In order to be able to evaluate the quality of individual images or videos captured from a vehicle (FZ) in a simple and cost-effective way, the invention proposes carrying out an evaluation of image quality (BWQ,G) on the basis of positions and/or movements of distinctive vehicle window components (FZSK), e.g those having markings (MK), in particular distinctive, e.g. artificially marked, windscreen wipers (WSSW) and/or rear window wipers (HSW), for reported positions (POSFZSK) of the vehicle window components (FZSK, WSSW, HSW) by means of a target-actual comparison of actual individual images(I-EB) or actual videos (I-VD) with target individual images (S-EB) or actual videos (I-VD), respectively, which are each captured from a vehicle (FZ), from an identical, vehicle-specific position relative to the vehicle window (FZS), depending on how well at least distinctive points, in particular the markings (MK), of the vehicle window components (FZSK, WSSW, HSW) can be recognised at target positions defined by the comparison for the reported positions (POSFZSK).
为了能够以简单和廉价的方式推断出从车辆(FZ)记录的个体图像或视频的质量或品质,建议基于显著的、例如具有标记(MK)的车窗玻璃组件(FZSK)的位置和/或运动,特别是显著的、例如人工标记的挡风玻璃雨刮器(WSSW)和/或后窗玻璃雨刮器(HSW)的位置和/或运动,针对所述车辆玻璃组件(FZSK,WSSW,HSW)的所报告的位置(POSFZSK)通过对实际个体图像(I‑EB)或实际视频(I‑VD)与额定个体图像(S‑EB)和/或实际视频(I‑VD)的额定‑实际比较,根据在针对所报告的位置(POSFZSK)通过比较定义的额定位置上识别出所述车辆玻璃组件(FZSK,WSSW,HSW)的至少显著点、特别是所述标记(MK)的程度有多好来执行根据质量或品质的图像评估(BWQ,G),其中所述额定个体图像是分别从车辆(FZ),从相对于车窗玻璃(FZS)的相同的特定于车辆的相对位置记录的。
