hhmm....how to find the center point of 2 lines using the visual c++. i need to find the center point of a track...actually,i'm using the video instead of static image. i have already got the binary image and stuck at this stage. please help me anyone?

What two lines?  What is the center point of two lines? Mark

Have you troubles with (1) C++ language? (2) Analytic geometry? (3) Windows programming? (4) Bitmaps (5) All of the above stuff? :)

Hi, Do you mean "intersection point of 2 lines"? If so, find equation of both lines, at the point of intersection both equations are same. If not, Explain the problem more clear. Best Regards, Suman

Very simple! ;P But you have to explain the scenario clearly...I have done same the thing you have puzzled. Explain it again! :)

Thanks a lot

let say, there is a track....my mobile root need to move along the track...the track is about 3 cm width...the reference for the mobile robot is the center point of the track...how can i get the center point?

yups...quite urgent...

The midpoint between two points (x1,y1) and (x2,y2) could be found something like (xMid, yMid) =  ((x1 + x2) / 2, (y1 + y2) / 2) I imagine for those two points, you'll need points on your detected lines that are perpendicular to the robot...or something like that. You'll need to do a little math :) Mark

Assuming the track delimiting lines parallel, at every point (of one of the two lines) you have to find the perpendicular line and choose on it the point that is halfway the two lines of the track. :)
