Optical Flow Tracking, Help!

[falconmaster]

We want to use the bottom the pool to track our movements and then compare it to a virtual map of the pool.

1. The pool floor has a patter of markings caused by algae patches and the pool floor.

2. We are assuming a given height for the time being because different distances from the pool floor will result in different velocities. We can add that to the formula after we are able to track our velocities. Different heights will require different adjustments to the pattern tracking algorithm. We can determine this by experimentation

3. We know a mouse uses this type of algorithm to move the arrow on a computer screen, this is the code we are trying to get our hands on. We think if we have this, we will be able to use it to accomplish tracking goal.

4. Basically it is comparing one frame of video to another frame of video and measuring the differences between the two images and calculating the direction, the degree of difference is compared to the known frame rate and this will give us speed.

5. We will use this data of movement to locate where we are in a virtual pool that we will build in our computer. We do know where we start so we should know where we are if this works.

Does this help? Now can you help? Or Do you know someone who can help us get this code?

Thanks in advance!!!!!!
