“…Thus, the on-orbit calibration geometric parameters are performed in many satellites using data of experimental field (Wolfgang Kornus et al, 2000;Grodecki et al, 2002;Gruen et al, 2007;Breton et al, 2002;Srinivasan et al, 2008;Jiang Yonghua et al, 2013). The self-calibration using additional parameters and the aerial triangulation bundle adjustment are two methods to calibrate the geometric parameters on-orbit.…”

ABSTRACT:The Tian-Hui 1 (TH-1) is the first stereo mapping transmission satellite in China, and the primary mission goal of the satellite is for topographic mapping at 1:50,000 scale without Ground Control Points (GCPs). 1st, 2nd and 3rd satellite of TH-1 was launched on August 24, 2010, May 6, 2012 and October 26, 2015. In TH-1 satellite, many payloads are put on a small satellite platform, which has a low cost. The optical camera of TH-1 includes Line-Matrix CCD (LMCCD) camera, high resolution camera and multispectral camera with 60 km ground swath width. To get high geometric accuracy without GCPs, the on-orbit calibration camera parameters and the Equivalent Frame Photo (EFP) Multi-functional bundle adjustment are proposed and realized in ground image processing of TH-1. In order to evaluate the location accuracy of TH-1, some testing fields are established. All GCPs of testing fields are measured by GPS. The GCPs are not participated the EFP Multi-functional bundle adjustment, and are only as Check Points (CPs) to evaluate the location accuracy. The evaluation of 1st satellite is shown: the horizontal accuracy is 10.3 m (RMSE) and the vertical accuracy is 5.7 m (RMSE) without GCPs, which can satisfy for topographic mapping at 1:50,000 scale. The overviews of TH-1 satellite are described in this paper: First, the system overview is introduced, including mission and optical camera of TH-1. Then, the on-orbit calibration camera parameters using LMCCD image and the EFP Multi-functional bundle adjustment are presented. Finally, the location performance is analysed without GCPs and with different number of GCPs. In addition, the products of TH-1 are introduced.

“…A number of research work and applications for the photogrammetric adjustment of 3-line-imagery have been conducted (Chen et al, 2001;Lee et al, 2000;Ebner et al, 1991 andFraser and Shao, 1996;Frisch et al, 1998;Ebner et al, 1999;Kornus et al, 2000). The DGR (Direct GeoReference) method was adopted in our approach since on-board high precision GPS/IMU data could be used for PRISM imagery orientation.…”

“…Different from SPOT-1 and SPOT-2 launched in 1990, which are collecting stereo images by side-looking push-broom mode and have certain disadvantages, for example different atmospheric conditions can prevail on different passes, thus degrading the stereo images, MOMS (Modular Optoelectronic Multispectral Stereo Scanner)-02/D2, MEOSS (Monocular Electro-Optical Stereo Scanner), HRSC (High Resolution Stereo Cameras) and IKONOS-I of SpaceImaging collect digital along-track stereoscopic imagery using a three-line camera (Ebner et al, 1991 andFraser and Shao, 1996;Frisch et al, 1998;Ebner et al, 1999;Kornus et al, 2000). PRISM (Figure 1) of ALOS to be launched in 2004 has three radiometers for Forward, Nadir and Backward viewing to collect along-track stereoscopic imagery at 2.5m ground resolution on 691.65km orbit altitude above equator for 1:25,000 mapping.…”

For natural landscape, area-based matching can be successfully applied because the elevation is undulating rather gently. On the other hands, urban areas with the mixture of artificial structures such as buildings and natural landscape, where the elevation tends to have steeper changes, conventional area-based matching may not be successful. Many computer vision papers demonstrated matching methods based on features such as edge and regions extracted from images have much better performance for artificial structures. 2.5 m ground resolution of PRISM, however, may not be enough to extract detailed features enough to represent artificial structures. This may suggest the combination of area-based and feature-based matching approach can be more appropriate for ALOS PRISM data. This paper presents the results of experiments on the combination of the two approaches using simulated PRISM image generated from air-borne image sensor, TLS (Three Line Scanner).

“…The main objective of their study was to orthorectify images and register on the master image. Kornus et al (2000) gained the image registration and image matching techniques for calibration of MOMS-2P's images. Their study focused on obtaining the shift between channels MS1, MS2, MS3, MS3, and the shift between channels MS2, MS3, MS4, and finally shift to channel HR5A.…”

The effect of Digital Earth on our life is vital. Developing and updating Geospatial data in Digital Earth is also essential. This paper presents the application of a new approach of image registration in Digital Earth. The approach was developed based on registering a mono photograph on a master 3D model. The result is a 3D vector model, which can be broadly applied in visualisation, mapping, geographic information system (GIS), planning, change detection, as well as Digital Earth. The approach does not require parameters of correction for transformation. The accuracy of the output depends on the accuracy of the master data. This approach is very versatile and able to register any image on the digital elevation model, digital surface model and topographic 3D model.
