Abstract
Method and apparatus for producing an image containing depth information is provided. The method detects radiation emanating from a scene and forms at least two images of the scene at different planes. Each image contains a set of intensity data values. A variation of the data values is obtained so that two sets of intensity variances are obtained from the data values, and the intensity variance data is processed to obtain depth information. The depth information is coded so as to identify different depth information in the image data.
Claims28
A method of producing an image containing depth information, comprising:
- detecting a radiation wavefield emanating from the scene and taking at least two images of the scene at different planes relative to the scene to produce a first image comprised of a first set of intensity data values and a second image comprised of a second set of intensity data values;
- determining an intensity variation of data values in the first set of data values relative to other data values in the first set of data values to produce a first set of intensity variances, and determining an intensity variation of data values in the second set of values relative to other data values in the second set of values to produce a second set of intensity variance data;
- processing the first and second sets of intensity variance data to obtain image data of the scene containing depth information;
- and
- coding the image data which have the same depth information with a code reference to identify the different depth information in the image data.
An apparatus for producing an image containing depth information comprising:
- a camera for detecting a radiation wavefield emanating from a scene and taking at least two images of the scene at different planes relative to the scene to produce a first set of intensity data values and a second set of intensity data values;
- a processor for determining an intensity variation of data values in the first set of data values compared to other data values in the first set of data values to produce a first set of variance data values, and for determining a variance of one data value in the second set of data values compared to other data values in the second set of data values to produce a second set of variance data values;
- the processor also being for processing the first and second variance data values to produce image data of the scene containing depth information;
- and
- the processor also being for coding parts of the image which have the same depth information with a code reference to identify the different depth information in the image.
