[0014] In this embodiment, the method is executed in a computer device, which can be an independent physical server or terminal, or a server cluster composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud servers, cloud databases, cloud storage and CDN; a training vehicle refers to a vehicle specifically used for students or professionals to perform actual operations and training. It is a mobile teaching tool that provides an environment that simulates real scenes, allowing trainees to perform actual operations and skill training on the vehicle; in this application, students can use the training vehicle to learn and train a certain operation project, and after the training is completed, a corresponding assessment is required to determine whether the student's operation level after training meets the standard, and the assessment process is performed on the training vehicle; the historical operation record is a video image of each operation project shot in the history recorded in the computer device; each operation link corresponds to the need for the operator to use certain body parts for operation, the body parts are the operation parts, and the video images in the historical operation record are the images of the operation parts operating; the standard action is the action in the video image shot specifically for evaluation and assessment pre-stored in the computer device, and the computer device stores the standard action of each assessment project and each operation link.

[0015] In the present application, for each assessment item (i.e., operation item), each operation link is recorded in the computer device; when the user is to be assessed on a certain assessment item, the operation part to be used for each step and the approximate shooting angle of the part are first determined based on the relevant images of the historical operation records; then, before the operator starts to perform the first operation part, the camera is moved to a position where the corresponding operation part can be photographed at the angle; then the camera is fine-tuned so that the operation part enters a set area, and the operation part in the image corresponding to the standard action is also within the set area, so that the operation action can be compared with the standard action more accurately; after the comparison, the degree of consistency between the two can be obtained. The user's score in the operation link can be obtained based on the degree of match, and the higher the degree of match, the higher the score; for the next operation link, the same process is carried out to obtain its operation link score, and this cycle is repeated and the scores of each operation link are accumulated to obtain a total score, and then it is judged whether the user meets the standard at a later stage; in the present invention, the camera can be moved to the part of the body to be used in the operation link that the user is about to perform, and then the operation actions that are truly related to each operation link can be recorded in a targeted manner, and the present invention can also compare the actions in the recorded real-time image with the standard actions, and then score the user's operation, thereby realizing automated assessment and improving the efficiency and accuracy of the assessment.

[0016] As a preferred embodiment, the determining the operation part corresponding to each operation link according to the historical operation record includes: S21: Obtain the historical video footage of the last time the user performed the project to be assessed; S22: taking a screen segment corresponding to the first operation link from the historical video screen; S23: identifying a body part of an operator in the image segment; S24: using the identified body part as the operation part of the operation link; S25: Take a picture segment corresponding to an operation link from the historical video screen, execute steps S23 to S24 to identify the operation part of the operation link, and repeat this step until the operation part of each operation link is obtained.

[0017] In this embodiment, the image of the body part performing the operation is captured, and the name of the body part in the image is recognized by using the existing scanning and object recognition technology to obtain the name of the operation part.

[0019] In this embodiment, the first set value can be 3mm, 5mm or other values, which are not limited here; the closest distance between any point on the second contour and the first contour is not greater than the first set value, that is, the first contour and the second contour are in a state of roughly overlapping, which facilitates the subsequent identification and comparison of the relative distance between the two.

[0020] As a preferred embodiment, a plurality of first contour points are taken on the first contour, and a plurality of second contour points corresponding to the first contour points are taken at corresponding positions on the second contour, and the real-time capture of the operation action of the operation part is to capture the real-time position of the second contour points; The degree of consistency between the comparison operation action and the pre-stored standard action corresponding to the operation link includes: S61: taking the first frame image of the real-time video screen as the first comparison image, and taking the first frame standard image as the second comparison image; S62: Calculating the contour point distance between each first contour point in the first comparison image and the corresponding second contour point in the second comparison image; S63: Calculate the average distance of each contour point; S64: determining the frame matching degree of the first frame image according to the average distance; S65: taking the next frame of the real-time video screen as the first comparison image, taking the next frame of the standard image as the second comparison image, executing steps S62 to S64 to obtain the frame consistency of the frame image, and repeating this step until the frame consistency of each frame of the operation link is obtained; S66: Determine the degree of consistency between the comparison operation action and the standard action according to the degree of consistency of each frame.

[0021] The degree of fit of any frame is calculated using the following formula: in, is the matching degree of the i-th frame, is the average distance corresponding to the i-th frame image, is the first adjustment coefficient; The degree of consistency between the comparison operation action and the standard action is calculated using the following formula: Where W is the degree of fit, n is the number of frame fits; The operation score of this operation link is obtained by the following formula: in, The operation score for this operation link is is the second adjustment factor.

[0022] In this embodiment, the first adjustment coefficient can be 20 or other values, and the second adjustment coefficient can be 10 or other values, which are not limited here. The degree of fit sought by the present invention is obtained by averaging the degrees of fit of each frame in an entire operation link, that is, the basis for calculating the degree of fit is refined to the operation action of each frame, which can characterize the degree of similarity between the operation action of each segment in the entire operation process and the standard steps. In particular, the score of the operation link is more representative, thereby improving the accuracy and fairness of the score assessment.

[0023] As a preferred embodiment, the total score is calculated according to the following formula: Among them, P is the total score, is the operation score of the mth operation link, is the mth weighting coefficient, and m is the number of operation links.
