[0076] Of course, the camera can also identify specific markers in the environment in real time, such as two-dimensional codes, barcodes or special labels, and combine them with image processing algorithms to accurately calculate the current accurate position in real time. This is more suitable for indoor positioning, and requires human to arrange specific markers in advance.

[0077] S4, moving according to the route to the destination.

[0078] In the navigation mode, the box leads the user and serves as a guide for the user. The detection module detects the user's position. If the user deviates, the box moves following the user and re-plans the route to the destination.

[0079] In the state without user accompaniment, the box can be used for point-to-point delivery of files, goods, etc. according to the planned route.

[0080] In the following mode, the detection module identifies the user, and the control module controls the box to follow the user's movement. In this embodiment, the visual detection device 10 or the camera identifies the user through face, clothes, posture, etc.

[0081] It also includes a voice module. In the following mode, after receiving the user's destination instruction and planning the route, if the user deviates, the voice module will remind the user through voice.

[0082] By converting environmental data into three-dimensional models, the path planning for navigation can not only help understand the structure of the space, but also help users avoid blocked areas or choose a more flat path by analyzing the layout of obstacles.

[0083] By combining smart devices with augmented reality (AR) technology, real-time visual information and navigation information of the environment can be superimposed and displayed. This not only displays the path during navigation, but also labels nearby points of interest, enhancing the user's immersive experience. The smart device obtains environmental images through the camera, and then combines them with map and positioning system data to generate virtual navigation information.

[0084] Through communication with the server and smart devices, the box's positioning can use GSM / GPRS network positioning, or cellular base station positioning. Using the signal strength (RSSI) of the GSM base station and the positioning algorithm, the signal difference between multiple base stations is used to estimate the position. It can also use GPRS network assisted positioning, WiFi positioning technology, Bluetooth low power (BLE) positioning. The above positioning methods are all prior art and will not be described here.
