3D Hough Transform for Sphere Recognition on Point Clouds
For example the Hough Transform is a well known technique which is largely adopted in 2D image space In this paper we system- atically analyse different |
What is the formula for Hough transform?
[ H , theta , rho ] = hough( BW ) computes the Standard Hough Transform (SHT) of the binary image BW .
The hough function is designed to detect lines.
The function uses the parametric representation of a line: rho = x*cos(theta) + y*sin(theta) .Hough transform can detect lines, circles and other structures if their parametric equation is known.
It can give robust detection under noise and partial occlusion • It can give robust detection under noise and partial occlusion.
Borders between the regions are • Borders between the regions are straight lines.
How do you do the Hough transform?
Algorithm
1Determine the range of ρ and θ.2) Create a 2D array called the accumulator with the dimensions (num rhos, num thetas) to represent the Hough Space and set all its values to zero.
3) Use the original Image to do edge detection (ED).
4) Check each pixel on the edge picture to see if it is an edge pixel.
What is the code for Hough transform in Matlab?
P = houghpeaks(H,5,'threshold',ceil(0.3*max(H(:)))); Superimpose a plot on the image of the transform that identifies the peaks.
Find lines in the image using the houghlines function. lines = houghlines(BW,theta,rho,P,'FillGap',5,'MinLength',7);
