Precision location technology is one of basic technologies to realize the farmland working machine automatic driving and prescription agriculture; it is an important content of modern intelligent agricultural machinery research. In order to study a low-cost and high-precision location system which can be applied in the small machine worked in the south paddy field, the study proposed a double laser sources location technology. With the known distance between two laser emitter, the dynamic emission angle of laser emitter can be acquired and the location coordinate of the moving machine can be a...
