A process for generating distance images operates by the emission of light pulses and the synchronized time-delayed reception of the reflected light pulses on an image receiving unit with a shutter device connected in front of it. During the reception of a reflected light pulse, the transparency of the shutter device passes through a given time-dependent function and in this manner at least two such modulated reflection images are generated while different transparency functions are used. A color is assigned to each of these images, and the colored images are superimposed to form a false-color-coded distance image.

Process and a system for taking distance images

The camera includes two functionally equivalent line and field scanners, one for issuing a light pulse that will be returned by an object point, and identified by a particular line/field scanning position in both scanners; the second scanner being attuned to recognize the returned light in one scanning raster point only for purposes of correlation. The field scan is realized through a deflecting mirror or in a columnal array the line scans are either solid state or fiber optics.

Range finding camera

A method of using a method for navigating and updating of navigation for aircract under utilization of sensor image processing and reference store data, for purposes of automatic or assisted landing is disclosed.

Method for navigation and updating of navigation for aircraft

A method for navigation and updating of navigation for aircraft uses range image processing and a reference store, segmentizing the range image data are segmentized in order to obtain a particular pattern of type features for purposes of classifying particular types of objects across which the craft flies; extracting particular signature features including localized elevational jumps and determining the position of the craft by correlating a plurality of features and their spatial orientation to each other as extracted with corresponding stored reference information in order to provide a maximum fit that is indicative of deviation of the flight from a flight path as identified by the reference information.

Method of navigation

Optical radar includes a linear transmitter diode array with each diode in the array being individually controllable for transmitting a light pulse on being triggered; and a receiver diode array is positioned in relation to the transmitter array in conjunction with optical imaging means such that a diode of the transmitter array is imaged on the ground on the same area which is seen by a particular diode of the receiver array so that a 1:1 relation is established between a diode providing a particular transmitted light pulse and a diode that can receive said pulse.

Optical radar

A method for aircraft navigation which includes, sensor signal processing with refernce data. The method provides for sensing and range finding the elevational profile underneath the craft. Those elevational data are fed to a segmentizing and type classifying unit whose output in turn is fed to a classifying unit, and that the position of the craft is determined by comparing the segmentized overflight strip with corresponding topographic features in reference information.

Linear method of navigation

Short light pulses are emitted and images of the reflection from objects are received; the receiving is timed and synchronized to obtain partial images corresponding to reflection from particular ranges; the partial images are then combined in a composite range image.

Acquisition of range images

Selecting of particular image lines for composition of range image such that a composition and evaluation of range image is possible in real time actually corresponds to the imaging of a TV or video camera. The image field is scanned column by column and the contents of the column (all lines) are read in parallel. After digitizing the content of the column, a selection logic selects a particular imaging dot within each of the columns. Using the principles of triangulation, the line position of the dot selected is identified by a multibit binary data word is vertical position in representation of the distance from the camera or the light strip source.
