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 of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of an auxiliary display method according to an embodiment of the present invention, where this embodiment is applicable to a case where an auxiliary display atlas with a higher resolution is obtained for a certain point of interest or an area of interest in a map selected by a user for auxiliary display, and the method may be executed by an auxiliary display device, where the auxiliary display device may be implemented by software and/or hardware, and may be generally integrated in a terminal or a server with data identification and processing functions, and specifically includes the following steps:

step 110, obtaining a map and displaying the map in a display interface, wherein the map has a first resolution;

in this embodiment, the map may be a three-dimensional map, an electronic map, a standard orthophoto map, and the like. Specifically, the three-dimensional map and the electronic map may be obtained from the outside, and the standard orthophoto map may be obtained from an orthophoto map library. The orthophoto library can store a plurality of orthophotos, and the orthophotos are stored in association with the shot geographic position range.

Optionally, when the user inputs a certain geographical location information or a certain geographical location range, the matched standard ortho-image may be obtained from the ortho-image gallery and displayed in the display interface. The standard orthophoto map may be a certain orthophoto map in an orthophoto map library, or may be a combined map of a plurality of adjacent orthophoto maps in the orthophoto map library, which is not limited in this embodiment.

Wherein, each orthophoto map in the orthophoto map storehouse can carry out the collection of aerial survey data to user's appointed area through aerial survey unmanned aerial vehicle and obtain. Typically, aerial survey unmanned aerial vehicle flies to in the appointed area to fly along preset round trip route at appointed height, and the high definition picture of vertical ground is shot to the equidistance during flight to guarantee that adjacent picture satisfies certain overlap. After the unmanned aerial vehicle obtains the picture, the unmanned aerial vehicle carries out air-to-three encryption processing to obtain a high-definition orthophoto map of a user-specified area, namely the orthophoto map. Accordingly, the standard orthophoto map has a first image resolution determined primarily by the flight height of the aerial drone and the camera parameters (e.g., camera focal length and image sensor pixel size, etc.) of the mapping camera used during the aerial.

The aerial photogrammetry method adopted by the unmanned aerial vehicle in the process of shooting the high-definition orthophoto map in the designated area is not limited in the embodiment of the invention, and only the high-definition orthophoto map data in the designated area can be obtained.

Step 120, determining an interest point or an interest area in the map;

in this embodiment, the user may select a rough viewing area in the map, and the manner of selecting the viewing area may be: a closed area is outlined in the map or at least one target point is selected. Optionally, in response to at least one target point selected in the map, the embodiment of the present invention may use the at least one target point as the interest point; the region of interest can also be determined in the map according to at least one target point selected in the map in response to the at least one target point; alternatively, the region of interest may be determined in the map according to the closed region in response to the closed region selected in the map.

In a specific example, after detecting that a user selects a target point in a map, the target point may be directly used as an interest point, or a circle may be generated by setting a length value as a diameter with the target point as a center of a circle, or a square may be generated by setting a length as a side length with the target point as a center, or a center point obtained by weighting and summing a plurality of target points may be used as an interest point after detecting a plurality of target points selected by the user in the map.

In another specific example, after it is detected that the user selects a closed region in the map, the minimum circumscribed circle or the minimum circumscribed rectangle of the closed region may be used as the region of interest, and the like.

Step 130, at least one auxiliary display atlas matching the point of interest or the region of interest is obtained, the auxiliary display atlas having a second resolution, the second resolution being higher than the first resolution.

In view of the problem of low resolution of the map in the prior art, in the present embodiment, it is proposed to display the map in a complementary manner by using at least one auxiliary display atlas matched with the interest point or the interest area. The auxiliary display map set comprises one or more auxiliary display maps, and the second resolution of the auxiliary display maps is higher than the first resolution. Alternatively, the auxiliary display album may be an album obtained by filtering out photographic albums each including at least one photographic image taken at a set shooting point. Accordingly, obtaining at least one auxiliary display atlas that matches the point of interest may be: calculating relative distance values between the shooting points of the shooting atlas and the interest points, and screening out the shooting atlas corresponding to one or more shooting points with the relative distance value closest to the interest points as the auxiliary display atlas; alternatively, the relative distance values may be considered, and the position distribution of each shooting point and the interest point may be further considered, for example, in a plane parallel to the ground plane where the interest point is located, a coordinate system is configured with the interest point as a center, and at least one shooting map set corresponding to the shooting point with the smallest relative distance value is acquired as the auxiliary display map set in each of four quadrants of the coordinate system.

Alternatively, the obtaining of the at least one auxiliary display atlas matched with the region of interest may be: in each pre-stored photographic picture set, acquiring a first target photographic picture set with a shooting point located in the region of interest, wherein the first target photographic picture set comprises at least one photographic picture shot under a set shooting point; and determining the auxiliary display atlas according to the first target photography atlas. Specifically, according to the first target photograph album, the manner of determining the auxiliary display album may be: all the first target radiographs are set as the auxiliary display atlas, or the auxiliary display atlas is selected from all the first target radiographs according to a set selection condition (for example, a distance condition or an angle condition), and the like. The method may further include acquiring a plurality of camera albums of the second resolution from the third party platform by means of interface calling, and screening out at least one auxiliary display album matching the point of interest or the region of interest from the plurality of camera albums, or may also include generating a plurality of camera albums of the second resolution in advance, and storing the plurality of camera albums of the second resolution in a camera album database. After the interest point or the interest area is determined, an auxiliary display atlas matched with the interest point or the interest area is obtained directly from the photographic atlas database. In this embodiment, the oblique photography atlas in the designated area acquired by the multi-lens oblique photography technique may be stored in the photography atlas database in advance, and then the corresponding auxiliary display atlas may be screened out based on the oblique photography atlas stored in the photography atlas database.

Specifically, when the oblique photography atlas is generated, the multi-lens oblique photography aerial survey unmanned aerial vehicle can be used for carrying out ground-imitating mode flight on the designated area in a round trip flight path mode, and high-definition images are synchronously acquired through one vertical visual angle and four oblique visual angles. Different shot points correspond to different oblique photography picture sets, and each oblique photography picture set comprises: a standard orthographic view matched with the shot point and a synchronous acquisition view in four oblique directions. Therefore, the oblique photography atlas obtained through collection can obtain rich high-resolution textures of the top surface and side view of the building, and the oblique photography atlas not only can truly reflect the ground feature condition, but also can obtain the ground feature texture information with high precision.

In a specific manner of this embodiment, in which oblique photography albums are screened to obtain an auxiliary display album, all oblique photography albums whose shooting points fall within an area of interest may be screened as the auxiliary display album, one or more oblique photography albums closest to an actual object may be screened as the auxiliary display album in each oblique photography album whose shooting points fall within the area of interest, and further, in an oblique photography album, a synchronous acquisition image in a specific oblique direction may be screened to generate the auxiliary display album, and the present embodiment is not limited thereto.

Optionally, the determining the auxiliary display atlas according to the first target photography atlas includes: screening out at least one second target photographic atlas from the first target photographic atlas according to the position relationship between the shooting point of each first target photographic atlas and a target fixed point in the region of interest (for example, the shooting point can be the central point of the region of interest, or a boundary point or a point on a perpendicular bisector, and the like); and screening the photographic images included in each second target photographic image set to generate auxiliary display image sets respectively corresponding to each second target photographic image set. The photographic atlas includes: in the process of flying along a set route, shooting at a set shooting point to obtain an oblique photography atlas; the oblique photography atlas includes: a standard orthographic view matching the shot point and at least one simultaneous acquisition view in an oblique direction.

And 140, displaying the at least one auxiliary display atlas in the display interface.

In this step, at least one auxiliary display atlas is displayed in the same display interface synchronously with the map, so that a user can further observe the content displayed in the map by combining the auxiliary display atlas with high resolution. Optionally, the map may be displayed in the center of the display interface, at least one auxiliary display atlas may be displayed around the map, or at least one auxiliary display atlas may be displayed in a drop-down or slide-across list on one side of the map.

The method of the embodiment of the invention can be executed by an application program (APP) client installed in a terminal (mobile terminal or PC and the like) device. In one specific example, a user may first trigger map data on an APP that is responsive to geographic location information entered in the map data, and then retrieve a map (typically, a standard orthophotomap) that matches the geographic location information for display in a display interface.

and 310, acquiring a map and displaying the map in a display interface, wherein the map has a first resolution.

Step 320, determine a point of interest or a region of interest in the map.

Step 330, in each pre-stored oblique photography atlas, acquiring at least one first target oblique photography atlas with a shooting point located in the region of interest, where the oblique photography atlas includes: a standard orthographic view matching the shot point and at least one simultaneous acquisition view in an oblique direction.

In the step, the multi-lens oblique photography aerial survey unmanned aerial vehicle carries out high-definition image acquisition in advance according to map data, acquires a standard orthographic view of at least one shooting point and synchronously acquires images in at least one oblique direction and prestores the images into oblique photography image sets matched with the shooting points. The embodiment of the invention selects the oblique photography atlas with the shooting point positioned in the region of interest of the user as the first target oblique photography atlas.

And 340, determining a first diameter and a second diameter according to the route distance used for shooting each oblique photography atlas, and determining a first circle matched with the first diameter and a second circle matched with the second diameter in the map according to the target fixed point, the first diameter and the second diameter, wherein the first diameter is smaller than the second diameter.

In this step, as shown in fig. 4, selecting a middle point of an area 401 of interest as a target fixed point, taking the target fixed point 402 of the area 401 of interest as a center of a circle, acquiring the route distance of 0.9 times as the first diameter, and determining a first circle 403 in the map; and taking the target fixed point 402 as a circle center, acquiring the route distance of 2.5 times as the second diameter, and determining a second circle 404 in the map. It should be noted that, in this embodiment, the first diameter is selected to be 0.9 times the lane pitch, and the second diameter is selected to be 2.5 times the lane pitch, which is a specific value selected by the inventor according to an actual use situation, and a technician in this embodiment may freely set the first diameter or the second diameter according to the actual situation, which is not limited in this embodiment.

And 350, in each first target oblique photography atlas, acquiring a first class oblique photography atlas with a shooting point positioned in the first circle as the second target oblique photography atlas, and acquiring a second class oblique photography atlas with a shooting point positioned in an annular ring enclosed by the first circle and the second circle.

In this step, the oblique photography atlas corresponding to all the photographing points in the region of interest 401 is the first target oblique photography atlas, the oblique photography atlas corresponding to the photographing point in the first circle 403 is the first type oblique photography atlas, the first type oblique photography atlas belongs to the second target oblique photography atlas, the oblique photography atlas corresponding to the photographing point in the circle formed by the first circle 403 and the second circle 404 is the second type oblique photography atlas, and the photographing point corresponding to the second type oblique photography atlas is the second type oblique photography photographing point.

And 360, screening a set number of second oblique photography albums as the second target oblique photography album according to the sequence of the shooting point distance from the target fixed point from small to large.

The set number value may be preset according to actual conditions, for example, 2, 4, or 6, and in the present embodiment, the set number is set to 4 for example. In this step, as shown in fig. 4, 4 second-type

oblique photographing points

405, 406, 407, and 408 closest to the target fixed point 402 are selected in the order of increasing distance from the target fixed point 402 to the second-type oblique photographing point.

Step 370, obtaining auxiliary display atlas corresponding to the first class oblique photography atlas and the second class oblique photography atlas respectively.

In the present embodiment, the oblique photographic image set includes a standard orthographic image of shot point matching and synchronous acquisition images in four oblique directions. Alternatively, the first oblique photograph album and the second oblique photograph album may be directly used as the auxiliary display album, or the auxiliary display album may be generated after the first oblique photograph album and the second oblique photograph album respectively screen out oblique photographs that obviously do not photograph the feature to be displayed. Optionally, obtaining an auxiliary display atlas corresponding to the first class oblique photography atlas may include: and respectively acquiring a standard orthographic picture as the auxiliary display picture set in each first type oblique photograph picture set.

Specifically, as shown in fig. 4, the shooting points corresponding to the first oblique photography atlas are the shooting points in the first circle 403, which are also called as first oblique photography shooting points, and an ortholens photograph (i.e., a standard orthoview) corresponding to the first oblique photography shooting points is obtained as the auxiliary display atlas. Since the oblique lens of oblique photography has a certain photographing blind area right below the photographing point, when the photographing point exists in the first circle 403, the target fixed point 402 can be considered to be in the oblique photographing blind area of the first type oblique photographing point, so that the oblique photographing picture of the first type oblique photographing point is excluded, only the ortholens picture of the first type oblique photographing point is reserved, and the ortholens picture is taken as the auxiliary display atlas.

In this step, acquiring an auxiliary display atlas corresponding to the second-type oblique photography atlas includes:

s3701, acquiring target shooting points and the inclination directions of all target synchronous acquisition graphs relative to the target shooting points according to the currently processed second-class oblique photography atlas;

the aerial survey orthophoto image in the prior art can only observe ground objects on the ground through an overlooking angle, has limitation in use, and cannot visually and completely observe the shape and size of the ground objects when the ground objects are vertically shielded, so that an oblique photography picture corresponding to a shooting point closest to the ground objects, namely a target shooting point, needs to be screened out to comprehensively observe information of the ground objects.

Specifically, as shown in fig. 4, the shooting points corresponding to the second oblique photography atlas are shooting points in a circle surrounded by a first circle 403 and a second circle 404, which are also referred to as second oblique photography shooting points, and according to the order from the second oblique photography shooting points to the target fixed point 402, 4 second oblique photography shooting points 405, 406, 407, and 408 closest to the target fixed point 402 are screened out as target shooting points, and for each second oblique photography atlas, an orthophoto lens picture corresponding to the shooting point, that is, a standard orthophoto map, and pictures in four oblique shooting directions, that is, synchronous acquisition maps are acquired at each target shooting point, wherein each synchronous acquisition map has a set oblique direction relative to the target shooting point. In this embodiment, taking the second-type oblique-view atlas corresponding to the shooting point 405 as the currently processed second-type oblique-view atlas, how to determine the auxiliary annotation atlas corresponding to the currently processed second-type oblique-view atlas will be specifically described. The process of determining the corresponding auxiliary annotation map set in the second oblique photograph map sets corresponding to the other photograph points (the photograph points 406, 407 and 408) is substantially the same as the process, and will not be described herein again. Therefore, based on the currently processed second-type oblique photography atlas, the target shooting point corresponding to the second-type oblique photography atlas is acquired first, and the inclination direction of each target synchronous acquisition atlas relative to the target shooting point is acquired.

S3702, establishing a connecting line between the target shooting point and the target fixed point, and generating an inclined included angle between each target synchronous acquisition graph and the midpoint of the area according to the inclined direction of each target synchronous acquisition graph; specifically, as shown in fig. 5, taking the target shooting point 405 as an example, a connection line between the target shooting point 405 and the target fixed point 402 is established, and the four oblique directions of the target shooting point synchronous acquisition diagram are 409, 410, 411, and 412, respectively, an included angle between the connection line between the target shooting point 405 and the target fixed point 402 and the connection line between the target shooting point 405 and the four oblique directions is generated, and the included angle is taken as an oblique included angle of the target synchronous acquisition diagram of the target shooting point 405 relative to the target fixed point 402.

And S3703, acquiring the target standard orthographic picture and a target synchronous acquisition picture with the inclination included angle meeting the set angle threshold value condition, and taking the target synchronous acquisition picture as an auxiliary display picture set corresponding to the currently processed second-type oblique photography picture set. Specifically, by comparing the sizes of the oblique angles, a target synchronous acquisition map having an oblique angle satisfying a predetermined angle threshold condition (for example, a target synchronous acquisition map having a minimum oblique angle or a target synchronous acquisition map having an oblique angle smaller than 30 degrees) is selected together with a target standard orthographic map corresponding to the second oblique photography atlas to be processed currently, and an auxiliary display atlas corresponding to the second oblique photography atlas is constructed. Specifically, only one target synchronous acquisition map with the smallest tilt angle may be selected from the second oblique photograph album to be processed together with the target normal orthographic map, so as to generate the auxiliary display album corresponding to the second oblique photograph album.

And 380, synchronously displaying the at least one auxiliary display atlas in the display interface.

In this step, at least one auxiliary display atlas is displayed in the same interface in synchronization with the map, so that the user can accurately observe the actual position and shape of the ground object.

Firstly, obtaining a map and displaying the map in a display interface, and determining an interest point or an interest area in the map; then, a first circle and a second circle are determined according to a target fixed point, four target shooting points are determined by comparing the distance between a shooting point in a circular ring enclosed by the first circle and the second circle and the target fixed point, a connecting line between the target shooting point and the target fixed point is established, an inclined included angle of a graph relative to the target fixed point is synchronously acquired by comparing the target shooting points, an optimal inclined shooting picture corresponding to the target shooting point is screened out, and the optimal inclined shooting picture, a standard orthographic graph of the target shooting point and a standard orthographic graph corresponding to the first circle are used as an auxiliary display graph set; and finally, synchronously displaying the at least one auxiliary display atlas in a display interface. According to the embodiment of the invention, the farmland ground objects are observed with multi-view and high-definition effects, the optimal inclined pictures of the ground objects with multi-view angles are screened out, and the user can accurately identify the shape and the size of the ground objects and the corresponding positions.
