What is Hough Transform? The Hough transform in image processing is a technique used to detect simple geometric shapes in images. It works by transforming the image space into a parameter space, where the geometric shapes can be detected through the identification of patterns in the parameter space.
Hough Transform is a computer vision technique to detect shapes like lines and circles in an image. It converts these shapes into mathematical representations in a parameter space, making it easier to identify them even if they're broken or obscured.
What are 3D point clouds?
In 3D modeling, a point cloud is a set of data points in a 3D coordinate system—commonly known as the XYZ axes. Each point represents a single spatial measurement on the object's surface. Taken together, a point cloud represents the entire external surface of an object.
How is point cloud data collected?
A laser scanner captures point clouds with the highest accuracy. This process is completed by a trained technician to ensure proper collection of data and correct scanning methods.
