Embodiment Construction
[0044] The present invention provides a path prediction algorithm of the least squares method based on the idea of commensurability. Based on the real user trajectory, firstly, the coordinate points given in the data are processed, and reasonable coordinate points are screened out to improve the accuracy of prediction. Then calculate the user’s trajectory angle based on the screened coordinate points, and finally predict the next user’s trajectory angle based on the obtained user’s trajectory angle, using the commensurate idea and the least square method, and then according to the predicted angle, Time and speed plan the trajectory that the user may walk next time.
[0045] see figure 1 , the present invention is a least square method path prediction algorithm based on the concept of commensurability. On the data set based on the above-mentioned user movement trajectory points, firstly, the data points are preprocessed to improve the accuracy of prediction. Specific steps a...
