It should be noted that, because the abnormal illumination information includes illumination information with too much illumination and illumination information with too much illumination, the server 11 includes two storage spaces, one is used for storing the illumination information with too much illumination, and the other is used for storing the illumination information with too much illumination.
In one embodiment, as shown in fig. 2, a route evaluation method is provided, which is illustrated by way of example as applied to the target vehicle 10 in fig. 1, and includes the following steps:
step S20, obtaining abnormal illumination information in a plurality of driving planning routes; the abnormal illumination information is illumination information which is obtained by analyzing the obtained illumination value through a vehicle and does not meet the requirement of human eye comfort level;
in the embodiment of the invention, the abnormal illumination information is the abnormal illumination information detected by other vehicles, and when the other vehicles detect the abnormal illumination information, the other vehicles upload the abnormal illumination information to the server so as to be used by all vehicles in the internet of vehicles. Optionally, the other vehicles may also directly upload the abnormal illumination information to the target vehicle. The target vehicle also analyzes the acquired illumination value and sends the abnormal illumination information to the server or other vehicles.
Wherein, the abnormal illumination information refers to illumination information which does not conform to the comfort level of human eyes.
The abnormal illumination information may include an illumination position at the time of abnormal illumination detected by another vehicle (which may also be referred to as a position at the time of abnormal illumination detected by another vehicle, where a Global Navigation Satellite System (GNSS) positioning technology is one of methods for acquiring the above position), a vehicle driving direction at the time of abnormal illumination detected by another vehicle, time, illumination intensity, and the like.
In the embodiment of the invention, if the target vehicle wants to go from the place a to the place B, the target vehicle can obtain a plurality of driving planning routes from the place a to the place B with similar time cost by using the navigation system of the vehicle, and the target vehicle can obtain the abnormal illumination information on the driving planning route from the server according to the driving planning routes and the abnormal illumination information containing the position in the server.
And step S21, according to the abnormal illumination information in each driving planning route, carrying out comfort evaluation on each driving planning route to obtain an evaluation result of each driving planning route.
In the embodiment of the present invention, the comfort level evaluation is an evaluation of the driving planning route according to the abnormal lighting information, for example, the comfort level evaluation is an evaluation of an abnormal lighting position or an abnormal lighting intensity in the abnormal lighting information.
In the embodiment of the present invention, the evaluation result is a representation of the comfort level of the driving planning route, for example, the larger the evaluation result of a certain driving planning route is, the more abnormal the illumination environment on the driving planning route is, and the smaller the evaluation result of a certain driving planning route is, the more comfortable the illumination environment on the driving planning route is.
According to the route evaluation method, the abnormal illumination information in the plurality of driving planning routes is obtained, the comfort level of each driving planning route is evaluated according to the abnormal illumination information in each driving planning route, the evaluation result of each driving planning route is obtained, and therefore the routes can be evaluated according to illumination.

Optionally, the illumination value may be directly obtained by using an illumination sensor, or an image including illumination may be obtained by using an image acquisition device, and pixels in the image may be analyzed to obtain the illumination value. And then, the vehicle analyzes the illumination value to obtain abnormal illumination information. The method for obtaining the abnormal illumination information mainly comprises two methods:
in the first method, if an illumination value is directly obtained by using an illumination sensor, the illumination value is respectively compared with a first preset threshold and a second preset threshold, wherein the first preset threshold is greater than the second preset threshold; the first preset threshold value represents a limit value of over-strong illumination, and the second preset threshold value represents a limit value of over-dark illumination; if the illumination value is larger than a first preset threshold, taking the difference value between the illumination value and the first preset threshold as the abnormal illumination intensity; and if the illumination value is smaller than a second preset threshold value, taking the difference value between the second preset threshold value and the illumination value as the abnormal illumination intensity. It should be noted that the first preset threshold and the second preset threshold are preset according to performance parameters, geographical locations, and the like of the lighting sensors.
In the second method, if an image including illumination is acquired by using an image acquisition device, pixels in the image are analyzed to obtain an average value of all pixels or an average value of local area pixels, and the average value of all pixels or the average value of local area pixels is used as an illumination value. Then, comparing the average value of all pixels with a third preset threshold and a fourth preset threshold respectively, wherein the third preset threshold is larger than the fourth preset threshold, the third preset threshold represents a limit value with over-strong illumination, the fourth preset threshold represents a limit value with over-dark illumination, and if the illumination value is larger than the third preset threshold, the difference value between the illumination value and the third preset threshold is used as the abnormal illumination intensity; and if the illumination value is smaller than a fourth preset threshold, taking the difference value between the fourth preset threshold and the illumination value as the abnormal illumination intensity. It should be noted that the third preset threshold and the fourth preset threshold are preset according to performance parameters, geographic positions, and the like of the image capturing device.
