban areas are causing various traffic problems, however, have been counted manually in the traffic census, including counting error. We propose two auto-detection methods; one is based on an epipolar-plane image analysis, using a line-scan camera, and the other is based on three-dimensional restoration, using a scanning laser range sensor. Both methods achieve high ...

A high precision epipolar line restoration algorithm based on Multipopulation Cooperative PSO (MCPSO) is proposed in this paper. It adopts Harris operator to extract corner point and finishes gray cross -correlation matching. Firstly, the fundamental matrix initial value between matches in two images is calculated by 8 pairs matches algorithm. And then the optimal value of this matrix is gotten...

This work investigates the propagation of errors from the camera motion to the epipolar constraint. A relation between the perturbation of the motion parameters and the error in the epipolar constraint is derived. Based on this relation, the sensitivity of the motion parameters to the epipolar constraint is characterised, and a constraint on the allowed perturbation in a motion parameter in res...

We introduce a new class of panoramic images, called polycentric panoramic images, which is a generalization from more specific classes such as single-center, multiple-center, or concentric panoramic images. This paper focuses on the derivation of an epipolar curve equation for polycentric panoramic images. The epipolar curve equation derived provides a unified approach for the epipolar geometr...

AbstractWe address multiview stereo (MVS), an important 3D vision task that reconstructs a model such as dense point cloud from multiple calibrated images. We propose CER-MVS (Cascaded Epipolar RAFT Multiview Stereo), new approach based on the (Recurrent All-Pairs Field Transforms) architecture developed for optical flow. introduces five changes to RAFT: epipolar cost volumes, volume cascading,...

The view lines associated with a family of proole curves of the projection of a surface onto the retina of a moving camera deenes a multi-valued vector eld on the surface. The integral curves of this eld are called epipolar curves and together with a parametrization of the prooles provide a parametrization of regions of the surface. We present an investigation of epipolar curves on the object s...

The af ne fundamental matrix FA represents the epipolar geometry in the case that the two camera projections are af ne [2]. The problem we address is estimating FA given a pair of corresponding ellipses. This is a minimal con guration for the problem, in a similar manner to the 4 point case. We will start with a counting argument and then derive the solution. FA has four degrees of freedom (dof...

This paper presents a new approach to matching and segmenting multiple rigid motions using epipolar constraint. Epipolar geometry underlying the motion images are rst recovered, and the epipolar equations are used to reduce search for correspondence from 2-dimensional to 1-dimensional, thus resolving the \aper-ture problem". Segmentation of image into dierent motions is simultaneous. Experiment...
