bfl - particle filter
Hello,
I'm trying to implement a particle filter using the BFL library from Orocos.
My problem is that my measurement system is multi-modal and in some cases non-analytical, with up to 30 measurements. For some measurements I have and expected value of 0, but for most of them I just know that they should be < 0, but I can't be sure in advance of the exact value. So, it s a bit different from the examples given in BFL website, or in the one from ROS, because they always know the value of the measurement they expect and then use a gaussian distribution to define to probability of this measurement.
I came up with the idea of applying every measurement value I get to a function that gives me an ouput between 0 and 1, and then multiply all these values into a final number (also between 0 and 1) that would be my probability for that measurement.
I'm not sure if this idea has any sense in for the measurement model. If not, can you suggest any way to handle this?
Thank very much!
