Abstract
(EN) An image processing method and apparatus, and a movable platform. The method comprises: an image acquisition device cyclically acquiring images according to N different amounts of exposure; for a frame of first image currently acquired by the image acquisition device, fusing the first image and an (N-1) frames of second images acquired before the first image, so as to obtain a first high-dynamic-range (HDR) target image, the (N-1) frames of second images having different amounts of exposure from one another and having a different amount of exposure from the first image; and fusing the first image and (N-1) frames of third images acquired after the first image, so as to obtain a second HDR target image, the (N-1) frames of third images having different amounts of exposure from one another and having a different amount of exposure from the first image. By means of the repetitive use of each frame of image acquired by the image acquisition device and the fusion of each frame of image and images acquired before and after same, more HDR images can be obtained by means of synthesis, thereby greatly increasing the frame rate of the acquired HDR images.
(FR) Procédé et appareil de traitement d'images, et plateforme mobile. Le procédé comprend : un dispositif d'acquisition d'images acquérant cycliquement des images selon N quantités différentes d'exposition; pour une trame de première image actuellement acquise par le dispositif d'acquisition d'images, la fusion de la première image et de (N-1) trames de deuxièmes images acquises avant la première image, de façon à obtenir une première image cible à haute gamme dynamique (HDR), les (N-1) trames de deuxièmes images ayant des quantités d'exposition différentes les unes des autres et ayant une quantité d'exposition différente de la première image; et fusionner la première image et (N-1) trames de troisièmes images acquises après la première image, de façon à obtenir une deuxième image cible HDR, les (N-1) trames de troisièmes images ayant des quantités d'exposition différentes les unes des autres et ayant une quantité d'exposition différente de la première image. Grâce à l'utilisation répétitive de chaque trame d'image acquise par le dispositif d'acquisition d'images et à la fusion de chaque trame d'image et des images acquises avant et après celle-ci, il est possible d'obtenir davantage d'images HDR par synthèse, ce qui augmente considérablement la fréquence d'images des images HDR acquises.
(ZH) 一种图像处理方法、装置及可移动平台。所述方法包括:可以让图像采集设备循环地按照N种不同的曝光量进行图像采集,针对图像采集设备当前采集的一帧第一图像,可以将第一图像与在第一图像之前采集的N-1帧曝光量各不相同,且不同于第一图像的曝光量的第二图像融合,得到高动态范围的第一目标图像,同时,可以将第一图像与在第一图像之后采集的N-1帧曝光量各不相同,且不同于第一图像的曝光量的第三图像融合,得到高动态范围的第二目标图像。通过重复利用图像采集设备采集的每一帧图像,将其分别与之前采集和之后采集的图像融合,可以合成得到更多的HDR图像,大大提高采集的HDR图像的帧率。
