Abstract

A method for producing panoramic images whereby a shot is made from a desired shooting position, with the use of a camera having fish eye optics whereby the image is scanned and then digitized, images are transformed into a panoramic image with the use of a computer and software. The digital image is scanned by dividing the image into narrow radial segments, each of which is divided into a number of parts of equal length whereafter each segment part is depicted as a point on a straight line, whereby the grey tint of each segment part is corrected for the modified surface on which it is depicted. Apparatus comprises a camera with fish eye optics and a CCD matrix imager upon which the image to be obtained is projected, obtaining immediately an image in digital form.

Claims

1. A method for producing panoramic images comprising the steps of:

making a surroundings shot from a desired shooting position with a camera having a fish eye optic to obtain a fish eye image;

centering a scanning means onto the center of said obtained fish eye image;

rotatingly scanning said fish eye image by a rotating scanning array of aligned light sensitive elements such that the fish eye image is divided into successive radial parts in a digital form; and

transforming said successive radial parts into a panoramic image with a computer and software.

2. The method according to claim 1, wherein said fish eye image is a photographic image on the center of which a pivoting image device is centered.

3. The method according to claim 1, wherein said panoramic image has an information density of approximately 1.9 megabyte.

4. The method according to claim 1, wherein said panoramic image has an information density of 8.8 megabyte or less.

8. The method according to claim 4 further comprising the step of associating information with said panoramic images and/or said layout by recording said information in said computer along with said panoramic images or said layout.

9. The method according to claim 8, wherein said information is one or more of the set consisting of address, date, time, orientation, compass direction, house numbers and street names.

5. A method for producing panoramic images comprising the steps of:

making a surroundings shot from a desired shooting position with a camera provided with a fish eye optic and an image area provided with a CCD-matrix;

obtaining a fish eye image in digital form with said CCD-matrix; and

transforming said image in digital form into a panoramic image with a computer and software to remove distortions and render said image in a form which can be perceived by the human eye without said distortions.

6. A method for assembling a file of object images from which one or more desired images can be quickly consulted, comprising the steps of:

taking a large number of panoramic images from successive shooting positions with a camera provided with a fish eye optic whereby said shooting positions are chosen such that said images taken from said successive shooting positions partly overlap to obtain fish eye images;

digitizing said fish eye images;

transforming said digitized fish eye images into panoramic images with a computer and software to remove distortions and render said images in a form which can be perceived by the human eye without said distortions;

recording said panoramic transformed digitized fish eye images in a computer;

creating a layout; and

storing said layout in said computer along with said panoramic images recorded in said computer wherein points are indicated on said layout from which said panoramic images were taken, and on which said panoramic images are stored.

7. The method according to claim 6, wherein a part of said panoramic images is displayed as a quadrant.

10. A computerized system for assembling and reviewing a file of panoramic images associated with a layout and additional information such that one or more images can be simply consulted from said file, said system comprising:

a computer including a data storage means;

one or more panoramic images obtained from one or more shooting positions wherein said panoramic images are digitized and transformed with a computer and software to remove distortions and render said images in a form which can be perceived by the human eye without said distortions, whereupon said images are stored in digital form in said computer;

a layout stored in digital form in said computer on which points are indicated from which said one or more panoramic images were made; and

additional information stored in said computer, said additional information providing access to a desired image and whereby said one or more panoramic images can be divided up into arbitrary sections, said sections including quadrants, dependent on a desired viewing direction from a particular shooting position.

11. The system of claim 10, wherein said additional information is one or more of the set consisting of address, date, time, orientation, compass direction, house numbers and street names.
