Patent Images
1. A slope monitoring system comprising:
- a radar module that records radar images of a selected slope;
a video module that records visual images of said selected slope;
and data processing means that performs;
coordinate registration to align said radar images and said video images; and
interferometry to produce interference maps indicative of movement of said selected slope from said radar images and/or said video images.

Abstract
A slope monitoring system having a radar and a video camera recording images sequences of the slope. A data processing unit performs coordinate registration to align the radar images and the video images. Interferometry is used to detect movement in the slope by generating interference maps between the images. These are suitably phase maps showing the phase change between a radar image and a reference image. An alarm occurs if a significant movement is detected.

20. A method of identifying a region of a slope prone to failure including the steps of:
-
recording a video image of the slope;
recording a first radar image of the slope;
recording a second radar image of the slope;
calculating an interference map from the first radar image and the second radar image;
performing coordinate registration between the interference map and the video image;
analysing the interference map to identify regions prone to failure;
and using the coordinate registration to identify the region on the slope. - View Dependent Claims (21, 22)
