Embodiment Construction

[0080] At present, data fusion methods for image acquisition equipment and point cloud acquisition equipment can be divided into pre-fusion methods and post-fusion methods.

[0081] Among them, the pre-fusion method is a method of processing at the original data level, which may specifically include: projecting the original point cloud data of the point cloud collection device onto the original image data, converting the pixel information of the image data from pure color information (such as red Green and blue information, etc.) are amplified into fusion information of color and depth for data analysis.

[0082] The post-fusion method is a method of processing at the level of data results, which may specifically include: independent data processing of the original image data collected by the image acquisition device and the original point cloud data collected by the point cloud collection device to obtain the target perception result, combined with The target perception resul...

Abstract

The invention discloses a data processing method, a data processing device and an automatic driving system, and the data processing method comprises the steps: carrying out the feature extraction of original point cloud data, and obtaining first point cloud feature data; performing feature extraction on the original image data to obtain first image feature data; based on preset target classification candidate information, screening the first point cloud feature data and the first image feature data to obtain second point cloud feature data and second image feature data; fusing the second point cloud feature data with the second image feature data to obtain fused data; and performing target identification on the fused data to obtain a target identification result. By adopting the above scheme, the processing efficiency and accuracy of data fusion can be guaranteed with low implementation cost, and thus a more accurate target recognition result can be obtained.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a data processing method, data processing equipment, and an automatic driving system. Background technique [0002] At present, autonomous driving systems are often equipped with sensor suites composed of different sensors, such as point cloud acquisition equipment, image acquisition equipment, integrated navigation equipment and other sensors. The automatic driving system relies on the sensor's perception of the environment. The more accurate the environmental information obtained by the sensor, the more timely and accurate the automatic driving system can make driving decisions and realize automatic driving. [0003] However, in the existing sensors for automatic driving systems, the environmental information perceived by a single sensor is limited, and cannot meet the complex and changeable requirements in real driving scenarios. For example, although the image acquisition de...
