According to the application, the embodiment provides a parking space identification method. Optionally, in this embodiment of the present application, the parking space identification method may be applied to a hardware environment formed by the terminal 101 and the server 102 as shown in fig. 1. As shown in fig. 1, a server 102 is connected to a terminal 101 through a network, and may be used to provide services (such as application services) for the terminal or a client installed on the terminal, and a database may be provided on the server or separately from the server, and may be used to provide data storage services for the server 102, where the network includes but is not limited to: the terminal 101 is not limited to a PC, a mobile phone, a tablet computer, and the like.

The terminal 101 executes the parking space recognition method according to the embodiment of the present application, or may be executed by a client installed thereon.
Taking the example of the method for identifying a parking space performed by the terminal according to the embodiment of the present application as an example, fig. 2 is a schematic flow chart of an optional method for identifying a parking space according to the embodiment of the present application, and as shown in fig. 2, the flow of the method may include the following steps:
step 201, obtaining an engineering drawing to be identified, wherein the engineering drawing comprises a parking space layer, layer information of the parking space layer and graphic information in each parking space layer.
In some embodiments, the engineering drawing to be identified is an engineering drawing including a parking space map layer, such as a parking space drawing for community construction, a parking space drawing for mall construction, and the like. Or, the engineering drawing to be identified may also be an engineering drawing obtained by screening the original engineering drawing.
The original engineering drawing may be a construction drawing used for any engineering construction, such as a community construction drawing, a mall construction drawing, and the like.
The format of the engineering drawing may be, but is not limited to, a CAD format. Engineering drawings are often laid layer by layer according to layers during design, for example, different layers are used among different buildings, different layers are used during building and parking space design, corresponding layer information is configured for each layer to clarify contents included in the drawings, for example, the layer information is a parking space layer, a No. 1 building layer, a public facility layer and the like, and correspondingly, a design scheme corresponding to the layer information is drawn in each layer through graphic information.
In an optional embodiment, acquiring the engineering drawing to be identified includes:
acquiring an initial engineering drawing, wherein the initial engineering drawing comprises initial layer information of each layer; extracting a first layer name in the initial layer information; and screening the layer with the first layer name including the preset keyword in the initial engineering drawing to obtain the engineering drawing to be identified.
In some embodiments, the map-layer information often indicates content included in the map-layer, and after the engineering drawing to be identified is obtained, a parking space map layer including parking space information can be determined from the map-layer information in the engineering drawing.
Usually, the map layer information exists in a text form, so that a first map layer name can be extracted from the map layer information, and whether the map layer is a parking space map layer is determined by judging whether the first map layer name includes a preset keyword, where the preset keyword may be, but is not limited to, a parking space.
Exemplarily, a first layer name in the layer information is a charging parking space layer, and after the charging parking space layer is extracted, the charging parking space layer is compared with a "parking space", so that it can be known that the charging parking space layer includes a "parking space", and therefore, the charging parking space layer is determined to be the parking space layer.
In some embodiments, after a parking space layer in an engineering drawing is determined, because the parking space layer mainly includes parking space information, and when the parking space information is designed in the engineering drawing, an outer frame, a stop and the like of a parking space are often designed in the form of a pattern block, a serial number of the parking space is often designed in the form of characters, and the layer information indicates the type of the parking space in the layer. Therefore, the parking space information of the parking space layer can be determined according to the graphic information and the layer information in the parking space layer.
In some embodiments, the graphic information in each parking space layer is used for drawing a parking space, and therefore, after the parking space layer is determined, the contour information of the parking space and the orientation information of the parking space can be determined according to the graphic information in the parking space layer.
Specifically, the graphic information includes image blocks and graphic elements, the parking spaces usually exist in the form of parking space image blocks, and part of the information of a small number of parking spaces may also exist in the form of graphic elements of lines or multiple lines. A parking space may contain one or more tiles.
In an optional embodiment, the graphic information includes a graphic block, and the contour information of the parking space in the engineering drawing is determined according to the graphic information, including:
identifying contour information of each image block in the graphic information; if the contour information of the image block meets a first preset condition, determining that the contour information of the image block is the contour information of the parking space, wherein the first preset condition comprises that the shape information in the contour information is rectangular and the size information in the contour information is larger than a first preset size threshold value.
In some embodiments, the parking space exists in the form of the pattern block, and the size of the outline of the pattern block corresponding to the outer frame of the parking space is larger than the size of other pattern blocks. Therefore, the contour information of each pattern block is identified, the shape information in the contour information is a rectangle, the size information is larger than the pattern block with the first preset size threshold value, the pattern block is used as the pattern block corresponding to the outer contour of the parking space, and the contour information of the pattern block is used as the contour information of the parking space.
The first preset size threshold value can be set according to the size of the parking space in practical application, for example, the length is set to be 5 meters, and the width is set to be 2 meters.
In an optional embodiment, determining the orientation information of the parking space according to the graphic information includes:
acquiring target graphic information in the contour information of each parking space; determining the vehicle gear information and/or the parking space number in the contour information of each parking space according to the target graphic information; determining a first central point according to the car stop information and/or the parking space number; determining a second central point according to the contour information of the parking space; and determining the direction from the first central point to the second central point as the orientation information of the parking space.
In some embodiments, referring to fig. 3, the parking space frame often includes a car stop, a parking space number, and an identifier corresponding to a parking space type (e.g., a charging identifier, an unobstructed parking space identifier, etc.). Because the car bumper, the parking space number and the mark corresponding to the parking space type are all arranged in the parking space, the coordinate of the target graphic information corresponding to the information is in the contour information, and whether the graphic information is the target graphic information in the contour information of the parking space is judged by judging whether the coordinate of the graphic information in the image layer is in the contour information of the parking space.
And further, the parking position information and the parking position number in each parking position can be determined according to the target graphic information. In practical application, the car bumper and the parking space number are often arranged at the rear end of the parking space, and each graphic information has coordinate information, so that the first central point can be calculated through the coordinate information of the car bumper and the parking space number, and the second central point can be determined through the coordinate value of the outline information. Because car bumper and parking stall serial number are at the rear end of parking stall, consequently, the position of first central point is closer to the rear end of parking stall than the position of second central point, and then, regard the orientation information of parking stall as first central point to the direction of second central point.
In an optional embodiment, determining the car stop information and/or the car position number in the contour information of each car position according to the target graphic information includes:
determining character information in the target graphic information as a parking space number; and determining a target pattern block meeting a second preset condition in the target graphic information as the vehicle stop information, wherein the second preset condition comprises that the shape information of the target pattern block is rectangular and the size information of the target pattern block is smaller than a second preset size threshold.
In some embodiments, the identifier corresponding to the car stop and the parking space type exists in a pattern block form, and the parking space number exists in a text form, so that the car stop or the parking space number can be determined by judging the type of the target graphic information.
In practical application, the outline of the car bumper is far smaller than the outline of the parking space, so that when the target graphic information is a graphic block, whether the size information of the graphic block is smaller than a second preset size threshold value is judged, and if the size information of the graphic block is smaller than the second preset size threshold value, the target graphic block is determined to be the graphic block of the car bumper. Wherein, the second preset size threshold may be set to be, but not limited to, 0.4 meter long and 0.2 meter wide.
And step 203, determining the parking place type according to the layer information in the parking place layer.
In an optional embodiment, determining the parking space type according to the layer information of the parking space layer includes:
extracting a second layer name in the layer information of the parking space layer; matching the second map layer name with a preset parking place type set; and determining a target parking space type consistent with the name of the second map layer, wherein the target parking space type is the parking space type of the parking space in the parking space map layer, and the preset parking space type set comprises the target parking space type.
In some embodiments, when the map layer is drawn, not only the type of the map layer is written, but also the map layer of each type is further refined, for example, the parking space map layer respectively creates map layers for a common parking space, a primary-secondary parking space, an electric parking space, a barrier-free parking space and the like. Therefore, the name of the parking space type can be used as a preset parking space type set, and the preset parking space type set can include but is not limited to common parking spaces, primary and secondary parking spaces, electric parking spaces and barrier-free parking spaces. And matching the second layer name in the extracted layer with a preset parking place type set, and determining the type of the parking place according to a matching result if the matching is successful.
And step 204, identifying the parking spaces according to the contour information of the parking spaces, the orientation information of the parking spaces and the parking space types.
Based on the above-mentioned relevant embodiment, can confirm that the parking stall information in the engineering drawing includes the profile information of parking stall, the serial number of parking stall, the orientation of parking stall and the type of parking stall etc. bind and save above-mentioned parking stall information to carry out subsequent processing.

determining the direction information and the parking place type of the parking place corresponding to the contour information of each parking place; and taking the contour information of the parking spaces, the orientation information of the corresponding parking spaces and the parking space types as the information of the identified parking spaces.

Therefore, after the engineering drawing to be recognized is obtained, the type of the parking space, the contour information of the parking space and the orientation information of the parking space can be determined directly according to the graphic information and the layer information in the parking space layer, and the parking space information in the engineering drawing is determined, so that the purpose of recognizing the parking space is achieved, manual participation is not needed, the process of recognizing the parking space is more automatic, and the recognition efficiency is improved.
