Computing device and precision testing method of optical lens using the computing device

A computing device, comprising:

• a storage system;
• at least one processor;
• and
• a lens testing system comprising one or more programs that are stored in the storage system and executed by the at least one processor, the one or more programs comprising instructions to:
• control an imaging system connected to the computing device to generate an image of an object according to light rays reflected from the object and collected by an optical lens that is connected to the computing device, and obtaining the image from the imaging system;
• measure a dimension of the object in the image of the object;
• determine whether a measurement times of the object is equal to a preset times;
• determine a maximum value and a minimum value of the dimension of the object when the measurement times of the object is equal to the preset times, and calculating a difference between the maximum value and the minimum value;
• determine whether the lens agrees with a precision requirement according to the difference between the maximum and the minimum of the dimension of the object;
• and
• output a result that indicates whether the optical lens agrees with the precision requirement.

A non-transitory computer-readable storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of a computing device to implement a precision testing method of an optical lens, the method comprising:

• controlling an imaging system connected to the computing device to generate an image of an object according to light rays reflected from the object and collected by the optical lens, and obtaining the image from the imaging system;
• measuring a dimension of the object in the image of the object;
• determining whether a measurement times of the object is equal to a preset times;
• determining a maximum value and a minimum value of the dimension of the object when the measurement times of the object is equal to the preset times, and calculating a difference between the maximum value and the minimum value;
• determining whether the lens agrees with a precision requirement according to the difference between the maximum and the minimum of the dimension of the object;
• and
• outputting a result that indicates whether the optical lens agrees with the precision requirement.
