Abstract

The invention discloses a test method and test system for the field of view of a lens. According to the scheme, arc equipment is adopted, a test arc is arranged on the inner wall of the arc equipment,multiple angle marks are arranged on the test arc, the test arc is imaged at the location of the test arc through a lens to be tested, and based on the principle that the arc with the same angle hasthe same length, the field of view of the lens to be tested can be obtained according to an image collected by the lens to be tested. Thereby, according to the technical scheme of the invention, within the allowable range of the resolution of the lens to be tested, the test accuracy of the field of view can be higher by setting the accuracy of the angle marks, the test method is simple, and the test efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of lens testing, and more particularly, to a testing method and a testing system for the viewing angle of a lens. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with image acquisition function are widely used in people's daily life and work, bringing great convenience to people's daily life and work An essential tool for life. [0003] The main component of the electronic device to realize the image acquisition function is the lens, and an important parameter to measure the performance of the lens is the field of view of the lens. In the prior art, the method for testing the field of view has low precision and low efficiency. SUMMARY OF THE INVENTION [0004] In order to solve the above problems, the technical solution of the present invention provides a method and a testing system for testing the field of view angle of a lens, wh...
