Monitoring method and system for optimizing desktop monitoring image quality

The invention discloses a monitoring method and system for optimizing desktop monitoring image quality. The monitoring method and system for optimizing desktop monitoring image quality are used for a desktop monitoring system. The monitoring system is used for optimizing quality of images outputted by a monitoring end. The method comprises the steps that step S100, the number of segmentation is calculated by a monitored end based on the preset segmentation coefficient and CPU utilization rate, and monitoring image data to be segmented are segmented according to the number of segmentation and image segments are obtained; and step S200, binary comparison is performed on the image segments and one previous image respectively by the monitored end, and the image segments of which the comparison results indicate difference are transmitted to the monitoring end. The invention also provides the monitoring system for optimizing desktop monitoring image quality. Performance of a network and the monitored equipment is coordinated so that influence of desktop monitoring on image quality can be reduced to the largest extent, quality of the images outputted by the monitoring end can be enhanced and equipment cost can be reduced.
