a TV distortion與optical distortion會(huì)依不同視場(chǎng)定義不同。
TVdistortion是等比例放大失真，是線性的的關(guān)系。所以并沒(méi)有變形。 sU>IE To 這個(gè)要結(jié)合distortion的曲線和grid一塊看。 [xiqlb ,8 我猜是這樣的

64up! What is distortion? y'm!h?8 Distortion is the ratio of the change between the center and edge areas of a captured image. Due to the aberration of the lens, the distortion is more noticeable at the edges of a captured image. There are two types of distortion: barrel distortion and pincushion distortion. The general rule is that when the absolute value of the distortion value is smaller, the lens offers higher accuracy. j!agD_J *47/BLys< Calculating formula U~D~C~\2; TV distortion (Dtv) = Δh/2h x 100 (%) l qfTF A positive value of TV distortion indicates R=~%kt_n pincushion distortion and a negative value Z3&}C h indicates barrel distortion.
