Abstract
An enhanced vision system (EVS) is integrated with a heads-up display (HUD). The EVS generates image of an external scene. The EVS generates the images without repeatedly generating the images when a mode of the HUD changes. The EVS includes an expanded interface, where inputs from the HUD are used in the internal processing of the EVS. The HUD then displays information in a graphical and alphanumeric format. The information can include an enhanced vision image from the EVS and/or a synthetic vision image from a synthetic vision system (SVS). The enhanced vision image can be merged with a synthetic vision image to provide a combined vision image.
Claims15
An enhanced vision system comprising:
- an image sensor;
- wherein the image sensor is configured to generate an enhanced image;
- a communication interface;
- a memory;
- wherein the memory maintains program instructions;
- and
- one or more processors;
- wherein the one or more processors are configured to execute the program instructions;
- wherein the program instructions cause the one or more processors to:
- receive, via the communication interface, at least a gamma and a brightness signal;
- generate a lookup table based on the at least the gamma and the brightness signal;
- generate a transformed-enhanced image by applying the lookup table to the enhanced image;
- and
- transmit, via the communication interface, at least one of:
- the enhanced image and the lookup table;
- or
- the transformed-enhanced image.
An aircraft comprising:
- a heads-up display;
- and
- an enhanced vision system;
- wherein the heads-up display and the enhanced vision system are communicatively coupled;
- wherein the enhanced vision system comprises:
- an image sensor;
- wherein the image sensor is configured to generate an enhanced image;
- a communication interface;
- a memory;
- wherein the memory maintains program instructions;
- and
- one or more processors;
- wherein the one or more processors are configured to execute the program instructions;
- wherein the program instructions cause the one or more processors to:
- receive, from the heads-up display via the communication interface, at least a gamma and a brightness signal;
- generate a lookup table based on the at least the gamma and the brightness signal;
- generate a transformed-enhanced image by applying the lookup table to the enhanced image;
- and
- transmit, to the heads-up display via the communication interface, at least one of:
- the enhanced image and the lookup table;
- or
- the transformed-enhanced image.
