Camera detection method

Abstract

The invention relates to a camera detection method, which comprises the following steps: step 1, preparing a detection support, the upper part of the support being a fixing position for fixing a camera to be detected, the lower part of the support being a workbench, and the camera to be detected fixed at the fixing position being capable of shooting the workbench; step 2, preparing a target sheet,selecting a sheet-shaped object as the target sheet, and drawing or pasting a target on the surface of the target sheet, the target having an outer circle and a cross-shaped intersection located inside the outer circle; step 3, fixing the target piece to a workbench, wherein the center of a target in the target piece and the central axis of the fixing position are located on the same straight line; step 4, starting a to-be-tested camera, and photographing the workbench by the to-be-tested camera to obtain a photographed picture with a target; and step 5, analyzing the shot picture with the target, measuring the distance between the center of the target and the center of the picture, and recording the distance as an offset value A. The invention provides a camera detection method which canquickly and accurately distinguish defective products in a camera.

Description

technical field [0001] The invention relates to the detection field, in particular to a camera detection method. Background technique [0002] During the production process of the camera, there will inevitably be industrial errors in the installation of the lens. In the camera industry, there is an agreed allowable range for the error value of the camera. For the camera whose error value is within the allowable range, it can be marked as a good product, and for the camera whose error value exceeds the allowable range, it needs to be marked as a defective product, but currently The industry lacks an efficient and reliable camera defect detection method, and cannot quickly and accurately sort good and defective products, which needs to be improved urgently. Contents of the invention [0003] In view of this, the present invention provides a camera detection method, which can quickly and accurately distinguish defective products in the camera. [0004] The object of the pre...
