One kind of guidance based on global positioning system and method for multi-sensor

The present invention discloses a global positioning guide system and method based on multi-sensor, comprising: AGV vehicle, embedded controller, an acceleration sensor, a vision sensor, a light source, guide strip, wherein the guide belt comprises a guide wire and icon dimensional code, an acceleration sensor for measuring acceleration values ​​of the vehicle body AGV; visual sensor for obtaining image tape guide information included in the ground, automatic guiding function; the embedded controller calculates acceleration values ​​obtained by vehicle AGV relative position, while the position information of the global visual sensor through the two-dimensional code recognition icon defined realize the global positioning function AGV vehicle body. The present invention employs a guide surface belt, and to achieve automatic guided AGV global positioning function by the method of the acceleration sensor and the visual sensor combination provides the basis for multi AGV intelligent control, has good application prospect.
