[0036] Example one
[0037] figure 1 A flowchart of a method for forecasting the behavior of a vehicle according to a first embodiment of the invention, applicable to embodiments of the unmanned vehicle behavior prediction technology of the present embodiment. The method may vehicle behavior provided by the embodiment of the present invention performs prediction means, which means may be software and / or hardware implemented in the manner employed, and can be integrated on the electronic device.
[0038] Specifically, such as figure 1 , The vehicle behavior prediction method according to an embodiment of the present invention, may comprise the steps of:
[0039] S110, obtaining the three-dimensional point cloud data acquired in-vehicle sensors.
[0040] Wherein the three-dimensional point cloud data acquired by the laser sensors radar-based vehicle. Three-dimensional point cloud data is not RGB image data, comprising in addition to the collection position, but also contains a we...

[0058] Example 2
[0059] figure 2 A flowchart of a vehicle behavior prediction method according to a second embodiment of the present invention, the method further optimized based on the above-described embodiments, specific circumstances of how to extract the spatial dimension feature presentation.
[0060] Specifically, such as figure 2 As shown, the method includes:
[0061] S210, obtaining the three-dimensional point cloud data acquired in-vehicle sensors.
[0062] Wherein the three-dimensional point cloud data acquired by the laser sensors radar-based vehicle. Three-dimensional point cloud data is not RGB image data, comprising in addition to the collection position, but also contains a wealth of information, such as color information and intensity information.
[0063] In order to speed up calculations can be simplified processing of input data. After acquiring the three-dimensional point cloud data acquired in-vehicle sensor, based on three-dimensional voxel mesh, three-d...

[0076] Example three
[0077] image 3 It is a network configuration diagram of the vehicle behavior model according to a third embodiment of the present application forecast. Embodiments of the present application on the basis of the above technical solutions of the embodiments, there is provided a preferred embodiment.
[0078] Implemented on the basis of the present embodiment, the laser radar sensor on the main vehicle, and thus the conventional target detection algorithms, the input data is 3D point cloud data is not RGB image data. In the present embodiment, the input data is a simplified process, specific process can be divided into two parts: 1) a three-dimensional voxel grid based on the three-dimensional point cloud data quantizing said quantized to obtain point cloud data; 2) by two coding the quantized data values of point cloud data, i.e. if the grid in the original input data memory, it is set to 1, and 0 otherwise. Since the input data is a simplified process to o...
