The introduction of the Huff model is of critical significance in many fields, including urban transport, optimal location planning, economics and business analysis. Moreover, parameters calibration is a crucial procedure before using the model. Previous studies have paid much attention to calibrating the spatial interaction model for human mobility research. However, are whole sampling locatio...

Population-based search methods such as evolutionary algorithm, shuffled complex algorithm, simulated annealing and ant colony search are increasing used as automatic calibration methods for a wide range of water and environmental simulation models. However, despite the advances in computer power, it may still be impractical to rely exclusively on computationally expensive (time consuming) simu...

Abstract We present a new calibration method for a structured light surface scanner. The new method uses a model-based calibration, accounting for laser stripe and translation stage alignment and the internal and external camera parameters. The inclusion of non-linear radial distortion in the camera model gives an improvement in the calibration accuracy over a linear model. The method has been ...

This paper is concerned with the calibration of the intrinsic and extrinsic parameters of a X-ray angiographic system for 3D reconstruction of coronary vessel centerlines. We discuss whether the isocentric model is an accurate model for the movement of the C-arm, and analyse the assumptions made by this model. We propose a methodology which takes into account these facts and we propose for each...

We present a fully integrated active vision system for interpreting dynamic scenes. We argue that even if the ego-motion of the mobile vision system is known, a single view camera calibration cannot adequately support scene model acquisition and maintenance. It is shown that stable camera/grabber chain calibration can be achieved using a multi-view calibration process. With such calibration, a ...
