SBIR-STTR Award

For this Phase I effort, Observera, Inc. proposes to develop a model based approach for deriving the parameters of an airborne imaging unit from the images collected during its flight. In order to concentrate Phase I efforts on feasibility and on the difficult problems of (1) developing the sensor model, (2) developing its associated error model, and (3) deriving an approach to correct an initial estimate of the imaging systems parameters, we will make maximum use of GOTS/COTS software for other aspects. For the sensor model, we will use a perspective-projective transformation matrix (PPTM) in homogeneous coordinates. For the error mode, we will analyze the impact of errors in the parameters of the PPTM on the results of the projection of the image to the Earth's surface. The projected image will be orthorectified and registered to a reference image or map. The error analysis will then be used to formulate a method for allocating the corrections derived from the registration back to the parameters of the PPTM.

For this Phase II SBIR effort, Observera, Inc. proposes to implement the model-based approach for determining the x,y,z position; and role, pitch, and yaw of an airborne imaging unit from the images collected during its flight. The approach was developed and tested in the Phase I SBIR effort using data collected from a man aircraft. In Phase II, Observera will integrate the system's custom, commercial, and Government off-the-shelf software with the Governments existing/planned hardware suite. Observera will also provide training and field support related to this system. The system Observera is developing has the potential to be used with various types of sensor data from various sources.
