IMAGE-BASED METHOD OF DEFINING A SCANNING AREA

Image-based method of defining a scanning area with a measuring radiation-based measuring device (10) such as a laser scanner, the method comprising roughly aligning a targeting axis (2) of the measuring device (10) towards an area of interest (1) to be scanned, the area of interest (1) having a coherent visual property, capturing with known orientation to the targeting axis (2) an image (3) covering the area of interest (1), displaying the image (3) to a user, manually selecting by the user of at least one pixel (p) of a group of pixels (7, 7s) representing the area of interest (1) in the image (3), automatically segmenting the group of pixels (7s) based on a similarity to the at least one selected pixel (p) using a machine learning algorithm, and automatically defining the scanning area based on border pixels (9i) of the first group of pixels (7s).
