Method for obtaining and associating 2D image data with 3D image data, said 3D image data being based on first intensity peak positions (471; 571) resulting from light triangulation performed by an imaging system comprising a first light source for illuminating a measure object (220; 520) with first light (211; 512) and an image sensor for sensing reflected first light (413; 513) from the measure object (220; 520), wherein the light triangulation comprises to illuminate a first portion of the measure object (220; 520) with the first light (211; 512) and sense reflected first light (413; 513) from the first portion by the image sensor during a first exposure period (361-1) resulting in a first image (340-1) with first intensity peaks occurring at first sensor positions, SP1, (471; 571) and illuminate another, second, portion of the measure object (220; 520) adjacent to said first portion with the first light (211; 512) and sense reflected first light from the second portion by the image sensor during another, second exposure period (361-2) resulting in a second image (340-2) with second intensity peaks occurring at second sensor positions,SP2, and wherein the imaging system further comprises one or more additional, second, light sources for illuminating the measure object (220; 520) with one or more second lights , wherein the method comprises: - illuminating the measure object (220; 520) with said one or more second lights and sensing any reflected second light from the measure object (220; 520) by the image sensor during one or more third exposure periods (361-3) resulting in one or more third images (340-3), - selecting , for respective first sensor position, SP1, (471; 571) in the first image (340-1), a respective third sensor position, SP3, (473; 573) in said one or more third images (340-3) and providing said illumination with the one or more second lights such that during said one or more third exposure periods (361-3), any reflected second light from the measure object (220; 520) will result in higher intensity than reflected first light (413; 513) in the selected third sensor positions, SP3, (473; 573), and - obtaining 2D image data of respective selected third sensor position, SP3, (473; 573) in said one or more third images (340-3) and associating the obtained 2D image data with the first sensor position, SP1, (471; 571) that the respective selected third sensor position, SP3, (473; 573) was selected for, whereby the obtained 2D image data become associated with the 3D image data, whereby at least the step of associating is executed by a processing means. - illuminating the measure object (220; 520) with said one or more second lights and sensing any reflected second light from the measure object (220; 520) by the image sensor during one or more third exposure periods (361-3) resulting in one or more third images (340-3), - selecting , for respective first sensor position, SP1, (471; 571) in the first image (340-1), a respective third sensor position, SP3, (473; 573) in said one or more third images (340-3) and providing said illumination with the one or more second lights such that during said one or more third exposure periods (361-3), any reflected second light from the measure object (220; 520) will result in higher intensity than reflected first light (413; 513) in the selected third sensor positions, SP3, (473; 573), and - obtaining 2D image data of respective selected third sensor position, SP3, (473; 573) in said one or more third images (340-3) and associating the obtained 2D image data with the first sensor position, SP1, (471; 571) that the respective selected third sensor position, SP3, (473; 573) was selected for, whereby the obtained 2D image data become associated with the 3D image data, <EOS>
