AUTOMATIC HEIGHT EXTRACTION FROM ERS-1 SAR IMAGRY
Zway-Gen Twu , IJ. Dowman
University College London
United Kingdom
Commission II, Working Group 4
KEY WORDS: SAR, DEM Accuracy, Range Error, Intersection Angles
ABSTRACT
Various aspects of stereo height determinations from ERS-1 SAR imagery are described in this paper. A pyramidal stereo
matching algorithm is applied on an overlapping stereo pair of PRI and RTM imagery. The factors that influence the DEM
accuracy are analysed on four different seed points sets. These factors include the ways to select the seed points and the
geometric constraint conditions for SAR intersection. With this standard approach of stereo matching an accuracy of 78m
can be achieved for a DEM. It is shown that the accuracy of the DEM is closely related to the range errors and hence the
intersection angles of the SAR data and that if this error can be controlled a much better DEM accuracy can be obtained.
Experimental results produce a rmse of about 17 m for four different data sets.
1. INTRODUCTION
It is of interest today to study the creation of the Digital
Elevation Model (DEM) created from the Synthetic
Aperture Radar (SAR) for it can provide DEMs in areas
which are not easily accessible to other optical sensors.
In this field of research, previous work is mainly focused
on SIR-B. In particular, Leberl and his group have
written many papers to discuss the subject of stereo
matching (Leberl,1986a), (Leberl,1986b), and Mercer,
(1995) has reported on the use of stereo airborne SAR.
But not many papers have been published regarding the
DEM derivation from ERS-1 SAR. Compared with SIR-
B, ERS-1 gives more accurate orbit header information,
thus it should create a better DEM.
An alternative method of creating DEMs from SAR data
insinterferometry. Stereo. SAR is seen as
complememtary to IFSAR and can be used where
interferometry can not be applied. Work has not yet
been carried out to analyse the best condition for
implementation of stereo SAR.
In UCL, the work on the ERS-1 SAR has been undertaken
for a number of years (Dowman et al.,1992a) (Dowman et
al., 1993) and useful results have ben obtained . The
purpose of this paper is to report on an investigation
into the production of DEMs from stereoscopic ERS-1
SAR data. In this paper, the pyramidal matching
algorithm is introduced and a new strategy is proposed to
increase the DEM accuracy tremendously.
2 PYRAMIDAL STEREO MATCHING
Compared with conventional optical imagery, SAR has
poor image quality which is affected by layover, noise,
and speckle. Thus to stereomatch SAR, there are many
problems encountered. To overcome these problems in
UCL, a new approach is proposed to implement a coarse
to fine pyramidal method. This pyramidal matching is
called CHEOPS [named after the Great Pyramid of Cheops
at Gizza near Cairo] (Denos,1992). The CHEOPS
algorithm is capable of automatically generating the
shell scripts required to match both SAR and other forms
of imagery. It does this by interpreting a script
describing the topology of image pyramids written in a
simple language called PDL (Pyramid Description
Language) and then converting this script into an
equivalent set of executable UNIX shell scripts. In this
paper, the PDL file is defined to use the Otto-Chau stereo
matcher for each tier. The Otto-Chau stereo matcher is an
area-based patch correlation technique which
incorporates the Gruen's Adaptive Least Squares
Correlation and a sheet growing algorithm. This stereo
matcher performed very well in the SPOT imagery (day
and Muller , 1989). The detail of this stereo matcher can
be found in (Otto and Chau,1989). For the seed points,
the CHEOPS uses the random seed points generated in the
first tier of image pyramid. Some research at UCL takes
advantage of CHEOPS in dealing with the matching
problems in SAR image. Dowman et al., (1992b) first
applied CHEOPS on ERS-1 SAR data with different modes
and different angles combination. (Denos, 1991)
implement the CHEOPS on the NASA Seasat satellite
images of Death Valley, and tried 9 tiers achieve
coverage of 81% over 1024 by 1024 imagery.
3. INTERSECTION
The intersection of ERS-1 SAR in this paper is the
analytic approach, proposed by Clark to geocode the
SIR-B imagery in her Ph.D. thesis (Clark,1991). The
analytic approach primarily utilises two Doppler
equations (1) (2) and two range equations (3) (4) to
obtain the solution.
