Intelligent row-controlled pesticide spraying machine capable of adaptively adjusting breadth and control method thereof

The invention provides a self-adaptive breadth adjustment type intelligent row-control pesticide spraying machine and a control method thereof.The pesticide spraying machine comprises a four-wheel-drive electric chassis, a spraying mechanism, an automatic row-control mechanism, a self-adaptive breadth adjustment mechanism, a spraying rod lifting mechanism and an electric control box; the electric control box controls the four-wheel-drive electric chassis, the spraying mechanism, the automatic row aligning mechanism and the self-adaptive width adjusting mechanism to jointly and cooperatively operate, the purposes of self-adaptively adjusting the working width and automatically adjusting the row spacing are achieved, and therefore intelligent automatic control is achieved to complete precise spraying operation. According to the invention, when the pesticide spraying machine enters a field to work, images of corn seedlings in front of the vehicle are shot in real time through two cameras respectively mounted abo
