【摘要】:提出了一種新的移動(dòng)相機(jī)下的地面運(yùn)動(dòng)目標(biāo)分割方法,運(yùn)用一種稱為"多平面視差約束"的三視角約束方法把圖像序列中的每個(gè)像素點(diǎn)區(qū)分成背景區(qū)域和運(yùn)動(dòng)目標(biāo)區(qū)域.該方法是在"平面和視差"框架的基礎(chǔ)上提出來(lái)的,克服了之前幾何約束方法存在的視差問(wèn)題,而且不需要固定的參考平面.同時(shí),在相機(jī)跟隨目標(biāo)相同方向移動(dòng)時(shí),將極線約束的面退化問(wèn)題簡(jiǎn)化為線退化問(wèn)題.實(shí)驗(yàn)結(jié)果證明了該方法的優(yōu)越性.
[Abstract]:In this paper, a new method of ground moving object segmentation based on moving camera is proposed. Each pixel in the image sequence is divided into background region and moving object region by a three-view constraint method called multi-plane parallax constraint. The parallax problem exists in the constrained method, and no fixed reference plane is needed. At the same time, when the camera moves in the same direction with the target, the surface degradation problem with epipolar constraint is simplified as the line degradation problem. The experimental results show the superiority of the method.
