Integrity degree analytical equipment is connect with the pattern extract equipment, for receiving the target rain brush pattern and in advance
If rain brush benchmark shape carries out similarity analysis, when similarity is more than limitation, integrity degree identification signal is issued.
Then, continue to carry out further the specific structure of the automatic reporting system of auto parts state of the invention
It is bright.
In the automatic reporting system of auto parts state: in the integrity degree analytical equipment, when similarity does not surpass
When crossing limitation, incomplete identification signal is issued.
In the automatic reporting system of auto parts state: in the spiced salt initial survey equipment, the picture for being 0 by gray value
Vegetarian refreshments is determined as green pepper initial survey pixel.
In the automatic reporting system of auto parts state: being 255 by gray value in the spiced salt initial survey equipment
Pixel is determined as salt initial survey pixel.
In the automatic reporting system of auto parts state: the spiced salt filter apparatus includes that the spiced salt reception is set
Standby, the described sub- equipment of window filtering and the gray scale export sub- equipment.
In the automatic reporting system of auto parts state: in spiced salt confirmation equipment, by the tempered glass
The pixel that spiced salt confirmation pixel is not belonging in image is all set to non-spiced salt confirmation pixel.
In the automatic reporting system of auto parts state: the audio processing equipment is also used to scrape in the glass
When the amplitude of sound does not transfinite, signal working properly is issued.
In the automatic reporting system of auto parts state: the driver's cabin camera is also used to receiving the work
When making normal signal, stop the shooting carrying out to the tempered glass.
In addition, in the spiced salt filter apparatus, filtering, i.e., to target figure under conditions of retaining image minutia as far as possible
The noise of picture is inhibited, and is indispensable operation in image preprocessing, after the quality for the treatment of effect will directly influence
The validity and reliability of continuous image procossing and analysis.
Not perfect due to imaging system, transmission medium and recording equipment etc., digital picture formed at it, transmission log mistake
The often pollution by a variety of noises in journey.In addition, certain links in image procossing when the picture object inputted and are not so good as pre-
Also noise can be introduced when thinking in result images.These noises often show as one on the image and cause the isolated of stronger visual effect
Pixel or block of pixels.Generally, noise signal it is uncorrelated to the object to be studied it occur with useless message form, upset figure
The observable information of picture.For data image signal, psophometer is either large or small extreme value, these extreme values are acted on by plus-minus
On the true gray value of image pixel, cause bright, dim spot to interfere image, greatly reduce picture quality, influence image restoration,
The progress of the subsequent work such as segmentation, feature extraction, image recognition.The filter for constructing a kind of effectively inhibition noise must be taken into consideration
Two basic problems: the noise that can be effectively removed in target and background；Meanwhile can protect well image object shape,
Size and specific geometry and topological features.
Using the automatic reporting system of auto parts state of the invention, it is not easy for rain brush position in the prior art as car owner
Observation and its integrity degree are difficult to the technical issues of detecting, are analyzed by the rain brush integrity degree to tempered glass surface,
To determine that rain brush whether there is incomplete problem, more it is essential that using trigger mechanism when swiping cacophonia, figure is avoided
As the waste of shooting and process resource；High-precision detection is carried out to salt-pepper noise point by the way of two-stage confirmation, wherein will be grey
The pixel that angle value is 0 or 255 is determined as spiced salt initial survey pixel, executes following processing to each spiced salt initial survey pixel:
The each vicinity points for determining each direction in all directions around it determine each of its gray value and each direction
The absolute value of the gray value mean value of vicinity points will choose the smallest absolute value of numerical value as ginseng in the absolute value of all directions
Value is examined, when the reference value is greater than preset difference value threshold value, determines that it is spiced salt confirmation pixel；Only salt-pepper noise is filtered
Wave processing, particular, it is important that the grey value profile situation based on the pixel of all directions around salt-pepper noise selects difference
Filter patterns；To solve above-mentioned technical problem.
It is understood that although the present invention has been disclosed in the preferred embodiments as above, above-described embodiment not to
Limit the present invention.For any person skilled in the art, without departing from the scope of the technical proposal of the invention,
Many possible changes and modifications all are made to technical solution of the present invention using the technology contents of the disclosure above, or are revised as
With the equivalent embodiment of variation.Therefore, anything that does not depart from the technical scheme of the invention are right according to the technical essence of the invention
Any simple modifications, equivalents, and modifications made for any of the above embodiments still fall within the range of technical solution of the present invention protection
It is interior.
