Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 1 is a flowchart illustrating a method for determining a display status of a track section according to a first embodiment of the invention. The embodiment can be applied to the condition of effectively identifying the display states of different track sections based on the image identification technology. The method of the present embodiment may be performed by a device for determining a display status of a track segment, which may be implemented in hardware and/or software and may be configured in an electronic device. The method for determining the display state of the track section according to any embodiment of the present application can be implemented. As shown in fig. 1, the method specifically includes the following steps:
s110, acquiring the type of a track section to be identified in the track image; the type of the track section to be identified is a turnout section, a turnout-free section or a track section.
The rail for train running or parking in the railway station is divided into a plurality of areas with limited length, and each area is called a track section; the display status of the track section on the display is very important information for both the operator and the tester of the computer interlock system; the existing method for identifying the display state of the track section mainly relies on human eyes to directly watch the displayed color so as to identify the display state of the track section, but the method is easily influenced by environmental factors, so that the efficiency of identifying the display state of the track section is reduced, and manpower is also required to be consumed to complete the method.
Therefore, the present embodiment effectively recognizes the display states of different types of track sections by recognizing the track image using the image recognition technology; the track image is an image acquired by acquisition equipment in the testing process.
Wherein, the turnout section comprises 1-3 groups of turnouts; turnouts are not contained in the turnout sections and the track sections; the track section is longer in length and is used for parking an entire train; the turnout section is short in length and only can park 1-3 carriages.
And S120, determining an identification area of the track section to be identified according to the type of the track section to be identified.
In this embodiment, the identification area of the track segment to be identified is a fixed area formed by feature points in line segments in the track segment to be identified; and the width of the line segment is fixed (3 pixel points), therefore, the identification region in this embodiment may be a rectangular region of 3 × 3.
And S130, determining the display state of the track section to be identified according to the identification area.
In this embodiment, the color classification of the identification region may be determined according to the color range of the identification region, and the color of the track section to be identified is intuitively reflected according to the color of the identification region, so as to determine the display state of the track section to be identified; the display state of the track section to be identified is an occupied state, an idle state or a locking state; specifically, the occupancy state is represented by red; the idle state is indicated in blue; the locked state is indicated in white.
On the basis of the foregoing embodiment, optionally, determining the display state of the track segment to be identified according to the identification area includes:
acquiring a characteristic value of each pixel point in the identification area, and determining a display state value of the track section to be identified according to the characteristic value and a preset characteristic value;
and determining the display state of the track section to be identified according to the display state value of the track section to be identified.
In this embodiment, the feature value is a three-channel RGB value of the pixel point, and the overall display state of the corresponding segment can be obtained according to the RGB values of the similar points in the region. The preset characteristic value is an RGB value specified in the TJ/DW188-2016 station computer interlocking operation display technical specification; determining a display state value of the track section to be identified according to the characteristic value and the preset characteristic value may include: and if the ratio of the characteristic values of all the pixel points meeting the specification to the preset characteristic value exceeds a preset threshold value, taking the characteristic value as a display state value of the track section to be identified.
The display state value is (255 ) (indicating white), indicating that the display state of the track section to be identified is locked; the display status value is (255, 0) (indicating red), indicating that the display status of the track segment to be identified is occupied. In the embodiment, the characteristic values of the pixel points in the identification region are identified, so that the display state of the track section to be identified can be determined quickly and effectively.
The method comprises the steps of obtaining the type of a track section to be identified in a track image; the type of the track section to be identified is a turnout section, a turnout-free section or a track section; determining an identification area of the track section to be identified according to the type of the track section to be identified; and determining the display state of the track section to be identified according to the identification area. The embodiment of the invention carries out image recognition on the recognition area of the track section based on the image recognition technology, thereby realizing the automatic recognition of the display state of the track section.
Example two
Fig. 2 is a flowchart illustrating a method for determining a display status of a track section according to a second embodiment of the present invention. The embodiment is further expanded and optimized on the basis of the above embodiment, and can be combined with any optional options in the above technical solutions. As shown in fig. 2, the method includes:
s210, acquiring the type of a track section to be identified in the track image; the type of the track section to be identified is a turnout section, a turnout-free section or a track section.
S220, judging whether the type of the track section to be identified is a turnout section; if yes, go to S230; if not, go to S250.
In this embodiment, because the identification methods of the display states of the switch section and the turnout-free section (or the track section) are different, the type of the track section to be identified needs to be determined first, and then the identification needs to be performed by adopting different identification methods.
And S230, acquiring the position of a key turnout of the track section to be identified.
In this embodiment, the key switches are switches that have been calibrated in advance among all switches; wherein, the position of obtaining the key switch of the track section to be identified comprises: reading the characteristic data of the track section to obtain coordinate data (such as a start point coordinate and an end point coordinate) of a key area of each section, and storing the coordinate data in a turnout section coordinate data dictionary; and reading the position of the key turnout of the track section to be identified from the turnout section coordinate data dictionary. By storing the position information in advance, the relevant information can be quickly and accurately acquired when the position information is read.
And S240, determining an identification area of the track section to be identified according to the position of the key turnout.
In this embodiment, when the position of the switch is in the quarto position, the number of the identification areas of the track segment to be identified is at least two, which is intended to ensure that the color gradient area may affect the determination of the display value of the identification area at the connection; when the positions of the key turnouts are not located at the four-switch positions, the identification area of the track section to be identified can only select the turnout area of the key turnout.
And S250, determining the characteristic line segment of the track section to be identified according to the length of each line segment in the track section to be identified.
In the embodiment, a longer line segment in an image forming a turnout section or a track section is selected as a characteristic line segment, so that pixel points with enough data are ensured to be used for identification; the number of the characteristic line segments is at least two, namely two line segments formed according to the starting points and the end points of the characteristic line segments.
And S260, determining an identification area of the track section to be identified according to the characteristic line segment of the track section to be identified.
In the present embodiment, referring to fig. 3, fig. 3 is a diagram showing an identification area of a display state of a turnout-free section; selecting line segments with at least 3 pixels long at the starting point and the end point of the characteristic line segment to form 2 minimum 3 multiplied by 3 rectangular areas, and reading the RGB value of each pixel point in the two identification areas to realize the identification of the display state of the turnout sections with different shapes; wherein, the rectangular frame in fig. 3 can be enlarged to select the identification area; the dots are the demarcation points of different track sections.
And S270, determining the display state of the track section to be identified according to the identification area.
On the basis of the above embodiment, optionally, determining the identification area of the track section to be identified according to the position of the key switch includes:
if the key turnout is detected to be in the quarto position, determining a characteristic line section of the track section to be identified according to the length of the line section of the key turnout; the length of the line segment of the key turnout is the length of each line segment formed before and after the turnout of the key turnout;
and determining the identification area of the track section to be identified according to the characteristic line segment of the track section to be identified.
In the present embodiment, the switch section identification area is determined in a similar manner to the determination method of the turnout section or track section identification area; referring to the selection criteria for the turnout-free section, it can be found that, from the key turnouts at four switch positions, the longest line segment is selected as the characteristic line segment of the track section to be identified, and then the area formed by the starting point and the ending point of the characteristic line segment is used as the identification area of the track section to be identified. According to the embodiment, the display state of the track section to be identified can be reasonably and accurately reflected through the local point position in the characteristic line segment of the track section to be identified.
On the basis of the above embodiment, optionally, determining the identification area of the track section to be identified according to the position of the key switch includes:
if the key turnout is detected to be in a positioning position or a reverse position, acquiring the turnout center point coordinate of the key turnout;
and determining the identification area of the track section to be identified according to the frog point coordinates of the key turnout.
In this embodiment, for a switch in which a switch section is not located in a quarto position, one area may be selected as an identification area of a track section to be identified; the fork point coordinate is a display coordinate of the fork point in the graphical interface; referring specifically to fig. 4, fig. 4 is a diagram showing the identification areas of the turnout section display states; due to the position limitation of the turnout section, the color of the line segment contained in the key turnout is not converted by the connecting point, namely the color of the line segment is uniform and balanced, and then one point process identification area is selected. In order to make the colors in the identification regions uniform, the rectangular frame in fig. 4 should be enlarged to select the identification regions; the dots are the demarcation points of different track sections.
On the basis of the foregoing embodiment, optionally, determining the identification area of the track segment to be identified according to the characteristic line segment of the track segment to be identified includes:
calculating the slope of the characteristic line segment;
and determining the composition areas of the starting point and the end point of the characteristic line segment according to the slope of the characteristic line segment, and taking the composition areas as the identification areas of the track section to be identified.
In this embodiment, in order to make the obtained identification region regular, it is necessary to calculate the slope of the feature line segment to determine the identification region constructed by the start point and the end point of the feature line segment; the starting point coordinates and the end point coordinates of the characteristic line segments can be read from a coordinate data dictionary stored in advance; the coordinate data dictionary comprises a turnout section coordinate data dictionary, a turnout section coordinate data dictionary and a track section coordinate data dictionary. In the embodiment, the identification area formed by the starting point and the end point of the characteristic line segment is determined by the slope of the characteristic line segment, so that the determined identification area has higher regularity, and the accurate search of the characteristic value in the identification area is facilitated.
