The sensor senses the surrounding environment and analyzes the driving state of the vehicle based on the information sensed by the sensor, thereby realizing intelligent driving.
Map information is initially used for travel navigation, and with the increase of information output by a map, not only can information such as longitude and latitude be output, but also information such as road section range, type and speed limit value can be output, so that functions such as active speed limit and electronic fence are realized.
And due to geographical factors and use scenes, part of the sensors cannot work normally, and even error information is output. Such as: the front-view camera cannot automatically judge whether the use environment meets the requirement of vehicle control.
Therefore, it is necessary to develop a forward-looking camera usage scene optimization method, system, vehicle, and storage medium.

step 2, judging whether the weather is sunny or not based on the extracted local weather information;
step 3, if the vehicle is on a sunny day, calculating the sun altitude angle and the sun azimuth angle of the current position of the vehicle according to longitude and latitude and time information output by navigation; when the solar altitude angle is larger than a first preset angle, the solar azimuth angle is larger than a second preset angle, the confidence signal of the camera is smaller than a preset value, and the duration time is longer than preset time, the function of the camera is degraded, otherwise, the camera normally outputs target information;
if the weather is rainy and above, and meanwhile the confidence signal of the camera is smaller than the preset value and the duration time is longer than the preset time, the function of the camera is degraded, otherwise, the camera normally outputs the target information.
Further, the camera function degradation means that the camera target output state is set to be invalid.
Further, if the camera has a fault or the navigation information is invalid, no judgment is made, and the camera keeps the previous working state.
In a second aspect, the usage scene optimization system for the foresight camera comprises the foresight camera, a vehicle-mounted navigation module, a positioning module, a memory and a controller, wherein the controller is respectively connected with the foresight camera, the vehicle-mounted navigation module, the positioning module and the memory; the vehicle-mounted navigation module is used for outputting navigation information, and the positioning module is used for positioning a vehicle; the memory stores a computer readable program, which when invoked by the controller, is capable of performing the steps of the method for using scene optimization for a forward looking camera as described in this embodiment.
In a third aspect, the present invention provides a storage medium, in which a computer readable program is stored, and the computer readable program, when being called, can execute the steps of the method for optimizing the usage scenario of the forward-looking camera according to the present invention.
The invention has the following advantages: the camera function can be degraded under the condition of poor environment according to navigation information, self fault information, sensor internal confidence coefficient and other information, so that the sensor can accurately sense peripheral targets, and the phenomena of false recognition and missing recognition are prevented.

Fig. 2 is a flowchart of the present embodiment.
Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 2, a method for optimizing a usage scenario of a forward-looking camera includes the following steps:
step 1, acquiring navigation information, and extracting local weather information from the navigation information;
step 2, judging whether the weather is sunny or not based on the extracted local weather information;
step 3, if the vehicle is on a sunny day, calculating the sun altitude angle and the sun azimuth angle of the current position of the vehicle according to longitude and latitude and time information output by navigation; when the solar altitude angle is larger than a first preset angle, the solar azimuth angle is larger than a second preset angle, the confidence signal of the camera is smaller than a preset value, and the duration time is longer than preset time, the function of the camera is degraded, otherwise, the camera normally outputs target information;
if the weather is rainy and above, and meanwhile the confidence signal of the camera is smaller than the preset value and the duration time is longer than the preset time, the function of the camera is degraded, otherwise, the camera normally outputs the target information.

In this embodiment, the camera function degradation refers to setting the camera target output state as invalid.
In this embodiment, if the camera has a fault or the navigation information is invalid, the camera does not enter any judgment and keeps the previous working state.
In this embodiment, the condition of the camera function degradation needs to be combined with navigation information, self fault information, and sensor internal confidence information. Under the condition of self or navigation function failure, corresponding judgment cannot be carried out, and meanwhile, the reliability is ensured through synchronous judgment of target output confidence of the sensor in consideration of possible inaccuracy of navigation information.
After the camera function is degraded by adopting the method, when the multi-sensor data is subjected to fusion processing, accurate perception of peripheral targets by each sensor can be ensured, so that the phenomena of false recognition and missing recognition are prevented.
