• Overview And Setup
• Line Tracking Function Guide

1.1 Recognize Intersections and Output Data

Under the Line Tracking function, HUSKYLENS 2 can mark the trajectory of the line in the frame and acquire the current line's length, angle, and X, Y components. When the line branches, it can get the number of branches at the intersection and the corresponding data for each branch, starting counterclockwise.

Example Program:

Output Result: As shown, point the HUSKYLENS camera at a map with lines. Observe the Mind+ serial port output, which can display data such as the current line's length and angle. When the line has multiple branches, it can output the number of branches.
