And S22, when the driving attribute is determined to be a single-lane, associating the image set with the independent display slot position at the corresponding navigation position based on the shooting position, and obtaining an independent image set corresponding to the independent display slot position.
It can be understood that when the server determines that the driving attribute is a single-lane, the server directly correlates the image set with the independent display slot position at the corresponding navigation position according to the shooting position, so as to obtain an independent image set corresponding to the independent display slot position.
It is easy to understand that when the vehicle is a single-way lane, only scenic images in one direction are needed to be displayed at the moment, so that the image set is directly associated with the independent display slot corresponding to the navigation position according to the shooting position, and the subsequent selection display is facilitated.
S23, when the running attribute is determined to be a double-lane, a running starting point and a running end point of a shooting end are collected, and a running direction corresponding to the shooting end is determined based on the running starting point and the running end point.
It will be understood that when the server determines that the driving attribute is a dual-lane, the corresponding driving direction is determined according to the driving start point and the driving end point of the photographing end, for example, from a to B, the driving direction is a right-side road (from north to south), from B to a, and the driving direction is a left-side road (from north to south), and it will be understood that in practice, the driving directions of the dual-lane are different, and one is a left-side road and the other is a right-side road.
S24, classifying the image sets according to the driving directions to obtain a left driving set corresponding to the left display area and a right driving set corresponding to the right display area.
It can be appreciated that the server classifies the image sets according to the driving direction to obtain a left driving set corresponding to the left display area and a right driving set corresponding to the right display area.
It is easy to understand that the scenic images in the image sets shot by the vehicles running on the left road are classified into the left running sets corresponding to the left display areas, and the scenic images in the image sets shot by the vehicles running on the right road are classified into the right running sets corresponding to the right display areas, so that the subsequent image updating of corresponding directions is convenient for different display areas.
And S3, selecting scenic images in the image set according to a quality selection strategy to obtain updated images, and updating the corresponding scene display slots at regular time based on the updated images to generate a guide road section corresponding to the travel road section.
It can be understood that the server can select the scenic images in the image set according to the quality selection policy so as to obtain updated images, and in the above manner, the scenic images with higher scenic occupancy in the image set are selected as updated images for subsequent update display.
Further, the server updates the corresponding scene display slots at regular time according to the updated images, so as to generate the guide road sections corresponding to the travel road sections.
In some embodiments, in step S3 (selecting scenic images in the image set according to a quality selection policy to obtain updated images, and updating the corresponding scene display slots in a timing manner based on the updated images to generate a tour segment corresponding to the tour segment), the method includes S31-S32:
s31, selecting scenic images in the independent image set according to a quality selection strategy, or selecting scenic images in the left driving set and the right driving set to obtain updated images.
It will be appreciated that the server may choose the scenic images in the independent image set according to a quality selection policy, or choose scenic images in the left-hand running set and the right-hand running set, to obtain updated images.
It is easy to understand that image screening is performed on the image set corresponding to each navigation point according to the quality selection strategy, and the image set with higher scene occupation is selected as an updated image, so that the subsequent user can watch conveniently.
In some embodiments, in step S31 (selecting scenic images in the independent image set according to a quality selection policy, or selecting scenic images in the left-side driving set and the right-side driving set to obtain updated images), S311-S314 are included:
s311, carrying out vehicle contour recognition on scenic images in the independent image set or the left driving set and the right driving set based on OpenCV to obtain a plurality of vehicle contours in each scenic image.
It can be understood that the OpenCV is used for identifying the vehicle contour of the scenic spot image in the independent image set or the left driving set and the right driving set, and it is not difficult to understand that the OpenCV in the prior art can be used for identifying the vehicle contour in the image, so as to obtain a plurality of vehicle contours in each scenic spot image.
S312, obtaining pixel points in the vehicle outline in each scenic image as vehicle pixel points, and taking the rest pixel points as scenic pixel points.
It can be understood that after obtaining a plurality of vehicle outlines in each scenic image, the pixels inside the vehicle outlines are taken as vehicle pixels, and the other pixels are taken as scenic pixels.
S313, determining the number of all the scenery pixels in the scenery image to obtain scenery number, determining the number of all the pixels in the scenery image to obtain total number, and determining the scenery score according to the ratio of the scenery number to the total number.
It can be appreciated that determining the number of all the scenery pixels in the scenery images results in a scenery number, wherein the scenery number is the number of all the scenery pixels in each scenery image.
Further, the total number of all pixel points in the scenic image is determined, and the scenic score is determined according to the ratio of the scenic number to the total number. It is easy to understand that the scene score is the ratio of the number of the scene pixels to the number of all pixels in the scene image, and the higher the ratio is, the more the scene part in the scene image is, the better the quality is, and the lower the ratio is, the less the scene part in the scene image is, and the quality is poor.
S314, sorting all the scenery images in the independent image set or the left driving set and the right driving set in a descending order based on the scenery scores to obtain an image sequence, and selecting a first scenery image in the image sequence as an updated image.
It will be appreciated that the individual images or the scenery images in the left and right running sets are sorted in descending order by scenery scoring to obtain an image sequence, and it will be appreciated that the better the quality of the image sequence, the more front the sorting, and therefore the server will pick the first scenery image in the image sequence as an updated image.
It is easy to understand that, because scenic shooting is performed on the tourist highway, there may be situations that other vehicle license plates exist in the shot image, so after the updated image with better quality is selected, the license plates in the updated image are further covered, thereby protecting privacy.
On the basis of the embodiment, the method further comprises B1-B5:
and B1, acquiring license plate pixel values of a vehicle license plate, and counting adjacent pixel points which are the same as the license plate pixel values in the updated image to obtain a plurality of to-be-screened sets corresponding to the updated image.
It can be understood that the server may obtain the license plate pixel values corresponding to the license plate of the vehicle, for example, blue and black, and it is easy to understand that the license plate pixel values are preset in advance according to the actual situation.
Further, the server may count the pixels in the updated image, which are the same as the license plate pixels and are adjacent to the license plate pixels, and may obtain a plurality of sets to be screened by counting all adjacent license plate pixels.
And B2, determining the number of pixel points in each set to be screened to obtain the number to be screened, and reserving the set to be screened, of which the number to be screened is smaller than the preset screening number, to obtain a plurality of sets to be compared.
It should be noted that, since the scenic image has the rest pixels with the same pixel value as the photographed pixels, the invention needs to screen the set to be screened, and since the license plate of the vehicle is smaller, the area occupation ratio in the image is not too large, and the number of the corresponding pixels is smaller.
Therefore, the server determines the number of the pixel points in each set to be screened to obtain the number to be screened, and reserves the set to be screened, the number of which is smaller than the preset screening number, to obtain a plurality of comparison sets.
According to the embodiment, the large-occupied-area filtering is performed, only the to-be-filtered set with the small area is reserved as the to-be-compared set, and the problem that the vehicle license plate is far and near in the picture is considered, so that the corresponding area can be large or small, but due to the fact that the license plate is small, a user can set the largest preset filtering quantity according to actual conditions, the area filtering is performed, and the obviously larger areas are filtered, so that the processing capacity of subsequent data processing is reduced, and the license plate of the vehicle is better extracted.
And B3, carrying out contour recognition on each set to be compared based on OpenCV, and reserving rectangular contours to obtain a plurality of rectangular frames.
It should be noted that OpenCV is a powerful computer vision library, and main functions include image processing, computer vision, and the like, and can identify and screen contours in images, so that the invention can identify contours of corresponding areas of each set to be compared in the images through OpenCV.
Therefore, the method and the device can identify the outline of the corresponding area of each set to be compared based on OpenCV, and only the rectangular outline is reserved, so that a plurality of rectangular frames are obtained.
And B4, acquiring the actual duty ratio of the length and the width of each rectangular frame, taking the rectangular frame with the actual duty ratio being consistent with the preset duty ratio as a license plate frame, and selecting the area where the license plate frame is positioned as a covering area.
The aspect ratio of the license plate is fixed, and the length and width of the license plate are 440mm×140mm.
Therefore, the server obtains the actual duty ratio of the length and the width of each rectangular frame, and takes the rectangular frame with the same actual duty ratio as the preset duty ratio as the license plate frame, wherein the preset duty ratio is the duty ratio obtained according to the ratio of the length and the width of the license plate of the vehicle. The corresponding actual duty ratio can be obtained by counting the ratio of the number of pixels in the length direction to the number of pixels in the width direction in each rectangular frame, or other prior art can be adopted, and the method is not limited herein.
Furthermore, the area where the license plate frame is located is selected as a covering area, so that subsequent covering is facilitated.
And B5, covering the covering area in the updated image based on a preset covering layer to obtain a display image.
It may be appreciated that the server may cover the covering area in the updated image based on a preset covering layer, so as to obtain the display image, where the preset covering layer may be a preset mosaic image, and is not limited herein.
And S32, updating the corresponding scene display slots at regular time based on the updated images, and generating a guide road section corresponding to the travel road section.
It can be appreciated that when the server picks out the updated image with better quality, the scene display slots corresponding to the scene display slots are updated at regular time based on the updated image, so as to generate the tour road section corresponding to the tour road section.
Through the embodiment, the scenic images at the navigation points are updated at regular time, so that the user can attach to the actual situation when looking over, and the use experience of the user is improved.
S4, receiving an access request of an access terminal, and sending the navigation road section to the access terminal for display based on the access request.
On the basis of the embodiment, the method further comprises C1-C2:
and C1, receiving a locking display image and a locking display time period which are configured for the scene display slot by the management end.
It can be understood that the server receives the locked display image configured by the management end for the corresponding scene display slot and the locked display time period corresponding to the locked display image. The locking display image is a display image set by the management end, the locking display time period is a time period for displaying the locking display image, and the corresponding locking display image in the time period cannot be updated and replaced.
It is easy to understand that when an administrator finds that the image quality at the scene display slot is poor, the administrator can actively configure a corresponding locking display image for the scene display slot and configure a corresponding locking display time period for the locking display image, so that only the locking display image is displayed in the locking display time period and cannot be updated and replaced.
And C2, locking and displaying the locking display images in the corresponding scene display slots in the guide road section in the locking display time period.
