A Fast and Simple Method for Absolute Orientation Estimation Using a Single Vanishing Point

چکیده
Absolute orientation estimation is one of the key steps in computer vision, and n 2D–3D point correspondences can be used to obtain absolute orientation, which known as perspective-n-point problem (PnP). The lowest number three if there no other information, corresponding algorithm called P3P solver. In practice, real scene may consist some geometric e.g., vanishing point. When scenes contain parallel lines, they intersect at points. Hence, reduce increase computational speed, we proposed a fast simple method for using single First, inertial measurement unit (IMU) was rotation camera around Y-axis (i.e., roll angle), could simplify estimation. Then, estimate coarse because it contained direction information both frame world frame. Finally, our non-linear optimization solution refining. experimental results show that compared with several state-of-the-art solvers, had better performance regarding numerical stability, noise sensitivity, speed synthetic data images.

The 3-Point Method: A Fast, Accurate and Robust Solution to Vanishing Point Estimation
Vanishing points can provide information about the 3D world and hence are of great interest for machine vision applications. In this paper, we present a single point perspectivity based method for robust and accurate estimation of Vanishing Points (VPs). It utilizes location of 3 collinear points in image space and their distance ratio in the world frame for VP estimation. We present an algebra...
متن کاملPrecise, Automatic and Fast Method for Vanishing Point Detection
A new approach for vanishing point detection is described. This method is based on the theorem of Thales. The main contribution of this paper is the automatic and simultaneous detection of all vanishing points of the image that consists in detecting circles in a complex cloud of points. This extraction is performed without any prior knowledge of the internal calibration. An analysis of the erro...
متن کاملA fast and simple method for modeling of oil swelling in Co2 injection
In this paper, the role of molecular diffusion in mobilization of waterflood residual oil is examined. A moving mesh method is applied to solve the moving interface problem of residual oil blobs swelling by Co2 diffusion through a blocking water phase. The results of this modeling are compared with experimental results of a 2D glass micromodel experiment. Although, the solution method is applie...
متن کاملLeaf area estimation by a simple and non-destructive method
In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...
