The barcode panel comprises a stainless steel surface with a "zebra" pattern printed on it, consisting of black bars along the plate. When the barcode panel is placed in a river, some of the bars remain above the surface and are used as a reference to measure the water level. This approach is expected to be applicable in various bodies of water and regions, requiring only a camera to capture images and reducing the need for prior knowledge about the specific region. The barcode panel used in the experiments consists of 7 black bars with a spacing of 15 cm between each one, and each bar is 5 cm in height and 20 cm in width. Therefore, the barcode panel has dimensions of 155 cm x 40 cm. A schematic representation of the barcode panel deployed to a water body is shown in the following figure.

For this dataset, the barcode panel was inserted into a water tank at the Hydraulics Laboratory of the São Carlos School of Engineering, University of São Paulo. A P51-15-G-UC-I36-5V-R pressure transducer manufactured by SSI Technologies was fixed into the lower position of the barcode to measure the hydrostatic pressure of the tank's bottom. A ground-truth measurement was performed using a ruler. Two pictures, one from the front and one from the diagonal angle, were taken of the panel for each measurement.
