S100. Construct a site model, and set multiple marked reference points in the site model.

In this step, build the site model, specifically, model according to the actual ratio, such as modeling according to the ratio of 1:1, build a three-dimensional site model, and set the corresponding mark reference on site according to the stacking rules of the goods on site point, the marking reference point is set with a label used separately for the marking reference point, that is, each cargo has an independent label, and each marking reference point has an independent label. In order to improve the accuracy, the marking reference point is set close to the goods, such as If there are a large number of goods stacked somewhere on the site, then set a marked reference point next to the goods. Since the size and size of the site are known, the distance between the marked reference points can be determined one by one by measuring the distance between the marked reference points. Position, build a three-dimensional coordinate system, then import the site model into it, you can determine the coordinates of each point in the site model, including the coordinates of the marked reference point.

S200. Obtain the movement data of the reader and the reading data, and divide the movement data of the reader according to the reading operation time in the reading data to obtain independent movement data.

In this step, the movement data and reading data of the reader are obtained. During the modeling process, a three-axis acceleration sensor is set on the reader, and the acceleration of the reader in various directions can be obtained through the three-axis acceleration sensor. By integrating the acceleration curve, the moving speed of the reader in each direction can be calculated. Therefore, by collecting the acceleration data collected by the three-axis acceleration sensor, the moving path of the reader can be calculated accordingly, and the reading data is The data obtained when the reader reads the tag not only includes the information of the goods or the marked reference point, but also includes the time information of the reading operation.
