Abstract

The present invention adjusts images received from plural cameras that are oriented to plural directions and combines the images with distance information. Thereafter, the circumstantial environment is visualized based on a moving object using an augmented reality technique to provide to a user. Specifically, the present invention adjusts images in plural directions and adds the distance information to improve the accuracy and uses a visualization method that displays the images with respect to the moving object.

Claims

1. An external environment visualization apparatus, comprising:

a multiple image capturing unit configured to capture multiple images regarding an external environment;

a distance measuring unit configured to measure a distance to at least one object included in an image when at least one image included in the multiple images is captured;

a distance reflecting unit configured to reflect the distance to an image whose distance is measured; and

a multiple image displaying unit configured to display the multiple images based on the image whose distance is reflected.

2. The apparatus of claim 1, wherein the multiple image capturing unit and the distance measuring unit are mounted in a moving object which is a reference for defining the external environment or the external environment visualization apparatus is mounted in the moving object.

3. The apparatus of claim 1, further comprising:

an image compensating unit configured to compensate the distortion of the captured images using a reference image; and

an image adjusting unit configured to adjust the distortion-compensated images.

4. The apparatus of claim 3, wherein the multiple image displaying unit displays the multiple images based on the adjusted images.

5. The apparatus of claim 1, wherein the distance measuring unit measures the distance whenever the respective images that form the multiple images are captured.

6. The apparatus of claim 1, wherein the multiple image capturing unit includes vision sensors that are oriented to different locations and whose orientation positions or orientation angles can be changed.

7. An external environment visualization method, comprising:

a multiple image capturing step of capturing multiple images regarding an external environment;

a distance measuring step of measuring a distance to at least one object included in an image when at least one image included in the multiple images is captured;

a distance reflecting step of reflecting the distance to an image whose distance is measured; and

a multiple image displaying step of displaying the multiple images based on the image whose distance is reflected.

8. The method of claim 7, further comprising:

an image compensating step of compensating the distortion of the captured images using a reference image;

and an image adjusting step of adjusting the distortion-compensated images.

9. The method of claim 8, wherein the multiple image displaying step displays the multiple images based on the adjusted images.

10. The method of claim 7, wherein the distance measuring step measures the distance whenever the respective images that form the multiple images are captured.

11. The method of claim 7, wherein the multiple image capturing step uses vision sensors that are oriented to different locations and whose orientation positions or orientation angles can be changed.
