Problems solved by technology
However, the accuracy of wireless positioning methods such as Bluetooth and WIFI is poor, and they are significantly affected by environmental interference. The size of the passable partition in the supermarket is often not much different from the positioning accuracy of Bluetooth or WIFI positioning or is less than the positioning accuracy, resulting in the positioning deviation of the shopping cart. Larger, poor user experience, while the use of image acquisition for visual positioning has high positioning accuracy, but the calculation of positioning is large, and the requirements for processing modules are high

Embodiment Construction
[0051] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0052] In the existing smart shopping cart technology of supermarkets, wireless or visual positioning methods are usually used to locate the real-time position of the smart shopping cart. Wherein, the wireless positioning method may include wireless positioning methods such as Bluetooth positioning and WIFI positioning. The positioning accuracy of the current wireless positioning method is poor, and the interference of the environment is obvious. The usual positioning accuracy can only reach 3-5 meters, but the distance be...

The invention discloses a method for locating a shopping cart in a supermarket, which includes: collecting a reference image including a preset logo in the supermarket, processing the reference image to obtain the partition where the shopping cart is located as a positioning partition, wherein the supermarket includes a plurality of partitions , each partition corresponds to at least one of the preset identifiers; receiving distance information sent by signal transmission modules at multiple preset positions in the supermarket, wherein, each partition is provided with multiple signal transmission modules; according to the positioning The first positioning position of the shopping cart is obtained from the distance information of multiple signal sending modules corresponding to the partition as the actual position of the shopping cart. The invention also discloses a shopping cart positioning system for a supermarket and a shopping cart including the system. The invention can Reduce the calculation amount of shopping cart positioning in supermarkets and improve positioning accuracy.
Description
technical field [0001] The invention relates to the technical field of supermarket intelligent shopping carts. More specifically, it relates to a positioning method and system for a shopping cart in a supermarket, and a shopping cart in a shopping mall. Background technique [0002] At present, smart shopping carts usually include a positioning function, and existing shopping carts usually use wireless or visual positioning. However, the accuracy of wireless positioning methods such as Bluetooth and WIFI is poor, and they are significantly affected by environmental interference. The size of the passable partition in the supermarket is often not much different from the positioning accuracy of Bluetooth or WIFI positioning or is less than the positioning accuracy, resulting in the positioning deviation of the shopping cart. Larger, poor user experience, while using image acquisition for visual positioning, although the positioning accuracy is high, but the positioning calcula...
