Problems solved by technology
[0002] At present, large-scale high-precision maps are prone to problems such as irregularities in the production process, negligence, or failure to make some roads, resulting in interruptions in the connectivity of some routes, which in turn leads to the failure of route planning.
The existing road connectivity test method for high-precision maps uses manual testing, which requires manual setting of the starting point and end point, and setting the area to be tested as a single path to test road connectivity, which has high labor costs and low efficiency

The embodiment of the invention provides a road connectivity test method and system based on a large-range high-precision map, and the method comprises the steps: obtaining the form point informationof all lane lines in high-precision map data, and extracting two form point sample sets with the same number of samples from the form point information; respectively taking shape point samples in thetwo groups of shape point sample sets as a starting point and an ending point to obtain a test sample set; and finally, performing path planning according to each test sample in the test sample set toobtain a test sample with path planning failure, thereby obtaining a path with disconnected roads. According to the method, a large number of test samples for road connectivity testing can be rapidlyobtained, path planning is executed based on the large number of test samples, paths which are not planned can be rapidly found, compared with the prior art, the manual testing cost is reduced, the problem positions of road disconnection can be efficiently found, and the road connectivity test efficiency of a large-range high-precision map is improved.
Description
technical field [0001] The invention relates to the field of high-precision map testing, in particular to a road connectivity testing method and system based on a large-scale high-precision map. Background technique [0002] At present, large-scale high-precision maps are prone to problems such as irregularities in the production process, negligence, or non-production of some roads, resulting in interruptions in the connectivity of some routes, which in turn lead to the failure of route planning. The existing road connectivity test method for high-precision maps uses manual testing, which requires manual setting of the starting point and end point and setting the area to be tested as a single path to test road connectivity, which has high labor costs and low efficiency. [0003] Therefore, how to provide a set of testing methods for road connectivity of large-scale high-precision maps to find out which routes have normal connectivity and which routes cannot be used for path ...
