Abstract

The invention relates to the technical field of image detection, and particularly relates to a low-illumination wide-angle standard lamp box. The low-illumination wide-angle standard lamp box comprises a test box, a test frame, and a telescopic mechanism, wherein the test box is arranged in a closed manner; the test frame supports an imaging device; the telescopic mechanism is arranged between the test frame and the test box, and can drive the test frame and the test box to move oppositely; two ends of the telescopic mechanism are respectively connected with the test frame and the test box; a cradle head capable of fixing the imaging device is arranged on the test frame; and an opening available for photographing of the imaging device is formed in the test box and opposite to the cradle head. Through arranging the imaging device and the test box (a darkroom) separately, the telescopic mechanism can drive the imaging device and the test box to move oppositely, so a test environment can be constructed quickly; and when the imaging devices with different wide angles are tested, by adjusting the telescopic mechanism, the imaging devices can be quickly adjusted and a test dead angle is relieved; and thus, the test efficiency is greatly improved, and the test categories are enriched.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a low-illuminance wide-angle standard light box. Background technique [0002] At present, VR cameras, panoramic cameras, fisheye cameras, mobile phone cameras, tablet cameras, SLR cameras, civilian and professional cameras, automotive cameras, security surveillance cameras, medical image acquisition equipment, etc., these imaging devices or digital image acquisition systems, All involve the evaluation and detection of image quality. By building a standard detection environment or scene and using standard detection methods to detect the imaging quality of these devices or image acquisition systems, it can objectively reflect the performance of imaging devices or image acquisition systems. Therefore, it is very important to establish a standard environment for testing or evaluating the imaging quality of imaging equipment or imaging systems. At present, the image quality ...
