Vehicle detection and vehicle tracking

[maktubcq52]

Hi all,

I'm trying to construct a vision-based vehicle detection and tracking system on LabVIEW.

I've searched some method to implement the system:

(1)Using pattern/geometric matching function 

     (The matching mode of pattern matching function seems can't search scaled target;however, geometric matching function can do.

      I have tried to combine them,but failed..and I also wonder that if the pattern matching function can achieve vehicle detection and   tracking through camera on moving vehicle.)

(2)Use classification toolkit to create a custom classifier

    (If I take this method, how can I extract the feature?)

I'm a newer to LaVIEW,please give me some idea or example,or if there is any other method that can help me to do the work.

Thank you:)

                                                                                                                                                                                              Regards,

                                                                                                                                                                                              Linda

Hello Linda

What actually you want to do in Vehicle detection and vehicle tracking???

are you trying to do vehicle licnese plate recognition??

If yes then you can use OCR and that you can find in The Vision Development Module .You can find this by going to the LabVIEW Help >> Find Examples >> Toolkits and Modules >> Vision

Hope it will help you

Thank you for your replying!

My objective is to build a vision-based collision avoidance system or a driving assistance system.

Moreover,develop a system that can help vehicle driving itself if possible.

To do so, I think vehicle detection and tracking is the first step that should be done.

Vehicle licnese plate recognition will be one of the function in the system,thanks for the idea!

Is there any other way to help me build the system?

I think this topic closely  relates to object detection,movement detection and tracking

so for this you can use NI vision acquisition and NI vision assistant to get started...

Hello Linda.

If you are in Taiwan, I recommend to download this exercise.

Hi Linda,

My suggestion is break this objective into more specific tasks so you can conquer them step by step. For exampe, to do vehicle tracking, what you need to first is "motion tracking." NI implements some algorithms, such as Horn-Schunck and Lucas-Kanadeon, in Vision Development Module. You might want to check how they works first, use them in a  simplified case, then put them into your vehicle detection system.

Thanks,

Phil
