    摘要: The invention is related to a method for calibrating a lighting module (1) of an automotive lighting device. Firstly, the lighting module (1) projects a light pattern (2), and some image capturing element (4) acquires the projected light pattern (2). Then, a control centre compares the projected light pattern (2) with an ideal light pattern (5), identifying parameters of scaling, tilting, shearing and/or displacement of the projected light pattern (2) with respect to the ideal light pattern (5). Finally, the control centre corrects the operation of the lighting module (1) with the values of scaling, tilting, shearing and/or displacement. An automotive lighting assembly configured to perform these steps is also provided.

    摘要: The invention provides a method for correcting a first light pattern provided by a lighting device (1) with a matrix of light sources (2). This method comprising the steps of providing a test light pattern (10), instructing the light sources (2) to project the test light pattern (10), choosing some key points (11) in the test light pattern (10) and identify the projection of the key points (21) in the projected light pattern (20), comparing the spatial position of the projection of the key points (21) with respect to the spatial position of the key points (11) in the test light pattern (10), thus obtaining a distortion factor and finally applying a correction factor to correct the distortion factor, thus obtaining a corrected light pattern (5), the correction factor being related to the distortion factor obtained in the previous step. The invention also provides an automotive lighting device (1) and an automotive lighting assembly.
