Laser Line Extraction Algorithms

A Laser Line Extraction (LLE) algorithm is required to create a depth map based on a sequence of profiles of the object captured by the camera sensor.

The objective of an LLE algorithm is to estimate the position where a laser line horizontally crosses a Region of Interest (ROI). The detection can be done by analyzing each column of a frame individually.

An LLE algorithm typically outputs a data array containing the vertical position of a detected laser line along of a ROI, i.e., each computed ROI produces a single data array. Figure 2 – Depth map generation illustrates the depth map generation.
