Abstract
Sonar three dimensional data are represented by a two dimensional image. Pixels of the two dimensional image are emphasized if the if the three dimensional data associated with the pixel differ by more than a criterion from the three dimensional data associated with neighboring pixels.
Claims19
A method of presenting sonar imaging data, comprising:
- a) receiving three dimensional sonar imaging data;
- then
- b) constructing a two dimensional image from the three dimensional imaging data, the two dimensional image comprising pixels arranged as an array, wherein each pixel conveys information;
- c) associating a particular change in the three dimensional imaging data with a particular pixel in the two dimensional image;
- then
- d) if a particular change in the three dimensional sonar imaging data is greater than a criterion, emphasizing the associated particular pixel in the two dimensional image.

- b) constructing a two dimensional image from the three dimensional imaging data, the two dimensional image comprising pixels arranged as an array, wherein each pixel conveys information, wherein the two dimensional image comprises an image in a Cartesian coordinate system having a first and a second horizontal axis and a vertical axis,
- c) associating a particular change in the three dimensional imaging data with a particular pixel in the two dimensional image;
- then
- d) if a particular change in the three dimensional sonar imaging data is greater than a criterion, emphasizing the associated particular pixels in the two dimensional image.

A method of presenting sonar imaging data, comprising:
- a) projecting a sound wave into a sound wave transmitting medium;
- b)receiving sound waves reflected from one or more objects in the sound wave transmitting medium, each of the one or more objects having a defined three dimensional location in the in the sound wave transmitting medium;
- c) transforming the reflected sound waves into electrical signals, the electrical signals comprising the sonar imaging data;
- d) analyzing the electrical signals to record at least the three dimensional locations of the one or more objects, wherein in the electrical signals are analyzed by a processor
- e) constructing a two dimensional image from the three dimensional imaging data, the two dimensional image comprising pixels arranged as an array, wherein each pixel conveys information;
- f) associating a particular change in the three dimensional imaging data with a particular pixel in the two dimensional image;
- then
- g) if a particular change in the three dimensional sonar imaging data is greater than a criterion, emphasizing the associated particular pixel in the two dimensional image.
