Platform for testing performance of camera based on EMVA1288 standard

Abstract

The invention relates to a platform for testing performance of a camera based on an EMVA1288 standard. The method is used for testing the performance of the camera to be tested. The platform comprises an integrating sphere, a camera obscure, an optical power meter arranged in the camera obscure, a computer control system and a bracket, wherein a light inlet hole is formed in the camera obscure; the light inlet hole is matched with a light outlet hole of the integrating sphere; a double-dick filtering component and the camera to be tested are sequentially arranged in the camera obscure along an optical shaft direction of the light outlet hole of the integrating sphere; the double-dick filtering component comprises an optical filter and an attenuation sheet; the optical power meter is positioned between the double-dick filtering component and the camera to be tested and is far away from the optical shaft; the optical filter, the attenuation sheet, the optical power meter and the camera to be tested are arranged on the bracket and are connected with the computer control system; the computer control system calculates and processes attenuation values of light intensity and brightness, and the light power data monitored in real time so as to obtain the performance parameters of the camera to be tested specified in the EMVA1288 standard. The testing platform can test all the parameters specified in the EMVA1288 standard, and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of camera performance testing, in particular to a camera performance testing platform based on the EMVA1288 standard. Background technique [0002] EMVA1288 is the No. 1288 standard product catalog table published by the European Machine Vision Association (EMVA). It is a set of standards for calibrating the characteristics and performance data of image sensors and cameras for machine vision applications. [0003] Before the appearance of EMVA1288, there was no unified standard for image sensor and camera performance testing. Large manufacturers such as KODAK, DALSA, and SONY each have their own set of evaluation and testing standards. Some indicators have the same definition, and many indicators have different definitions. Therefore, it is difficult to compare the horizontal performance of image sensors and cameras from different manufacturers. In order to compare the horizontal performance of image sensor...
