用非量測相機所獲取的數(shù)據(jù)進(jìn)行試驗,對兩種算法進(jìn)行驗證。從實驗中可以得出如下結(jié)論:(1)這兩種方法都能夠應(yīng)用于大傾角的近景攝影測量中。(2)這兩種方法在相鄰攝站點的位置差很大時也同樣適用。(3)通過上述兩種方法完成像片的相對定向,在此基礎(chǔ)上繼續(xù)進(jìn)行模型連接、絕對定向和光束法平差,這樣一種多基線攝影及其整體處理的方法改變了傳統(tǒng)的直接線性變換、單模型處理方式,不僅需要的控制點數(shù)量大大減少,而且其精度也有很大提高。(4)測量精度與控制點數(shù)量有關(guān),控制點越多精度越高。(5)交向攝影的測量精度要比正直攝影高。在進(jìn)行光束法平差時,若將鏡頭畸變等參數(shù)加入,即進(jìn)行自檢校區(qū)域網(wǎng)平差,則精度還能有所提高。參考文獻(xiàn)[1] 張祖勛,楊生春,[J].地理空間信息,2022,5(1):1.
