Camera Arrangement in Visual 3D Systems using Iso-disparity Model to Enhance Depth Estimation Accuracy
In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...
متن کاملSimultaneous Motion, Depth And Slope Estimation With A Camera-Grid
Standard optical flow methods are very successful for displacement estimation in image sequences using a brightness change constraint equation (BCCE). Recently a multi-camera generalization of the brightness constancy model has been proposed in [22] and tested for several special cases. The complete, unrestricted model has not been investigated yet. This paper bridges this gap and gives additio...
متن کاملVehicle Motion Estimation Using an Infrared Camera
This paper is concerned with vehicle motion estimation. The problem is formulated as a sensor fusion problem, where the vehicle motion is estimated based on the information from a far infrared camera, inertial sensors and the vehicle speed. This information is already present in premium cars. This work is concerned with the off-line situation and the approach taken is to formulate the problem a...
متن کاملStable Camera Motion Estimation Using Convex Programming
We study the inverse problem of estimating n locations t1, t2, . . . , tn (up to global scale, translation and negation) in R from noisy measurements of a subset of the (unsigned) pairwise lines that connect them, that is, from noisy measurements of ± ti−tj ‖ti−tj‖2 for some pairs (i, j) (where the signs are unknown). This problem is at the core of the structure from motion (SfM) problem in com...
متن کاملCamera Motion Estimation Using Particle Filters
In this paper a novel algorithm for estimating the parametric form of the camera motion is proposed. A novel stochastic vector field model is presented which can handle smooth motion patterns derived from long periods of stable camera movement and also can cope with rapid motion changes and periods where camera remains still. A set of rules for robust and online updating of the model parameters...
