A method for detection of a change in the scene in an area. The method comprises the steps of recording (100) a digital image of the area using a sensor and transforming (110) the recorded image by an operator. The operator is based on a previous modelling of changes in the lighting in the area and on a modelling of how the sensor depicts the area in greyscale values in the recorded image. The method further comprises the step of comparing (120) the transformed image with a reference image of the area in order to detect a difference that indicates a change in the scene. |
