Obviously, those skilled in the art can obtain other drawings according to these drawings without any creative effort.

[0083] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present disclosure, not all the embodiments.

[0084] At present, only planar data of an object can be extracted in a high-precision map, such as two-dimensional coordinates of the object, and height data of the object is lacking. For example, a road portal, a sign, a road sign, and a road barrier all need to have height data, so as to facilitate accurate judgment of scene information.

[0085] Based on this, the disclosure provides a simulation scene construction method and device, electronic equipment and medium. The position information and type information of the entity in the target data are obtained by data analysis of the target data, and the three-dimensional model of the entity is determined according to the position information and type information of the entity, so as to restore the height of the entity with missing height information, expand the three-dimensional information of the entity, and effectively construct the target simulation scene according to the position information of the entity and the three-dimensional model of the entity, so as to intuitively and effectively identify the scene where the entity is located.

[0086] Specifically refer to Figure 1 exemplarily shown in the figures.

[0087] Figure 1 is a flowchart of a simulation scene construction method provided by an embodiment of the disclosure. The embodiment method can be executed by a simulation scene construction device, which can be realized in hardware and / or software, and can be configured in an electronic device. The simulation scene construction method described in any embodiment of the present application can be realized. As shown in the figure, the method specifically includes the following: Figure 1

[0088] S110, obtaining target data.

[0089] The target data is the data of the entity in the local area of the map.

[0090] The target data can be obtained from a high-precision map, and the target data can be displayed in the form of a data model.

[0091] The entity can be one or more objects with missing height data in the local area of the map.

[0092] The target data can be the data of all entities existing in one or more local areas included in the high-precision map, or can be the data of part of the entities existing in one or more local areas included in the high-precision map.

[0093] It should be noted that the all entities / part of the entities mentioned above can include entities with missing height data in the high-precision map, such as flagpoles, traffic lights, speed bumps, traffic signs, etc.

[0094] S120, analyzing the target data to obtain the position information and type information of the entity in the target data.

[0095] The type information of the entity can include multiple types, such as a first type and a second type, the first type can correspond to a geometric solid figure, and the second type can correspond to a column figure, and the disclosure does not limit the specific type of the type information of the entity.

[0096] ​The position information of the entity corresponds to the type information of the entity, that is, the position information of different entities corresponding to the type information is different.

[0097] For example, when the type information of the entity is a geometric solid figure, the position information of the entity can include two-dimensional coordinates of the entity, such as lower surrounding surface boundary coordinates, lower surrounding surface contour coordinates, etc.; when the type information of the entity is a cylinder figure, the position information of the entity can include two-dimensional coordinates and a radius of the entity, wherein the two-dimensional coordinates can include a center point coordinate of an upper surrounding surface corresponding to the entity and a center point coordinate of a lower surrounding surface corresponding to the entity, and the radius can include a radius of the upper surrounding surface and a radius of the lower surrounding surface.

[0098] The geometric solid figure can include a cuboid, a cube, etc., which are not limited in the present disclosure.

[0099] It should be noted that the center point coordinate of the upper surrounding surface corresponding to the entity can be the same as the center point coordinate of the upper surrounding surface corresponding to the entity, and the radius of the upper surrounding surface can be the same as the radius of the lower surrounding surface, and the entity at this time can be regarded as a cylinder perpendicular to the ground.

[0100] Alternatively, the center point coordinate of the upper surrounding surface corresponding to the entity can be different from the center point coordinate of the upper surrounding surface corresponding to the entity, and the radius of the upper surrounding surface can be the same as the radius of the lower surrounding surface, and the entity at this time can be regarded as a cylinder inclined to the ground.

[0101] Alternatively, the center point coordinate of the upper surrounding surface corresponding to the entity can be the same as the center point coordinate of the upper surrounding surface corresponding to the entity, and the radius of the upper surrounding surface can be different from the radius of the lower surrounding surface, and the entity at this time can be regarded as a circular truncated cone perpendicular to the ground.

[0102] Alternatively, the center point coordinate of the upper surrounding surface corresponding to the entity can be different from the center point coordinate of the upper surrounding surface corresponding to the entity, and the radius of the upper surrounding surface can be different from the radius of the lower surrounding surface, and the entity at this time can be regarded as a circular truncated cone inclined to the ground.

[0103] S130, determining a three-dimensional model of the entity according to the position information and the type information of the entity.

[0104] The three-dimensional model of the entity is a model with three-dimensional information of length, width and height, which can effectively restore the real form of the entity.

[0105] When the type information of the entity is a geometric solid figure, the length of the entity can be the length of the figure corresponding to the lower surrounding surface of the geometric solid figure, the width can be the width of the figure corresponding to the lower surrounding surface of the geometric solid figure, and the height can be the vertical distance from the lower surrounding surface to the upper surrounding surface of the geometric solid figure, or the vertical distance from the upper surrounding surface to the ground.

[0106] When the type information of the entity is a columnar graph, the length of the entity can be the radius or the circumference of the lower surrounding surface of the column, the width of the entity can be the radius or the circumference of the lower surrounding surface of the column, and the height of the entity can be the vertical distance from the lower surrounding surface to the upper surrounding surface of the column or the vertical distance from the upper surrounding surface to the ground level.

[0107] It should be noted that when the entity belongs to an irregular image in the geometric solid graph / columnar graph, the length of the entity can be the distance between the two points farthest apart included in the lower surrounding surface.

[0108] When the type information of the entity is the first type and the position information of the entity includes two-dimensional coordinates, determining the three-dimensional model of the entity according to the position information and the type information of the entity can include:

[0109] determining the width of the entity according to the two-dimensional coordinates;

[0110] determining the height of the entity according to the width of the entity and the first type;

[0111] determining the three-dimensional model of the entity according to the width of the entity and the height of the entity.

[0112] Each entity can correspond to at least four two-dimensional coordinates, each two-dimensional coordinate can correspond to a connection point of the entity projected in the map, and the outline of the entity can be obtained by connecting the at least four two-dimensional coordinates in a clockwise direction / anticlockwise direction.

[0113] For example, entity A corresponds to four two-dimensional coordinates, which are left upper coordinate 1, left lower coordinate 2, right lower coordinate 3, and right upper coordinate 4. According to the two-dimensional coordinates, it can be determined that the width of the entity can be the distance between the left upper coordinate 1 and the left lower coordinate 2, or the distance between the right lower coordinate 3 and the right upper coordinate 4.

[0114] For another example, entity B corresponds to five two-dimensional coordinates, which are left upper coordinate 5, left lower coordinate 6, right lower coordinate 7, middle coordinate 8, and right upper coordinate 9. According to the two-dimensional coordinates, it can be determined that the width of the entity can be the maximum distance between the distance between the right lower coordinate 7 and the right upper coordinate 9 and the distance between the left upper coordinate 5 and the left lower coordinate 6.

[0115] The height of the entity can be the distance between the lower surrounding surface and the upper surrounding surface of the entity, or the distance between the upper surrounding surface and the ground level.

[0116] The embodiment can approximate the three-dimensional outline of the entity based on the width of the entity and the height of the entity, determine the peripheral surface material, color, etc. of the entity based on the width of the entity and the height of the entity, and effectively restore the three-dimensional model of the entity in the real scene.

[0117] The height of the entity is determined according to the width of the entity and the first type, including:

[0118] The preset first inference model is determined according to the first type, and the preset first inference model is used to describe a mapping relationship between the width of the first candidate entity and the height of the first candidate entity.

[0119] The height of the entity is determined according to the width of the entity based on the preset first inference model.

[0120] The database can store a plurality of inference models, such as a first inference model, a second inference model, etc., each inference model corresponding to an entity type, and can be used to determine the height of the same type of entity.

[0121] The first inference model is the inference model corresponding to the first type, and the mapping relationship between the width of the first candidate entity and the height of the first candidate entity can effectively represent the proportional relationship between the width of the first candidate entity and the height of the first candidate entity.

[0122] The height of the entity is determined according to the width of the entity based on the preset first inference model, which can include: based on the preset first inference model and the proportional relationship between the width of the first candidate entity and the height of the first candidate entity, the height of the entity is calculated.

[0123] Therefore, based on the first inference model obtained from the entity in the real scene, the real height of the entity of the first type can be accurately estimated.

[0124] When the type information of the entity is the second type, the position information of the entity includes a two-dimensional coordinate and a radius, and the two-dimensional coordinate includes a head point coordinate and a tail point coordinate, the three-dimensional model of the entity is determined according to the position information and the type information of the entity, including:

[0125] The direction vector of the entity is determined according to the head point coordinate and the tail point coordinate.

[0126] The first distance between the head point coordinate and the tail point coordinate is calculated.

[0127] The height of the entity is determined according to the first distance and the second type.

[0128] The three-dimensional model of the entity is determined according to the direction vector of the entity and the height of the entity.

[0129] The head point coordinate and the tail point coordinate can be the center point coordinates of the upper and lower surrounding surfaces of the entity, respectively. When the head point coordinate is the center point coordinate of the upper surrounding surface of the entity, the tail point coordinate can be the center point coordinate of the lower surrounding surface of the entity, or when the head point coordinate is the center point coordinate of the lower surrounding surface of the entity, the tail point coordinate can be the center point coordinate of the upper surrounding surface of the entity.

[0130] It should be noted that the head end point coordinate is the coordinate of the first point under the entity when the target data is parsed, and the tail end point coordinate is the coordinate of the second point under the entity when the target data is parsed.

[0131] The direction vector of the entity can be a vector in the direction from the head end point to the tail end point.

[0132] The height of the entity can be the distance between the lower enclosing surface of the entity (such as the enclosing surface where the head end point is located) and the upper enclosing surface (such as the enclosing surface where the tail end point is located), or the distance between the upper enclosing surface of the entity (such as the enclosing surface where the tail end point is located) and the ground plane (such as the plane where the head end point is located).

[0133] The embodiment can approximate the three-dimensional profile of the entity based on the direction vector of the entity and the height of the entity, and determine the peripheral surface material, color, etc. of the entity based on the direction vector of the entity and the height of the entity, so as to effectively restore the three-dimensional model of the entity in the real scene.

[0134] The height of the entity can be determined based on the first distance and the second type, including:

[0135] The second inference model is determined according to the second type, and the second inference model is used to describe the mapping relationship between the second distance between the head end point coordinate and the tail end point coordinate of the second candidate entity and the height of the second candidate entity.

[0136] The height of the entity is determined based on the first distance and the second inference model.

[0137] The second inference model is one of the inference models stored in the database, which can correspond to the second type, and the mapping relationship between the second distance between the head end point coordinate and the tail end point coordinate of the second candidate entity and the height of the second candidate entity can effectively represent the proportional relationship between the second distance between the head end point coordinate and the tail end point coordinate of the second candidate entity and the height of the second candidate entity.

[0138] The height of the entity is determined based on the second distance and the second inference model, which can include: based on the second inference model and the proportional relationship between the second distance and the height of the second candidate entity, the height of the entity is calculated.

[0139] Therefore, based on the second inference model obtained from the entity in the real scene, the real height of the entity of the second type can be accurately estimated.

[0140] S140, according to the position information of the entity and the three-dimensional model of the entity, a target simulation scene is constructed.

[0141] The three-dimensional model of the entity can be drawn into the target simulation scene according to the position information of the entity in the target data and the three-dimensional model corresponding to the entity, so as to construct the simulation scene with three-dimensional information.

[0142] The simulation scene construction method provided in the embodiment can obtain target data, perform data analysis on the target data to obtain position information and type information of an entity in the target data, determine a three-dimensional model of the entity according to the position information and the type information of the entity, restore the height of the entity with missing height information, expand the three-dimensional information of the entity, and effectively construct a target simulation scene according to the position information of the entity and the three-dimensional model of the entity, thereby facilitating intuitive and effective identification of a scene where the entity is located.

[0143] Figure 2 is a flowchart of another simulation scene construction method provided in the embodiment of the disclosure. The embodiment is based on the above-mentioned embodiment, and further includes the following steps before S140:

[0144] S131, constructing an initial simulation scene based on the target data.

[0145] The initial simulation scene is a two-dimensional simulation scene.

[0146] The initial simulation scene constructed based on the target data can include a two-dimensional graph corresponding to each entity in the target data. For example, the initial simulation scene can include a two-dimensional graph corresponding to a vehicle, a road line, an overpass, and the like. Figure 3 For example, as shown in the example.

[0147] Figure 3 The two-dimensional graph can include a top view state of a plurality of entities, such as a vehicle, a road line, an overpass, and the like.

[0148] One possible implementation of S140 is as follows:

[0149] S1401, inserting a three-dimensional model of an entity into the initial simulation scene based on position information of the entity, to obtain a target simulation scene.

[0150] The target simulation scene can be a three-dimensional simulation scene, which can effectively reflect three-dimensional characteristics of an entity included in the scene. For example, as shown in the example. Figure 4 For example, as shown in the example.

[0151] Figure 4 The target simulation scene can include a region 1, a region 2, and a region 3.

[0152] The region 1 can be used to describe a three-dimensional model corresponding to a vehicle, the region 2 can be used to describe a three-dimensional model corresponding to a road sign, and the region 3 can be used to describe a three-dimensional model corresponding to a portal column.

[0153] It should be noted that in the target simulation scene, different colors can be used to mark the three-dimensional models of different entities, so as to facilitate observation.

[0154] Optionally, based on the type information of the entity, the target simulation scene can be constructed in the following multiple implementation manners.

[0155] In some embodiments, when the type information of the entity is a first type, the center point coordinates of the entity are calculated according to the position information of the entity.

[0156] Based on the center point coordinates, the three-dimensional model of the entity is inserted into the initial simulation scene to obtain the target simulation scene.

[0157] In the initial simulation scene, the two-dimensional graph with the entity can be used to construct the three-dimensional model of the entity to the position of the entity in the initial simulation scene according to the center point coordinates of the entity, so as to effectively obtain the target simulation scene with the three-dimensional characteristics of multiple entities.

[0158] In some embodiments, when the type information of the entity is a second type, the center point coordinates of the entity are calculated according to the position information of the entity.

[0159] Based on the center point coordinates and the direction vector of the entity, the three-dimensional model of the entity is inserted into the initial simulation scene to obtain the target simulation scene, and the direction vector of the entity is determined according to the position information of the entity.

[0160] Based on the center point coordinates of the entity and the direction vector of the entity, the position of the three-dimensional model of the entity can be calibrated, so that the entity can be constructed into the simulation scene according to the arrangement manner of the entity in the real scene.

[0161] Therefore, the fitting degree between the target simulation scene and the real scene can be effectively improved, so that the real scene where the entity is located can be accurately restored.
