·Upon loading of the image data, Titan photo will use a proprietary algorithm generates a large number of stereo images, and the stereo image pair assigned to the available computing nodes to perform parallel computing, thus reducing the stereo matching process time. According to the multi angle data automatic multiple correlation, can be easily extracted DSM, heading and adjacent to the stereo image pair through multiple correlation method for matching, which is a point-by-point calculation process. Automated algorithms can be obtained from original image every two pixels of the elevation information, finally through the integration of the digital surface model.In addition, the Titan photo system can import and export LAS (LIDAR) format data, therefore on LIDAR DSM and multiple correlation generated DSM mixed.

 

 

·DSM calculation is carried out in real shot in the process of calculation is the most important step, only using the digital surface model can be used for orthophoto real firing correction, to ensure that the image of an arbitrary point on the geometric precision.

2) Semi-automatic Extraction of Digital Terrain Model of DTM
3) Extraction of Digital Terrain Model of DTM
4) Large-scale Production of Real and Traditional Orthophoto
5)Image seamless mosaic and uniform color
·Titan photo realize the orthophoto Image Automatic Mosaic, and has strong uniform color function. For the treatment of large area can be reflected more the system of high efficiency and high quality.
·For traditional orthophotos, system can be of any spectral band combined with high resolution panchromatic image generating fusion.
·Automatic generation algorithm can improve the resolution of multispectral images preserves the spectral information. And Titan photo can be based on image spectrum feature, automatically generate optimal image combination. This means that the fusion algorithm, in the fused image classification does not produce artifacts.

3. The Characteristics of Titan photo
Titan photo is the world's first earth observation data automatic processing system, automation, parallel processing, a variety of imaging compatibility, remote management features in one, representing the current remote sensing image data processing technology development direction.

 

 


Center Server Processing Platform

·In response to the massive image processing
·Multivariate data corresponding to one
·Unified data management and distribution
·Accurate data mosaic
·"Wisdom" model
The Perfect Combination of Software and Hardware System Architecture
·Titan photo is a set of hardware and software combination, rapid production of solution. Using high performance computes (High Performance Computing) cluster and SAN (Storage Area Network storage area network) architecture.
·High performance computing cluster is committed to providing a single computer can not provide a powerful computing capacity and load balancing technology, guarantee, ensure the stable operation of the server.
The main advantages of cluster architecture:
·Scalability: the computer node and the set of cluster system is highly extensible performance.
·High availability: a node in a cluster failure, its task can be passed to other nodes. Prevent a single point of failure.
·High performance: load balancing cluster allows the system to simultaneously access the more users.
·High cost: can use cheap conform to the industry standard hardware structure of the system of high performance.

 

 

Full Support for the Current Mainstream of Various Aerospace Sensor

From the three solutions to the final products such as DSM, DEM, according to plans, processing system automatically assigned tasks, automatic large task into several sub task. Through automated processing, greatly reduce the manual labor, improve working efficiency.
·Titan photo digital products in the production process will produce large amounts of data more than the initial intermediate data and the result data, only has a massive online storage capacity, can guarantee the engineering continuous automatic operation. Titan photos use disk array to achieve massive online storage technology, and periodically on the data backup, the maximum possible to avoid accidents caused by the loss of data, ensure the safety of the data.
The Improvement of Traditional Algorithm and 200 Kinds of Advanced Algorithm

 

 

·Traditional photogrammetric based on each image individually corrected to obtain the orthophoto Image, and then through the mosaic, so that each image parallax minimum. But for Titan photo, Ortho rectification way is just the opposite: Orthophoto above each of the pixels are considered separately, each point is through it in the original image as points combined with it in DSM elevation information to determine. This process is fully automated, is also distributed. It can ensure the ground every point is from the vertical angle (of the high-rise building tilt can be eliminated).
·Titan photo has advanced image processing algorithms and many years of accumulation of technology, which represents the current remote sensing image processing technology to the latest development direction.200 kinds of advanced algorithm: sensor calibration, the original image enhancement (atmospheric correction, correction, ionization) fast multi sensor aerial triangulation, rapid automatic generation and remove connection point, automatic extraction of concentrated DSM, real radio correction and traditional geometric correction, automatically by the DTM to automatic generation of contour, mosaic (orthophoto, elevation image and the second generation damascene), image enhancement (local uniform light, contrast, balance compensation etc.).
·Titan photo through the establishment of image mosaic plug (SGM) on the existing digital orthophoto mosaic images, rapid update. The processing from the reference database to extract all the required parameters, automatically complete bundle adjustment and radiation correction. The mosaic is spectacularly reduced production time, and with the perfect combination of the original data. This plug-in on satellite images and aerial photograph are applicable, and the production environment (including ground receiving station).
