Embodiment 1
[0051] A method for constructing a multi-plane coded point cloud feature deep learning model based on pointpillars, comprising the following steps:
[0052] Step 1: Obtain a training sample, the training sample includes point cloud data containing the detection target and label information corresponding to the point cloud data, the label information is used to indicate the bounding box coordinates of the detection target in the point cloud data and the detection in the bounding box coordinates Classification label for the target.
[0053] Step 2: Use training samples to train the multi-plane encoding point cloud feature deep learning model, so that the recognition result obtained by inputting the point cloud data in the training sample into the trained multi-plane encoding point cloud feature deep learning model is the point cloud data. The location bounding box coordinates of the detection target and the existence probability of the target in the bounding box coordinates.
