Description

A Device For Evaluating Image Quality Of A Camera During Driving The present invention relates to a camera driving image quality evaluation device, and more specifically, to a device for evaluating the image quality of a vehicle camera during driving. Due to the nature of cameras, automotive cameras must be able to identify moving objects to achieve their original purpose. Here, since moving objects can be high-speed vehicles or low-speed people, the ability to accurately identify objects of various speeds is an important criterion for the quality of automotive cameras. To evaluate the image quality of such automotive cameras, a method of testing on actual objects was proposed; however, due to limitations in the shooting environment and the irregularity of object shapes, experiments could not be conducted quantitatively. Furthermore, as the results were influenced by various external factors in the actual field during shooting, there was a problem in that the performance and quality of the automotive cameras could not be accurately tested. To improve this, a device for testing while moving an object within a laboratory has been developed, and Patent Document 1 also discloses such a device. However, while Patent Document 1 allows for performance and quality evaluation regarding moving objects, it cannot evaluate how the camera captures in situations encountered on actual roads. In particular, since recent automotive cameras require information acquired by the camera to affect the driving of the vehicle for autonomous driving, it is necessary to evaluate whether the camera can capture accurately in situations such as snow, rain, and light reflection.
