The invention discloses a visualization processing method and a visualization processing device. The visualization processing method comprises the following steps: determining a to-be-monitored region; acquiring an electronic map corresponding to the to-be-monitored region; acquiring a current position of each worker in the to-be-monitored region; according to the current position of each worker, labeling a mark of each worker on the electronic map; and displaying the electronic map labeled with the mark of each worker on a visualization monitoring page. By virtue of the visualization processing method and the visualization processing device, the technical problem in the related technology that the position distribution of workers cannot be directly known by a monitoring command center is solved.
