Dimension evaluation system and method thereof

A dimension evaluation system, adapted for being electrically connected to a detecting instrument, wherein the detecting instrument inspects a target object and generates an instant image, and the dimension evaluation system comprises:

• a computing device, connected to the detecting instrument through a signal and built with an anomaly detection model, a three-dimensional feature prediction model, and a feature tracking prediction model, wherein the computing device receives the instant image, the anomaly detection model detects an anomalous feature on the instant image, to mark a selection box around the anomalous feature, and obtains location information, the three-dimensional feature prediction model calculates a dimension of the anomalous feature based on the instant image and the location information, and when it is determined that an anomalous feature detected in each current picture in the instant image is the same as an anomalous feature detected in a previous picture in the instant image, the feature tracking prediction model performs mathematical statistics on all dimensions of the same anomalous feature, and generates a mathematical statistics result of the dimension corresponding to the anomalous feature when the computing device receives a picture static signal;
• and
• a display device, electrically connected to the computing device, wherein the display device is configured to display the instant image, the selection box, and the mathematical statistics result.
