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 but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but could have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, subprograms, and the like.
Example one
Fig. 1 is a flowchart of an information visualization method according to an embodiment of the present invention, where the present embodiment is applicable to information visualization in an automatic driving high-precision positioning test, and the method may be executed by an information visualization apparatus provided in an embodiment of the present invention, where the apparatus may be implemented by software and/or hardware, and the apparatus may be configured on an electronic computing device, for example, a vehicle-mounted terminal. The method specifically comprises the following steps:
and S110, acquiring vehicle positioning information and a map file.
The vehicle positioning information may be real-time position information of the vehicle during the driving process of the autonomous vehicle, and the vehicle positioning information includes, but is not limited to, latitude, longitude, x-direction speed of a vehicle coordinate system, y-direction speed of the vehicle coordinate system, z-direction speed of the vehicle coordinate system, x-direction acceleration of the vehicle coordinate system, y-direction acceleration of the vehicle coordinate system, z-direction acceleration of the vehicle coordinate system, heading angle, pitch angle, roll angle, x-direction coordinate of a UTM coordinate system, y-direction coordinate of the UTM coordinate system, z-direction coordinate of the UTM coordinate system, latitude standard deviation, longitude standard deviation, roll angle standard deviation, pitch angle standard deviation, heading angle standard deviation, GNSS time, difference state, GNSS stability state, sending timestamp, and the like.
The map file may be a map file containing the test area. Alternatively, the map file may be a high-precision map file in XML format. The high-precision map file in the XML format contains various road marking information, and convenience is brought to map integration and interaction. The road marking information may be object information related to roads in the high-precision map file, and the road marking information includes, but is not limited to, information such as points, lane lines, roads, and road-circumscribed polygons. The map file may be acquired from a preset storage location, where the preset storage location may be a storage medium located in the vehicle-mounted terminal, or may be a storage medium located in a remote server, and this embodiment does not limit this.
Specifically, the vehicle positioning information may be acquired by a GPS/IMU integrated navigation system positioning method, a matching positioning method, or a multi-sensor fusion positioning method. The GPS positioning mainly depends on satellites to confirm the position of the vehicle, has the characteristics of all weather, small accumulated error and the like, but can generate serious position deviation in a sheltering environment, and meanwhile, the output frequency of the GPS positioning is difficult to meet the requirements of an automatic driving system. The odometer positioning is the dead reckoning of an automatic driving vehicle by means of a gyroscope, an accelerometer and the like, the output frequency is high, the dead reckoning is not influenced by environment shielding, but the positioning error is increased along with the lapse of time, and the GPS/IMU integrated navigation system positioning method combines the GPS positioning and the odometer positioning, has the common advantages of the GPS positioning and the odometer positioning and simultaneously reduces the influence of shielding and error accumulation on the positioning precision of the vehicle. The matching positioning method is characterized in that a sensor is used for scanning surrounding environment to construct an offline environment map, and then the environment information detected in real time by the sensor is matched with the offline environment map to obtain the relative position of the automatic driving vehicle in the offline map, so that the positioning result is corrected, and the influence of shielding and error accumulation is effectively reduced. The multi-sensor fusion positioning method can be used for fusing vehicle positioning information obtained by a GPS/IMU integrated navigation system positioning method and a matching positioning method through a Kalman filtering algorithm to obtain vehicle positioning information with higher robustness and more reliability.

The lane line and the road external polygon can be formed by a plurality of points, the road comprises a road type and a lane, and the intersection comprises an intersection central point, a road external polygon, a connection mode and an intersection type.
Specifically, the method for analyzing the information of the map file comprises the following steps: in some embodiments, the map file may be parsed through a hierarchical object model to extract map feature information in the map file. The hierarchical object model divides the map file into independent elements, attributes, annotations and the like, then represents the map file in a node tree form, then classifies the node tree according to the attributes, the annotations and the like, and divides the map feature information of the same category into the same branch, so as to realize the classification and extraction of the map feature information in the map file. In some embodiments, the map file may be scanned based on a sequential pattern, an event processing function is notified when the beginning and the end of the file, the beginning and the end of the element, the end of the file, and the like are scanned, a corresponding parsing action is performed by the event processing function, and then the same scanning is continued until the end of the file, and the parsing of the map file and the extraction of the map feature information are completed.
S130, performing visual window drawing based on the vehicle positioning information and the map characteristic information to obtain a visual display picture, wherein the visual display picture comprises a test map and a vehicle identifier, and the visual display picture is used for displaying the position of the vehicle identifier in the test map.
The visualization window can be used for displaying a visualization display picture corresponding to the vehicle positioning information and the map feature information.
