To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Fig. 1 is a kind of flow chart of the control method of automobile front lamp state provided in an embodiment of the present invention, should with reference to Fig. 1
Method may include:
Step 101 obtains the ambient image that vehicle front works as former frame.
In embodiments of the present invention, processing module and vehicle-mounted camera can be set in vehicle, which can
Think the camera in vehicle intelligent rearview mirror, or may be the camera being separately provided in vehicle.The processing module can
To be integrated in the vehicle intelligent rearview mirror, or what is be independently arranged in vehicle is used to control the module of light status.
Wherein, which can acquire the ambient image of vehicle front in real time, the processing module can in real time or
Person periodically obtains the ambient image of vehicle-mounted camera acquisition.Exemplary, the available vehicle front of the processing module is worked as
The ambient image of former frame.
Step 102 pre-processes the ambient image for deserving former frame.
In embodiments of the present invention, in order to improve the efficiency of image procossing, processing module is to the environment map got
As that can also be pre-processed to the ambient image, which can specifically include: remove the environment map before being detected
Redundant area as in, and/or, resolution decreasing processing is carried out to the ambient image.
Wherein, which may include the pixel that line number is preset on the ambient image top, the default line number and environment
The ratio of total line number of pixel is preset fixed value in image.Due to may include street lamp lamp in the ambient image of vehicle front
Light can impact the control of subsequent light status if the street lamp light is mistaken for the light of vehicle by processing module.?
In practical application, since the light of street lamp is normally at the top half of ambient image, in order to avoid the street lamp light
Interference can first remove the pixel that line number is preset on the ambient image top.Wherein, the top of the ambient image refers to ambient image
In close to sky part, the lower part of ambient image refer in ambient image close to ground part.
Wherein, resolution decreasing processing can be sampling processing, i.e. processing module can be according to preset oversampling ratio pair
Pixel in the ambient image is sampled, to extract the valid pixel in the ambient image.
It is exemplary, it is assumed that the ratio of total line number of pixel is 1/5th in the default line number and ambient image, the environment
Total line number of pixel is 1000 in image, then the processing module can be by the region where the 200 row pixel of ambient image top
It is determined as redundant area, and removes the redundant area.Further, which can be in the remaining ambient image
Pixel is sampled, such as every one valid pixel of a pixel extraction.Later, which detects the process again and locates in advance
It whether include highlight regions in ambient image after reason.
It should be noted that in practical applications, processing module can also first carry out at resolution decreasing the ambient image
Reason, then removes the redundant area in the ambient image again, and the embodiment of the present invention does not limit the execution sequence of two steps
It is fixed.
Step 103, to detect this pretreated when whether the average brightness of the ambient image of former frame is greater than the second brightness
Threshold value.
In embodiments of the present invention, it is pretreated when each in the ambient image of former frame can to calculate this for processing module
The brightness value of pixel, then total number of pixels of the brightness value further according to each pixel and ambient image, obtains the environment
The average brightness of image, and judge whether the average brightness is greater than preset second luminance threshold.When the average brightness is not more than
When the second luminance threshold, processing module can determine current environment dark images, therefore can continue to execute step 104；When this
When average brightness is greater than the second luminance threshold, processing module can determine that current environment is brighter, therefore can execute step 108.
Wherein, when calculating the brightness value of each pixel, which first can be converted to grayscale image by processing module
Then picture calculates the gray value of each pixel in the gray level image again, the gray value of each pixel can react the pixel
Brightness.
It is exemplary, it is assumed that second luminance threshold are as follows: gray value 100, the processing module is by the pretreated environment map
As after being converted to gray level image, the average gray value for the gray level image being calculated is 80, then since the average gray value is small
In preset second luminance threshold, therefore processing module can execute step 104.
Step 104, detect this it is pretreated when in the ambient image of former frame whether there is area be greater than the first area
The highlight regions of threshold value.
Wherein, which is that the brightness value of each pixel is all larger than the connected region of default first luminance threshold.When
Deserve there are when the highlight regions that area is greater than the first area threshold in the ambient image of former frame, processing module can execute step
Rapid 105；When highlight regions are not present in the ambient image for deserve former frame, or there is no areas to be greater than first area threshold
When highlight regions, processing module can execute step 109.
In embodiments of the present invention, the first area threshold can be previously stored in processing module, first area threshold
It can be measured by the number of pixel, such as first area threshold can be 100 pixels.Processing module will can be first somebody's turn to do
Pretreated ambient image is converted to gray level image, then traverses each of the gray level image using algorithm of region growing again
Pixel extracts all connected regions for being greater than default gray threshold, and calculates the area of each connected domain, and then judge again
It is greater than the highlight regions of the first area threshold in the gray level image with the presence or absence of area.Wherein, the specific reality of algorithm of region growing
Existing process can refer to the relevant technologies, and the embodiment of the present invention does not repeat them here this.
It is exemplary, it is assumed that first luminance threshold are as follows: gray value 120, the ambient image for deserving former frame are converted into gray scale
After image as shown in Fig. 2, then the processing module can be extracted from the gray level image gray value greater than 120 pixel it is (i.e. white
Color pixel 01) connected region that is constituted, and whether the number of pixels for detecting each connected region is greater than 100.Assuming that in Fig. 2 institute
In the gray level image shown, each lattice represents 10 pixels, then the processing module can determine exist in the ambient image
Two areas are greater than the highlight regions of the first area threshold, wherein each highlight regions include the white pixel 01 of multiple connections.
It should be noted that in practical applications, the specific value of first luminance threshold and the second luminance threshold can be with
According to circumstances set, the embodiment of the present invention to the size and specific value of two luminance thresholds without limitation.
Step 105, the ambient image for obtaining vehicle front next frame.Execute step 106.
When processing module is detected when there are the highlight bars that area is greater than the first area threshold in the ambient image of former frame
When domain, in order to further judge whether the highlight regions are to be generated by the headlight light for the vehicle that crosses, it can continue under acquisition
The ambient image of one frame.

If when former frame ambient image in area be greater than the first area threshold highlight regions number be greater than 1 (such as
For that 2), then can determine that two highlight regions may be that can continue due to caused by two headlamps of opposite vehicle
Obtain the ambient image of next frame.If when area is greater than of the highlight regions of the first area threshold in the ambient image of former frame
Number is equal to 1, then in order to avoid erroneous judgement, whether the area that processing module can continue to test the highlight regions is greater than second area threshold
Value, the second area threshold value are greater than first area threshold.When the area of the highlight regions is greater than second area threshold value, then locate
Reason module can determine a highlight regions may be due to caused by the bicycle lamp of the vehicles such as motorcycle, or due to turning
Caused by the headlamp of vehicle, then it can continue to the ambient image for obtaining vehicle front next frame.
Step 106 detects the highlight bar for being greater than the first area threshold in the ambient image of the next frame with the presence or absence of area
Domain.
When in the ambient image of the next frame there are area be greater than the first area threshold highlight regions when, execute step
107；When highlight regions of the area greater than the first area threshold are not present in the ambient image of the next frame, step 109 is executed.
