Abstract

A unified calibration method between a DVS and a camera, in which a special calibration board is set up which consists of a calibration grid pattern and LEDs attached to the corners of the calibration grids. The camera finds the corners of calibration grid by capturing the image, and the DVS finds the same corners by detecting the intensity changes of the LEDs at the corners, to establish a unified world coordinate system as a reference coordinate system. After performing the calibration and coordinate system transformations, an extrinsic matrix between the DVS and the camera can be obtained.

Abstract

In at least one embodiment, a system for providing a frequency dependent dynamic leakage for noise cancellation is provided. The system includes a noise cancellation controller and a current limiter. The noise cancellation controller is programmed to perform noise cancellation in a vehicle based on a limited input signal. The current limiter is programmed to receive a reference signal from one of an accelerometer or a loudspeaker and to convert the reference signal from a time domain and into a frequency domain to limit the reference signal. The current limiter is further programmed to generate the limited input signal in response to limiting the reference signal.
