Abstract: A method for aligning a camera lens with a light source is provided. The method is used in an aligning system. The aligning system includes an alignment element, a reference camera and a fixture. Firstly, the reference camera shoots a reference chart on the alignment element. Then, the light source is placed on the fixture. The light source illuminates the alignment element to generate an illumination result. The reference camera shoots the illumination result. If the illumination result does not comply with a preset specification represented by the reference chart, the fixture adjusts the light source. Then, the camera lens is placed on the fixture. Then, the camera lens shoots the reference chart on the alignment element to acquire a shooting result. If the shooting result does not comply with the preset specification, the fixture adjusts the camera lens.
