Differential Analysis of Two Model-Based Vehicle Tracking Approaches
نویسندگان
چکیده
An experimental comparison of ‘Edge-Element Association (EEA)’ and ‘Marginalized Contour (MCo)’ approaches for 3D modelbased vehicle tracking in traffic scenes is complicated by the different shape and motion models with which they have been implemented originally. It is shown that the steering-angle motion model originally associated with EEA allows more robust tracking than the angular-velocity motion model originally associated with MCo. Details of the shape models can also make a difference, depending on the resolution of the images. Performance differences due to the choice of motion and shape model can outweigh the differences due to the choice of the tracking algorithm. Tracking failures of the two approaches, however, usually do not happen at the same frames, which can lead to insights into the relative strengths and weaknesses of the two approaches.

Optimum sliding mode controller design based on skyhook model for nonlinear vehicle vibration model
In this paper a new type of multi-objective differential evolution employing dynamically tunable mutation factor is used to optimally design non-linear vehicle model. In this way, non-dominated sorting algorithm with crowding distance criterion are combined to fuziified mutation differential evolution to construct multi-objective algorithm to solve the problem. In order to achieve fuzzified mut...

In cruise control systems, the performance of the controller is important. Hence, in order to have accurate results, the nonlinear behavior of a vehicle model should also be considered. In this article, a vehicle with a nonlinear model is controlled by using a nonlinear method. The nonlinear term of the model is the generated torque of engine, which is a polynomial equation. In addition, feedba...
متن کاملThe Development of Maximum Likelihood Estimation Approaches for Adaptive Estimation of Free Speed and Critical Density in Vehicle Freeways
The performance of many traffic control strategies depends on how much the traffic flow models have been accurately calibrated. One of the most applicable traffic flow model in traffic control and management is LWR or METANET model. Practically, key parameters in LWR model, including free flow speed and critical density, are parameterized using flow and speed measurements gathered by inductive ...
متن کاملPath Tracking Control of Tracked Vehicle on Soft Cohesive Soil
This paper deals with path tracking control of tracked vehicle on extremely soft cohesive soil. The dynamics of tracked vehicle is very complex and nonlinear because of the slippage of vehicle and the soil shearing. For the purpose of control of tracked vehicle we adopted simplified approaches. The vehicle is modeled as single-body vehicle. Two kinds of PD (Proportional-Differential) controller...
