Abstract

The invention discloses a book inventory robot based on visual SLAM, and relates to the technical field of mechanical engineering. The invention includes a base, a surface of the base is provided with an installation groove, the inner surface of the installation groove is fixedly connected with a mobile positioning device, a surface of the base is fixedly connected with a protective cover, the inner surface of the protective cover is fixedly connected with a lifting encoder, and the shaft of the lifting encoder One end is fixedly connected with a transmission tooth, the axis of the transmission gear is connected with the base in rotation, one surface of the base is fixedly connected with a guide column, the side of the guide column is slidably connected with a lifting seat, and the side of the lifting seat is rotatably connected with a collar. The invention respectively records the displacement, elevation and rotation information of the robot through the mobile positioning device, the lifting encoder and the rotary encoder, so that each positioning and mapping is an independent individual, which avoids the error accumulation caused by the matching of the depth map before and after the visual SLAM technology, and improves the The accuracy of positioning is beneficial for the robot to perform image recognition.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a book inventory robot based on visual SLAM. Background technique [0002] In the collection and reading places of books such as major libraries, tall bookshelves are often built to place millions of books. This type of environment is characterized by dense placement of books and high mobility. In order to ensure timely statistics and maintain the book database, it is necessary to take stock of the books on the shelves in time. [0003] At present, the more advanced method generally adopted is to carry out inventory of books on a regular basis by people holding RFID scanning terminals. Due to the large storage area of ​​the library, the bookshelves are generally tall, which not only wastes manpower and material resources, but also reduces the inventory accuracy. However, the existing robots cannot identify empty bookshelves by scanning with RFID scanning termina...
