Missing Citation

In the original publication [1], Ref. [31] was not cited. The citation has now been inserted in Related Works, Paragraph 1 and should read:

Figure 1. Diagram of the three types of collaboration strategies [31]. (a) Precoordinated vehicle feature fusion process. (b) Midphase feature fusion process of the cooperative vehicle. (c) Late feature fusion process of the cooperative vehicle.

In the original publication, Ref. [40] was not cited. The citation has now been inserted in HP3D-V2V Algorithm, Point Cloud Denoising, Paragraph 1 and should read:

Given the complexity of the environment in vehicle perception tasks, LiDAR point cloud data (PCD) usually has a large amount of nonvehicle noise, such as ground noise, wall point noise, and sensor noise [40].

The order of other references in the original manuscript has been adjusted accordingly. The newly added references appear below:
