Visual navigation driving assisting system for grain combine harvester

Abstract

The invention relates to a visual navigation driving assisting system for a grain combine harvester. The visual navigation driving assisting system for the grain combine harvester comprises a camera, a grain combine harvester visual navigation path recognition system, a grain combine harvester visual navigation steering control system and a full-hydraulic mechanical steering system. The grain combine harvester visual navigation path recognition system is used for receiving a farmland scene image collected by the camera and performing calculation to obtain navigation path line parameters. The grain combine harvester visual navigation steering control system integrates the navigation path line parameters, harvester steering angle signals and harvester traveling speed signals and then outputs control instructions to the full-hydraulic mechanical steering system matched with the visual navigation driving assisting system. The full-hydraulic mechanical steering system matched with the visual navigation driving assisting system adjusts the steering angle of a rear axle steering wheel according to the control instructions so as to achieve steering control over the grain combine harvester. The visual navigation driving assisting system for the grain combine harvester combines a DSP and a single-chip microcomputer and is low in power consumption, capable of achieving equipment miniaturization, convenient to install and suitable for being popularized and used.

Description

technical field [0001] The invention relates to a visual navigation assisted driving system, in particular to a visual navigation assisted driving system for a grain combine harvester. Background technique [0002] With the development of agricultural modernization, grain combine harvesters have been widely used in agricultural harvesting, which not only improves productivity but also reduces labor intensity, especially plays an important role in the process of rushing to harvest and rush to plant. However, during busy seasons, the driver is prone to fatigue as the driver continues to drive for a long time, which in turn affects the quality of the harvest and the phenomenon of food waste. Especially since 2008, the food crisis has swept the world, and the food issue has become an international issue. Nowadays, while increasing food production in various countries, preventing food waste during harvesting has become an urgent problem to be solved. [0003] The assisted drivi...
