Problems solved by technology

[0004] However, the existing post-fusion multi-sensor detection scheme requires rules and probabilities as the basis for data association. On the one hand, the process is longer and causes higher delay; on the other hand, data-driven optimization of the entire fusion system cannot be used.

Abstract

The embodiment of the invention discloses an object detection method, a device, a storage medium and a vehicle. The method comprises the following steps: inputting scene point cloud data into a pre-trained point cloud feature extraction model to obtain scene point cloud description features; inputting scene image data into a pre-trained image feature extraction model to obtain scene image description features; The point cloud descriptive features and image descriptive features of each target region in the scene are input into a pre-trained object recognition model, and the detection results ofthe objects located at each target region are obtained. Compared with the existing post-fusion multi-sensor detection scheme, the technical scheme of the invention corresponds to the pre-fusion multi-sensor detection scheme of features, does not need to use rules and probabilities as the basis of fusion to carry out data association, and simplifies the detection process while detecting an object.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of sensors, and in particular to an object detection method, device, equipment, storage medium and vehicle. Background technique [0002] With the development of sensor technology, multiple sensors are used to detect the same object or environment at the same time, and the detection results obtained by fusing the detection data of multiple sensors are compared with the detection of the same object or environment by a single sensor. The results are more comprehensive and accurate. Therefore, multi-sensor fusion detection is mostly used in the fields of object detection or target tracking. [0003] At present, the post-fusion multi-sensor detection scheme is mainly used in the multi-sensor fusion detection scheme. A typical post-fusion processing process is as follows: figure 1 The result shown is equivalent to the fusion of results. Sensors 1 and 2 respectively transmit the sensin...
