3D Target-Oriented Reverse Time Datuming
نویسندگان
چکیده
Reverse time migration (RTM) is theoretically more accurate than traditional migration methods because it computes numerical solutions to the complete wave equation. But RTM is computationally expensive especially for 3D data. To overcome this expense, Luo amd Schuster (2004) suggested a bottom-up reverse time datuming (RTD) method that promised to significantly decrease the computational time for obtaining RTM images. Here we implement this idea for imaging of 3D synthetic data. The preliminary results indicate that the target-oriented RTD can reveal deep structures below the datum with less calculation effort than the full volume RTM.

The Forward Operator and Its Conjugatea
We present a phase shift datuming and migration algorithm for the data acquired on a nonnat surface. First of all, we formulate the exploding reeector modeling scheme for a nonnat recording surface. Then, the migration scheme is found as the conjugate operator of the modeling operator. In order to get the correct migration and datuming operators, the forward modeling must be physically reasonab...

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...
متن کاملFolding Arbitrary 3D Shapes with Space Filling Chain Robots: Reverse Explosion Approach to Folding Sequence Design
We propose a method for arbitrary 3D shape formation by folding chains of hinged polyhedra. This paper presents an algorithm that finds a folding trajectory from an unfolded chain to a target folded chain in a Hamiltonian path configuration. The algorithm is based on the observation that unfolding is generally easier than folding. We can find an unfolding trajectory by applying a radial force t...

The psychological arrow of time refers to our experience of the relentless forward temporal progression of all natural processes. To investigate whether and how time’s arrow is mentally coded in individual everyday events, a relatedness judgment task was used. The items each consisted of a verb (probe) and an adjective or participle (target). The temporal orientation between probe and target wa...
متن کاملHypergraph-oriented 3D reconstruction, interpretation and analysis of air flows
The paper introduces a new air flow analysis approach based on Particle Tracking Velocimetry (PTV). One of the special features of the proposed method is that after the tracer particles are detected, matching and tracking are jointly conducted. To this end, we introduce an interpretation module based on a directed hypergraph for 3D curve reconstruction. At first the 2D inter-frame locations are...
