摘要:
Embodiments of the disclosed systems and methods establish quantitative and accurate relationships between system features and system objectives. In one embodiment, the systems and methods are particularly suitable to establish the predictive relationships between system fidelity and training objectives. These systems and methods can combine fidelity values defined by end-users, existing theory and research, or objective performance data from experiments. The predictive relationships defined through these methods can feed a model-based decision support tool that helps predict the impact of fidelity on training effectiveness.

A method and a system for video camera assembly are provided. The video camera assembly includes at least one of a pan mechanism rotatable about a pan axis and a tilt mechanism rotatable about a tilt axis. The pan mechanism includes a pan motor and a pan position encoder. The tilt mechanism includes a tilt motor and a tilt position encoder. A controller is communicatively coupled to at least one of the pan mechanism and the tilt mechanism and is configured to apply a filter to a power drive signal of at least one of the pan motor and the tilt motor based on a determined corresponding rotational speed of the at least one of the pan motor and the tilt motor with the effect of reducing steady state vibrations which degrade the visual and audible qualities of said video camera assembly.

A method for operating a surveillance system includes performing a first portion of an automated visual surveillance tour of a predetermined control area by inducing movement of at least one visual surveillance camera at a first camera tour speed. The method also includes recording at least one first video image frame of the predetermined control area. The method further includes recording at least one second video image frame of the predetermined control area. The method also includes automatically determining whether a region of interest exists within the predetermined control area. The method further includes performing a second portion of the automated visual surveillance tour by shifting the induced movement of the at least one visual surveillance camera to a second camera tour speed. The method also includes automatically dwelling on the region of interest.

A method and system for video camera assembly are provided. The video camera assembly includes at least one of a pan mechanism rotatable about a pan axis and a tilt mechanism rotatable about a tilt axis. The video camera assembly further includes an accelerometer coupled to the at least one of the pan mechanism and the tilt mechanism and a controller communicatively coupled to the at least one of the pan motor and the tilt motor, the controller further communicatively coupled to the accelerometer, and the video camera. The controller is configured to receive acceleration data from the accelerometer, determine an oscillatory displacement of the video camera using the received acceleration data, generate a motor angular modulation signal, and apply the motor angular modulation signal to at least one of the pan motor and the tilt motor to reduce the oscillatory displacement of the video camera.
