System and method for measuring depth of field for a camera

A method for measuring depth of field for a camera comprising:

• arranging, a collimators arrangement in a housing, wherein the collimators arrangement is fixed, and configured to simulate the images with a minimum focus length and a maximum focus length;
• positioning, a camera beneath collimators arrangement in order to capture the images projected by the collimators arrangement, wherein the camera is adapted to check image sharpness using a modulation transfer function;
• focusing, the camera from minimum to maximum if the modulation transfer function is within a predefined focus range;
• measuring, by an image sharpness measurement module, sharpness of the target image;
• measuring, by a lens parameter measurement module, a plurality of lens parameters;
• automatically measuring, by a plurality of first parameters of an automation processing module, the depth of field;
• automatically measuring, by a plurality of first parameters of the automation processing module, the depth of field, wherein the plurality of second parameters comprises a camera product code, number of collimators, minimum and maximum object distance, minimum and maximum modulation transfer function used by the automation processing module;
• receiving, by the automation processing module of a processing subsystem, a camera product code as an input from a user;
• reading, by the automation processing module of the processing subsystem, the file relevant to the camera product code and select a required number of collimators;
• loading, by the automation processing module of the processing subsystem, a plurality of optical parameters from the file and initiate a test process, wherein the test process is performed to determine a qualification of the depth of focus of the camera;
• recording, by the automation processing module, one or more measured values from the camera by the plurality of collimators;
• comparing, by the automation processing module, the recorded values with a plurality of corresponding required values from the file;
• and
• automatically deciding, by the automation processing module of the processing subsystem, the acceptance and non-acceptance of the camera product code based on the comparison of the recorded values with the predefined values from the file.
