step S11: and recording the examination operation of the training images by the operator to obtain an examination operation set.
In applications of image inspection systems (image inspection software) configured on computing devices such as computers, such as diagnostic analysis in vehicle security systems, operators (such as image inspectors/diagnosticians) can become familiar with the manner in which the image inspection software operates by performing simulated inspection operations on the training images before making actual security determinations. However, how to ensure the accuracy and the operation efficiency of the image inspection operation of the operator is the key to ensure the security inspection effect and the security inspection efficiency in the practical application. The image inspection simulation method according to the embodiment of the present invention is a solution to the above problem.
