Description

Technical Field

[0001] The utility model relates to the technical field of AGV navigation protection, in particular to a three-way visual protection component for anti-fog handling robot navigation. Background Art

[0002] In recent years, with the increasing demand for automation in the logistics and transportation industry, the demand for AGVs has further increased. When dealing with today's changing and complex application environments, SLAM navigation is more flexible and has lower maintenance costs compared to geomagnetism or reflectors, and will be the future development trend. Among them, visual SLAM is relatively less mature compared to laser SLAM, and there are still situations where feature point positioning is lost or the error is large during the process. In response to this situation, the method of adding a camera for QR code scanning and positioning is used as an auxiliary method to compensate for the visual positioning of SLAM, so as to ensure the correction and accuracy of positioning. Therefore, in addition to the navigation camera, a QR code scanning and positioning recognition camera also needs to be added to assist in precise visual SLAM positioning by scanning QR codes in the venue. At the same time, in high and low temperature application environments, the application of visual cameras will be affected by water vapor and affect the line of sight, so it is also necessary to design anti-fog for the camera glass. For this reason, a three-way visual protection component for anti-fog handling robot navigation is proposed. Summary of the Utility Model
