Problems solved by technology

[0003] However, with the rapid development of various camera parameters, cameras with large viewing angles and even ultra-large viewing angle cameras, such as cameras with a field of view greater than 100 degrees, often do not have a magnifying glass with a large field of view on the market. A new resolution test scheme that can reduce the test space

Abstract

The invention discloses a method for testing resolving power of a camera and equipment for regulating the angle of the camera to test the resolving power of the camera. The method comprises the following steps: a plane is provided, and a test pattern is arranged in the center of the plane; the position and the angle of the camera are regulated to enable the view field center of the camera to right face the test pattern, so that a test image of the view field center can be shot; the angle of the camera is regulated to enable the view field edge of the camera to be aligned with the test pattern, and a test image of the view field edge can be shot; the resolving power of the camera is calculated on the basis of the test image of the view field center and the test image of the view field edge. Test space can be reduced with the method for testing the resolving power of the camera.

Description

technical field [0001] The invention relates to the field of camera product testing, and more specifically, to a method for testing the resolution of a camera and a device for testing the resolution of the camera. Background technique [0002] In the prior art, the resolution test of the camera is usually performed by placing a plane scene at a specific test distance. The construction of the test environment requires a certain cost, such as the cost of site rental, the cost of making and constructing the plane scenery, the layout cost of the light layout of the test environment, etc. The larger the test environment, the higher the construction cost. In order to reduce the space requirements for the test environment and reduce the test cost, a magnifying glass can be placed between the camera and the flat scene to assist in the resolution test. [0003] However, with the rapid development of various camera parameters, cameras with large viewing angles and even ultra-large vi...
