Embodiment 1

[0025] According to Embodiment 1 of the present invention, a method for evaluating the accuracy and recall of lane line data is provided, such as figure 1 As shown, it is a schematic flow chart of the method for evaluating the accuracy and recall of lane marking data provided by Embodiment 1 of the present invention. The method at least includes the following steps:

[0026] S101, selecting a trajectory segment including at least one preset typical feature, and marking the selected current trajectory segment;

[0027] S102, for the marked current trajectory segment, automatically extract the first lane line data according to the automatic identification and extraction method of the target data;

[0028] S103, for the marked current track segment, according to the way of manually making the expected target data, make the second lane line data of the expected target including at least the expected line type and the expected attribute, wherein the second lane line data also incl...

Embodiment 2

[0046] According to Embodiment 2 of the present invention, a specific application example of a method for evaluating the accuracy rate and recall rate of lane marking data is provided.

[0047] The method for evaluating the correct rate and recall rate of lane line data provided by Embodiment 2 of the present invention is used in the data processing process of intelligently generating high-stationary maps. Positioning system), IMU (Inertial measurement unit, inertial measurement unit) and other methods to automatically extract the lane line data to verify, and to perform effective automatic evaluation on the accuracy and recall rate of the extracted lane line data.

[0048] It should be noted that the IMU inertial measurement unit is a device that measures the three-axis attitude angle (or angular rate) and acceleration of an object. Gyroscopes and accelerometers are the main components of the IMU, and their accuracy directly affects the accuracy of the inertial system. In ac...

Abstract

The present invention discloses a method and a system for evaluating the correct rate and recall rate of lane line data, wherein the method includes: for the marked current trajectory segment, automatically extracting the first One lane line data; for the marked current track segment, make the second lane line data of the expected target; according to the preset first rule, automatically extract the first lane line data and the second lane line data of the expected target Matching, to obtain the corresponding matching result; to obtain the corresponding matching result, after the corresponding matching result shows: after the automatically extracted first lane line data matches the second lane line data of the expected target, according to the second preset rule , evaluate the accuracy rate and recall rate of the automatically extracted first lane line data, and obtain the corresponding evaluation results. The solution of the present invention has the advantages of faster speed, complete automation, and more comprehensive inspection and evaluation types.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for evaluating the accuracy rate and recall rate of lane line data. Background technique [0002] In the existing technologies, there are often the following methods for evaluating the extracted lane line data: [0003] An evaluation method that checks the specifications of the automatically extracted lane line data, and obtains the corresponding evaluation results for each specification by sequentially checking the preset specifications. [0004] Another evaluation method uses a manual method to evaluate the correctness and recall rate of the lines corresponding to the automatically extracted lane line data. View the trajectory frame by frame, and finally evaluate the correctness and recall rate of the automatically extracted lane line data based on the frame-by-frame viewing results. The above process will be time-consuming and labor-intensive. The...
