AI Technical Summary
In existing technologies, road topology construction methods are costly and inflexible in parking lot scenarios, making them unsuitable for most parking lots without high-precision maps and unable to handle scenarios with no lane lines or partially missing lane lines.
By dividing the historical vehicle trajectory in the vehicle mapping data into several segments, it is detected whether there is a complete lane line in each segment. If not, a first centerline topology is generated, and multiple segments of the first centerline topology are connected to construct the final centerline topology. Vehicle data is obtained using sensors such as binocular cameras and fisheye cameras to generate semantic data of parking lots, and road topology is generated by combining heuristic generation algorithms such as the Veno map algorithm.
It enables the construction of stable and smooth road topology maps in parking lot scenarios with no lane lines or incomplete lane lines, and is suitable for various parking scenarios.
