Problems solved by technology
The preliminary identification of road markers can be accomplished by combining geometric feature extraction and pattern matching. However, since this method is not accurate, in order to ensure the accuracy of the data, it is necessary to provide a data display scheme to Used for post-editing and testing of data
[0003] Using the data display scheme provided by the existing technology, one scheme is: in order to improve the accuracy of the data, the color information corresponding to the road sign data is attached to the initial point cloud data. Therefore, the amount of data that needs to be processed is greatly increased. increase, the time cost and labor cost are huge, and the processing efficiency is low; another solution is: it is necessary to switch the processing window between 2D and 3D scenes frequently, and it does not use data editing, and the processing efficiency is also low; another solution Yes: During the two-dimensional to three-dimensional mapping process, due to the influence of noise interference and low sampling accuracy, the recognition accuracy of road sign data is reduced, and the expected processing efficiency cannot be achieved.
However, in related technologies, there is no effective solution to this problem

The present invention discloses a display method and terminal for marking data, wherein the method includes: collecting first data, the first data is used to identify the position of at least one sampling point in the collected area in three-dimensional space; according to The first data establishes a three-dimensional virtual space; the second data is obtained, and the second data is used to characterize the media information obtained by presenting the target object in a two-dimensional space in the collected area; according to the extracted projection strategy, the obtained The second data is directly projected into the three-dimensional virtual space for display, and a display result including the third data is obtained; according to the third data, the target object is marked with a corresponding color to distinguish its mark attribute information.
Description
technical field [0001] The present invention relates to data display technology, in particular to a display method and terminal of mark data. Background technique [0002] Road markers such as traffic lights and speed limit signs can assist traffic travel. Combining road markers with geographical location information of traffic travel can provide users with more comprehensive data display results for traffic travel. The preliminary identification of road markers can be accomplished by combining geometric feature extraction and pattern matching. However, since this method is not accurate, in order to ensure the accuracy of the data, it is necessary to provide a data display scheme to It is used for post-editing and testing of data. [0003] Using the data display scheme provided by the existing technology, one scheme is: in order to improve the accuracy of the data, the color information corresponding to the road sign data is attached to the initial point cloud data. Therefo...
