Embodiment Construction
[0091] Embodiments of the present invention will be described in detail below, and examples of the embodiments are illustrated in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. The following is exemplary, and is intended to be illustrative of the invention, not to be construed as limiting the invention.
[0092] The present invention proposes a method of analyzing a road point cloud error scenario based on spatial plane offset analysis model, such as Figure 1 ~ 2 Indicated.
[0093] Step 1, the external road point cloud data acquisition, the local plane feature on the selected road is the reference plane S 0 .
[0094] Step 1.1, reference flat feature selected: For the reference plane S in step 1 0 The selection, the structure of the road and its supporting facilities, select a flat pavement, zebra crossing, road sign, road side identification card, etc. in the direction of trav...
