    摘要:

    以VC++為工具,，田間實拍圖像為研究對象，在分析田間秸稈和土壤紋理特征差別的基礎(chǔ)上,，設(shè)計了BP神經(jīng)網(wǎng)絡(luò)秸稈覆蓋率檢測系統(tǒng),。該系統(tǒng)采用了神經(jīng)網(wǎng)絡(luò)與紋理特征相結(jié)合的方法提取秸稈，并以紋理特征熵值為標(biāo)準(zhǔn)建立了網(wǎng)絡(luò)輸入層學(xué)習(xí)樣本選取準(zhǔn)則,。人工模擬和田間試驗表明,，設(shè)計的BP神經(jīng)網(wǎng)絡(luò)秸稈覆蓋率檢測系統(tǒng)對田間秸稈的識別率達90%以上，秸稈覆蓋率計算誤差可控制在5%以內(nèi),；與傳統(tǒng)的拉繩法相比,，檢測效率提高

    Abstract:

    50～120倍。According to the analyses of the texture differences between straw and soil, a new BP neural network measuring system for residue cover rate is designed. By taking the filed photos as the research objectives, this system was developed through VC++ programming tools. Straws were detected by combining the texture features and BP neural network. Selection standard of learning samples for input nodes was constructed based on the entropy in the system. Artificial simulation and field testing indicated that the new measuring system could detect over 90% of the straws in the field and control the counting error of residue cover rate under 5%. Compared with the traditional manual measuring, the measuring efficiency in the new system could be improved by 50～120 times. 
