A method for denoising and classifying task point A system, a terminal device and a storage medium, As that initial task point in the distribution map of the task points to be proces are traversed, the number of task points of other task point within a preset range corresponding to the traversed current initial task points is obtained, and the target task points whose number of task points is larger than a preset number threshold value are selected as the initial center points from the initial task points; Each initial center point is treated as a category, the target distances between each initial task point and each initial center point are obtained respectively, and clustering each initial task point with the shortest target distance as a clustering condition, In order to achieve the classification of the initial task points, it can reduce the influence of human subjective factors, improve the accuracy of the classification of task points, and then improve the success rate of marketresearch tasks and task processing speed and efficiency, and can achieve the expected commodity market survey effect, and improve the user experience.
