【摘要】:城市主干道路的識(shí)別和提取是路網(wǎng)綜合的關(guān)鍵步驟,而雙線道路則是大比例尺地圖數(shù)據(jù)中道路綜合的難點(diǎn)。針對(duì)城市雙線主干道識(shí)別問(wèn)題,基于Gestalt視覺(jué)準(zhǔn)則構(gòu)建候選雙線主干道線對(duì)的約束條件,提出了一種基于平行系數(shù)的雙線主干道識(shí)別方法。首先對(duì)道路網(wǎng)數(shù)據(jù)進(jìn)行拓?fù)涮幚?然后借助道路匹配思想,結(jié)合Hausdorff(HD)距離匹配方法識(shí)別出可能構(gòu)成雙線主干道的候選線對(duì)。再對(duì)候選線對(duì)進(jìn)行平行系數(shù)計(jì)算,當(dāng)平行系數(shù)滿足閾值條件時(shí),就判定該線對(duì)是構(gòu)成雙線主干道的弧段。最后根據(jù)構(gòu)成雙線主干道路段間的空間關(guān)系,將已識(shí)別的弧段連接成整條道路。實(shí)驗(yàn)證明,選取典型樣本方法正確設(shè)置閾值后,該方法能有效地提取道路網(wǎng)中的雙線主干道。
[Abstract]:The identification and extraction of urban trunk road is the key step of road network synthesis, while the dual road is the difficulty of road synthesis in large scale map data. Aiming at the problem of urban dual trunk road identification, a method based on parallel coefficient is proposed to identify the dual trunk road, which is based on the Gestalt vision criterion to construct the constraint condition of the candidate dual trunk road pair. Firstly, the road network data is topologically processed, and then, with the aid of the road matching idea and the Hausdorff HDD distance matching method, the candidate line pairs that may form the two-line main road are identified. Then the parallel coefficient of the candidate line pair is calculated. When the parallel coefficient meets the threshold condition, it is determined that the line pair is the arc of the two-line main road. Finally, the identified arcs are connected into the whole road according to the spatial relationship between the sections of the two-lane main road. The experimental results show that this method can effectively extract the two-line main road in road network after selecting the typical sample method to set the threshold correctly.
