Real-Time Code Generation for a Passive Range Estimation Algorithm

Abstract:

Passive range estimation based on tracking features using images 

taken in real-time is a very time consuming task to execute on 

typical computer architecture's. Major modifications to the 

algorithm are required to efficiently use the target hardware 

executing the algorithm. 

Previous work to meet real-time processing needs has focused on the 

following options: 

*  Designing a special hardware architecture to execute the 

algorithm in real-time.

* Designing a parallel computing architecture using available 

processors.

The first option proves to be very expensive and applies only to 

the particular algorithm it is designed for. The second option has 

the advantage of being usable for other implementations but is 

difficult to code effectively, still requires some special purpose 

designs, and is yet to satisfy a need to execute the algorithm in 

real-time. 

An alternative solution is to have a tool that can automatically 

generate executable code that can be executed in real-time on 

available computer hardware. This solves the problem of having to 

design special hardware architecture's, and makes it easy to 

efficiently modify and test.


This technique has commercial applications in the field of robotics 

and automation, automatic landing of aircraft, and aid pilots under 

minimum visibility conditions using infrared (IR) sensors.
