Method and device for adaptive filtering of three-dimensional image data

摘要

The device has data-and-signal processing unit including a convolving unit for filtering output signals. An imaging region adjacent to the output signals is charged with the convolving unit, and the data-and signal processing unit is arranged such that the filtering process is carried out with the convolving unit when a gray value representing the output signals of the image region exceeds a threshold value. The data-and-signal processing unit is arranged, so that calculation of three-dimensional object coordinates is enabled to output signals filtered by the convolving unit. An independent claim is also included for a method for determining three-dimensional object coordinates using a sensor.
