    摘要:

    為解決樣本的手工獲取和常規(guī)的目視解譯難以適應(yīng)目前農(nóng)業(yè)土地資源信息自動(dòng)化提取的需求問(wèn)題,引入時(shí)空數(shù)據(jù)挖掘技術(shù),運(yùn)用關(guān)聯(lián)知識(shí)遷移學(xué)習(xí)機(jī)制,提出了一種基于知識(shí)遷移學(xué)習(xí)的高分辨遙感影像土地利用信息分類制圖方法(KTLC)。首先,運(yùn)用改進(jìn)的均值漂移算法對(duì)新的待分類制圖影像進(jìn)行分割獲得影像對(duì)象,然后,將分割后對(duì)象的矢量邊界與前時(shí)相土地利用矢量專題圖進(jìn)行配準(zhǔn)、嵌套,通過(guò)疊加分析獲取當(dāng)前影像中的不變對(duì)象,并通過(guò)光譜、空間信息閾值篩選完成不變對(duì)象的提純,進(jìn)而將歷史專題圖中的地物類別知識(shí)遷移到新影像對(duì)象上,建立新的特征與地物類別映射關(guān)系,最后,運(yùn)用決策樹(shù)構(gòu)建分類規(guī)則完成當(dāng)前影像的快速分類制圖,并將所提方法與利用易康(eCognition)軟件進(jìn)行分類(EC)的結(jié)果進(jìn)行對(duì)比。研究結(jié)果表明,對(duì)于2組實(shí)驗(yàn)影像,KTLC方法分類總體精度分別為88.61%、88.30%,EC方法分類的總體精度分別為89.87%、84.84%,2種方法分類制圖精度相當(dāng),但在效率方面,KTLC方法優(yōu)于EC方法。

    Abstract:

    Obtaining surface spatiotemporal data rapidly, automatically and accurately is an important issue in agriculture informationization and intellectualization. Samples obtained by manual and conventional manual visual interpretation are difficult to adapt the demands of current agricultural land resources information automatic extraction. At the same time, low altitude remote sensing technology as a kind of emerging technology for earth observation in recent years, with its flexibility, high efficiency, low cost, was widely used in the investigation of all kinds of resources. If only extraction information from single phase image, regardless of the historical image data set information extraction has been completed, it will cause information waste and repeated work. Based on this, spatiotemporal data mining technology was introduced, and related knowledge transfer learning mechanism was used, a novel landuse information classification method based on knowledge transfer learning (KTLC) was proposed. Firstly, new image was segmented by improved mean shift algorithm to obtain image objects. Secondly, the vector boundary of the objects and former historical landuse thematic map were matched and nested, invariant objects were obtained through overlay analysis, and purification of invariant object was finished by spectral and spatial information threshold filtering. The historical features category knowledge of thematic map was transferred to the new image objects. Finally, current images classification mapping was completed based on decision tree, and landuse classification mapping results were completed by the KTLC and eCognition for landuse information mapping classification (EC). The experimental results showed that KTLC could obtain accuracies equivalent to EC, and also outperforms EC in terms of efficiency.
