Method for a completeness check of a container holding a plurality of objects by way of a 3D camera, which provides a three-dimensional image of the objects, and a multi-ROI, wherein the multi-ROI comprises a plurality of ROIs which have a form that is settable by a user and are arranged within the multi-ROI in a number of rows, columns and in a grid type, which are settable by a user, having a learning mode and a temporally subsequent working mode, wherein the learning mode includes the following steps: capturing an image of the objects in the form of a three-dimensional pixel matrix using the 3D camera, wherein the pixel matrix contains in one dimension distance values of the captured objects from the 3D camera and contains in the two other dimensions location values in respective planes perpendicular thereto, reproducing the captured image as a two-dimensional image with the location values in a first image region, displaying input fields (10, 11, 14) for the form and the number of the rows, columns and the grid type of the ROIs, displaying a two-dimensional multi-ROI with a number of rows, columns and a grid type of the ROIs, which are input by the user, and a form, which is input by the user, of the ROIs in the first image region, adapting the size, the position and the rotation of the multi-ROI to at least one input by the user, adapting the size of the ROIs to at least one input by the user, displaying height values, derived from the distance values, for each ROI in a second image region, which differs from the first image region, displaying a lower limit and/or an upper limit for the height values in the second image region, adapting the lower limit and/or the upper limit for the height values to at least one input by the user, and changing to the working mode, wherein the working mode includes the following step: displaying a state of a respective ROI, wherein the state of the respective ROI is one of the states "overfill" and/or "underfill" and "good" and wherein the state "overfill" is displayed when the height value of the respective ROI lies over the upper limit, the state "underfill" is displayed when the height value of the respective ROI lies under the lower limit, and the state "good" is displayed when the height value does not lie outside a designated limit. capturing an image of the objects in the form of a three-dimensional pixel matrix using the 3D camera, wherein the pixel matrix contains in one dimension distance values of the captured objects from the 3D camera and contains in the two other dimensions location values in respective planes perpendicular thereto, reproducing the captured image as a two-dimensional image with the location values in a first image region, displaying input fields (10, 11, 14) for the form and the number of the rows, columns and the grid type of the ROIs, displaying a two-dimensional multi-ROI with a number of rows, columns and a grid type of the ROIs, which are input by the user, and a form, which is input by the user, of the ROIs in the first image region, adapting the size, the position and the rotation of the multi-ROI to at least one input by the user, adapting the size of the ROIs to at least one input by the user, displaying height values, derived from the distance values, for each ROI in a second image region, which differs from the first image region, displaying a lower limit and/or an upper limit for the height values in the second image region, adapting the lower limit and/or the upper limit for the height values to at least one input by the user, and changing to the working mode, wherein the working mode includes the following step: displaying a state of a respective ROI, wherein the state of the respective ROI is one of the states "overfill" and/or "underfill" and "good" and wherein the state "overfill" is displayed when the height value of the respective ROI lies over the upper limit, the state "underfill" is displayed when the height value of the respective ROI lies under the lower limit, and the state "good" is displayed when the height value does not lie outside a designated limit.
