The main principle of this method is that the relative displacement between a marking triangle, whose length of sides are all known,and the camera can be calculated by measuring the image position of the triangle. In this paper,two calculation methods were examined concerning their effectiveness,and the availability of this photogammetric method was determined. By employing the above-mentioned method, several turning tests were carried out. As the results of these tests, the following facts were ascertained. 1.The characteristic of the front wheel exerts influence especialy upon the turning efficiency of tractor. 2.According to the condition, the turning center moves forward and backward.}, pages = {319--332}, title = {トラクタ走行軌跡の写真計測}, volume = {61}, year = {1980} }
