Automatic visual guide vehicle for constant illumination

Abstract

The invention discloses an automatic visual guide vehicle for constant illumination, comprising a vehicle body, an image acquiring device, an image processing device and a main control device, wherein the image acquiring device is arranged on the vehicle body; the image processing device is electrically connected with the image acquiring device; the main control device is electrically connected with the image processing device; the image acquiring device comprises a camera, a light source and an image processing unit; the camera is arranged on the vehicle body; the light source is coaxially arranged with the camera; the image processing unit is connected with the camera; a light-shading cavity for shading external light sources is also arranged on the vehicle body; and the camera and the light source are arranged inside the light-shading cavity. The automatic visual guide vehicle can not be affected by external illumination environments or can be rarely affected by external illumination environments, and after an image signal is acquired, a series of control instructions are output after shaping filtering of hardware and digitalized high-speed real-time processing of software so as to control an automobile to run accurately and complete various set actions.

Description

technical field [0001] The invention relates to automatic guided vehicle technology, in particular to a constant-illuminance visual automatic guided vehicle. Background technique [0002] Automated Guided Vehicle (AGV) plays an increasingly important role in modern logistics automated conveying systems and flexible manufacturing systems. It can carry a specific load and run autonomously between the departure point and the destination, which is of great significance for improving the degree of production automation and production efficiency. Therefore, AGV has been more and more widely used. The key technology in AGV is guidance technology. At present, the guidance methods of AGV have diversified trends. The methods generally include: track guidance, electromagnetic guidance, laser guidance, GPS guidance, coordinate recognition, inertial or Ultrasonic guidance, visual guidance, etc. [0003] Vision guidance has the advantages of relatively easy path planning and changes, r...

Problems solved by technology

During the image acquisition of path markings, there are changes in the external environment, such as: changes in weather, reflection conditions on the ground, differences in light in sunny and rainy days, natural lightning or artificial environmental bursts of light, etc. The pollution or defect of the marking line can reduce the image quality, affect the speed of image processing, and have a great impact on real-time and accuracy, which will affect the operation effect of AGV
