Abstract
An optical camera lens includes a first camera lens component including at least one first lens and a second camera lens component including a second lens barrel and at least one second lens mounted in the second lens barrel. The first and second lenses together constitute an imageable optical system. At least one of the two camera lens components has a smooth region located on an end surface of the camera lens component, and a connecting medium for fixing the first and second camera lens components together. A corresponding assembly method of the optical camera lens and a corresponding camera module and an assembly method thereof are also provided. The optical camera lens can improve a pre-positioning accuracy by improving a height measurement accuracy, and can use a distance measuring point as a feature point of image recognition so as to perform pre-positioning and active calibration.
