Method for inspecting an object surface, in particular for inspecting the surface of a powder bed with a multiplicity of powder particles, comprising the steps of - illuminating the object surface from a first direction and recording a first image of the object surface, wherein the first image has a multiplicity of first pixel values that represent the object surface with the illumination from the first direction, - illuminating the object surface from at least one further direction (26c, 28) and recording at least one further image of the object surface, wherein the at least one further image has a multiplicity of further pixel values that represent the object surface with the illumination from the corresponding further direction (26c, 28), - determining (74; 84) a first corrected image of the object surface using the first and the further pixel values, wherein the first corrected image has a multiplicity of first corrected pixel values representing the object surface, wherein the first corrected pixel values are determined in dependence on first differences (68; 82) between the first pixel values and the respectively corresponding further pixel values, - determining (84; 74) a second corrected image of the object surface using the first and the further pixel values, wherein the second corrected image has a multiplicity of second corrected pixel values which are determined in dependence on second differences between the first pixel values and the respectively corresponding further pixel values (82; 68), and - determining individual properties of the object surface using the first corrected image and using the second corrected image, wherein a first threshold value defining a first brightness value range is provided, and wherein the further pixel values are used in dependence on whether or not they are located in the first brightness value range in order to determine the first corrected pixel values, characterized in that a second threshold value defining a second brightness value range is provided, and in that the further pixel values are used in dependence on whether or not they are located in the second brightness value range in order to determine the second corrected pixel values, wherein the first threshold value and the second threshold value differ from each other, and wherein the first corrected image is a shadow-reduced image of the object surface, while the second corrected image is a reflection-corrected image of the object surface, or vice versa. - illuminating the object surface from a first direction and recording a first image of the object surface, wherein the first image has a multiplicity of first pixel values that represent the object surface with the illumination from the first direction, - illuminating the object surface from at least one further direction (26c, 28) and recording at least one further image of the object surface, wherein the at least one further image has a multiplicity of further pixel values that represent the object surface with the illumination from the corresponding further direction (26c, 28), - determining (74; 84) a first corrected image of the object surface using the first and the further pixel values, wherein the first corrected image has a multiplicity of first corrected pixel values representing the object surface, wherein the first corrected pixel values are determined in dependence on first differences (68; 82) between the first pixel values and the respectively corresponding further pixel values, - determining (84; 74) a second corrected image of the object surface using the first and the further pixel values, wherein the second corrected image has a multiplicity of second corrected pixel values which are determined in dependence on second differences between the first pixel values and the respectively corresponding further pixel values (82; 68), and - determining individual properties of the object surface using the first corrected image and using the second corrected image, wherein a first threshold value defining a first brightness value range is provided, and wherein the further pixel values are used in dependence on whether or not they are located in the first brightness value range in order to determine the first corrected pixel values, characterized in that a second threshold value defining a second brightness value range is provided, and in that the further pixel values are used in dependence on whether or not they are located in the second brightness value range in order to determine the second corrected pixel values, wherein the first threshold value and the second threshold value differ from each other, and wherein the first corrected image is a shadow-reduced image of the object surface, while the second corrected image is a reflection-corrected image of the object surface, or vice versa.
