Abstract: The present invention provides a hardware-aware mixed-precision quantization method and system based on a greedy search. It comprises quantizing all layers in the neural network to the uniform bit-width, conducting training-aware quantization, and acquiring the trained model, baseline inference accuracy, and total bit operation counts. Each layer in the neural network undergoes post-training quantization with low precision individually, and the corresponding inference accuracy and total bit operation counts for each layer are recorded. Single-layer sensitivity is computed based on the baseline inference accuracy, total bit operation counts, and the inference accuracy and total bit operation counts of each layer and guides the current total bit operation counts until reaching the preset maximum bit operation counts. Meanwhile, quantized layers and precision are recorded, determining the mixed-precision quantization strategy. This invention introduces single-layer sensitivity, wi early in the search, thereby achieving an optimized quantization strategy that balances hardware costs and inference accuracy.

Abstract: A pose graph synchronous localization and mapping computation method based on a 4D millimeter-wave radar includes comparing two consecutive frames of point clouds in a 4D radar point cloud to remove ghost points below a ground surface and random points, estimating a linear velocity and an angular velocity of a device based on Doppler velocity information in the 4D radar point cloud, and estimating and constructing a pose graph using a relative pose transformation, and estimating an optimal pose for the pose graph through graph optimization. To achieve better accuracy for a sparse point cloud, estimated ego vehicle velocity is pre-integrated to obtain an additional relative pose estimate, and loop closure detection is used to identify places already reached.

Abstract: A three-dimensional point cloud upsampling method includes: dividing a three-dimensional point cloud into overlappable point cloud blocks which have a fixed number of points and are capable of covering all the points; extracting hierarchical features according to point coordinates in the point cloud blocks; achieving point set feature expansion of the extracted hierarchical features by using multi-scale heat kernel graph convolution; and reconstructing point coordinates in an upsampled three-dimensional point cloud from the expanded features. According to the present disclosure, detail information enhancement with different fine granularities can be performed on the three-dimensional point cloud which is sparse and nonuniformly distributed in the space, and at the same time, good stability is provided for overcoming potential noise disturbance and local deformation. The method can promote the uniformity of spatial distribution of the upsampled dense point cloud, and ensure the accurate representation for a geometric structure of a target object.
