drawing a map and specifying the coordinates of sensor

[amit1986]

Can we draw a 2d map indicating obstacles and free space.Also points to indicate the location and coordinates of fixed  and moving recievers .I am free to assign coordinates to my fixed sensor based on these coordinates i am trying to calculate the location and coordinate of moving reciever.

anyone its urgent...

Dear Amit1986,

Welcome to the forums.

I have been trying to understand the problem your having and I think your trying to use picture controls? Is that right?

Would you be able to clarify the scenario in which your having these problems?

In addition, what version of LabVIEW are you using and do you have additional toolkits?

My suggestion would be to look on the NICommunity page at examples related to 2D and 3D picture controls for the moment.

Here is a link that might be useful to you.

Using 2D Picture Controls

[amit1986]

I am using CRICKET hardware for indoor localization of mobile robots.I am placing beacons on the ceiling of a L shaped corridor. I will be assigning the coordinates to these beacons by physically measuring the corridor. I want to draw this corridor as a map and side walls to be obstacle. I will roam my robot in this map and willl get robots coordinates by triangulation from three beacons. My reciever will be placed on the robot and reciever is connected to robot via RS232.I tried to retrive the data using VISA .In front panel i am getting the readins from each beacon one at a time. I want to store current data from three different beacons which gives distances and use these three distances to calculate the coordinates of reciever .

Reply soon.

Hi,

Thank for the clarification. That is much more helpful.

I think looking at the following example may be helpful to you:

Radar Sweep Using Picture Functions

If you look at the specific picture controls and the palette associated with them, you may find functions that can be adapted for your problem. You should easily be able to draw the corridor, the walls and then create a reference for your robot. The VI can be dynamically updated, so hopefully should allow adaption so that you can track your robot using triangulation.

I hope this helps.
