Abstract: A method for testing a camera module includes: making a lens barrel of the camera module to be aligned with a reference picture with a label; obtaining an image captured by the camera module; analyzing the image and identifying the label, and a first central point of the image; determining coordinates of the label and the first central point to obtain coordinates of an imaged label and a second central point of the image sensor, and calculating an actual distance between the imaged label and the second central point according to them coordinates; obtaining a value of an EFL of the camera module; calculating an angle between a center axis of a lens and a center axis of the image sensor according to the actual distance and the EFL; determining that whether the installation of the camera module satisfies the requirement by comparing the angle with a reference angle.
