Title:
MULTIMODAL FUSION OBSTACLE DETECTION METHOD AND APPARATUS BASED ON ARTIFICIAL INTELLIGENCE BLINDNESS GUIDING
Document Type and Number:
WIPO Patent Application WO/2023/015799
Kind Code:
A1
Abstract:
Disclosed in the present invention is a multimodal fusion obstacle detection method based on artificial intelligence blindness guiding, comprising: respectively obtaining an infrared image and a color image of a scene by means of an infrared camera and a color camera; respectively sending the obtained infrared and color bimodal images to a convolutional neural network Q1 and a convolutional neural network Q2, the convolutional neural network Q1 and the convolutional neural network Q2 respectively converting the images into a first multi-channel feature map and a second multi-channel feature map for later flattening into vectors; representing the first multi-channel feature map and the second multi-channel feature map in a vectorized manner, and performing feature vector encoding on a sequence of the first multi-channel feature map and a sequence of the second multi-channel feature map to generate multiple prediction vectors; and classifying the generated multiple prediction vectors and performing position prediction on same. According to the present invention, a Transformer structure is introduced during an obstacle detection process to more effectively achieve multimodal fusion, and a Transformer-block is introduced to fully fuse the features of infrared and color images, such that the obstacle detection accuracy in a low-illumination scene is improved.
