Specifically, test piles are marked from the road surface image, the reference proportion is determined according to the pixel distance between the test piles, and the actual distance between the running track of the tested vehicle and each test pile is determined based on the reference proportion.
In this embodiment, the scoring rule is:
a basic score
The basic components are 10 minutes, and 8 minutes are qualified.
The vehicles to be tested bypass the test piles one by one according to the appointed sequence, and the total amount of 0.8 minutes is added to the pile-winding action which is successfully reached to the end point when the pile-winding action is completed.
And winding piles irregularly, and buckling 1 minute each time a test pile is knocked off or missed, until the pile winding project is 0 minute.
The time is divided into 2 minutes, and the time can be obtained after not less than 5 pile winding actions are successfully completed.
And recording the completion time, wherein the time exceeds 10 minutes, the task is forcedly ended, the time is divided into 0 points, and the total point of the task is calculated according to the effective passing vertical pile score.
The total score of the daytime is more than or equal to 8 minutes, and the night test can be carried out;
the total score at night is more than or equal to 8 minutes, and the next test can be carried out.
B additional sub-items
After the basic score is more than or equal to 8 scores, the square can calculate the additional score.
The vertical piles are wound one by one according to the appointed sequence, the test piles are not touched or the test piles are not wound, the shortest time is used, and 1 minute is added.
In the following process of the tested vehicle, the smallest maximum distance between the left side and the right side of the vehicle body is added by 1 minute.
Can continuously and smoothly follow the guiding person to advance, and the score is 1. In this embodiment, continuous, smooth following of the leader means that the vehicle under test cannot stop while following.
The nearest distance between the tested vehicle and the tested pile is close to the ideal distance (the ideal distance is (the distance between two adjacent piles is the vehicle width)/2), and 1 minute is added.
Evaluation score = base score + additional score.
When the base score is less than 8, the evaluation score=base score+additional score 0.
When the basic score is equal to or greater than 8, the evaluation score=basic score+additional score 1
Example two
The difference between the embodiment and the first embodiment is that in S503 of the embodiment, there are a plurality of cameras, at least 1 camera is controlled to shoot the road surface image of the tested vehicle after running in real time, and at least 1 camera is also controlled to shoot the image of the tested vehicle after running in real time; in this embodiment, the number of cameras is greater than 3.
S505, the server judges whether the running track of the tested vehicle is smooth, if not, whether the running track of the tested vehicle is smooth or not is judged based on the running image of the tested vehicle; if not, not processing is performed, if so, jumping to S506;
s506, controlling at least 1 camera to shoot a footprint image of the leader and a walking image of the leader, judging whether the walking of the leader is smooth based on the walking image of the leader, if so, judging whether the depths of the footprints of the leader are consistent, and if not, jumping S507;
s507, controlling at least 2 cameras to shoot road surface images of the tested vehicle after running in real time.
Because the wheel track recording belt and the wheel track recording ring are covered with sand dust or lime dust, even coverage is required, but uneven coverage can still occur due to factors such as manual coverage, strong wind of outdoor sites and the like. When the coverage is uneven, the variation of the depth of the trace of the vehicle is easy to be caused, and the accuracy of the follow-up extraction of the running trace of the tested vehicle is affected. According to the scheme, the situation that the vehicle marks are different in depth caused by unsmooth running of the vehicle can be eliminated, whether a place with uneven coverage exists in front of the detected vehicle or not is judged through the depth of the footprint of a guide person, if so, at least 2 cameras are controlled to shoot road images of the detected vehicle after running in real time, the definition of the shot road images is ensured through multi-angle shooting, the running track of the detected vehicle is conveniently extracted subsequently, and misjudgment caused by the fact that the running track is extracted intermittently and the vehicle runs smoothly is avoided. In other embodiments, if the coverage is uniform, more cameras may be scheduled to aim at the vehicle under test or the pilot, etc., with each camera functioning the most when appropriate.
