Abstract: A disparity image fusion method for multiband stereo cameras belongs to the field of image processing and computer vision. The method obtains pixel disparity confidence information by using the intermediate output of binocular disparity estimation. The confidence information can be used to judge the disparity credibility of the position and assist disparity fusion. The confidence acquisition process makes full use of the intermediate output of calculation, and can be conveniently embedded into the traditional disparity estimation process, with high calculation efficiency and simple and easy operation. In the disparity image fusion method for multiband stereo cameras proposed by the method, the disparity diagrams participating in the fusion are obtained according to the binocular images of the corresponding bands, which makes full use of the information of each band and simultaneously avoiding introducing uncertainty and errors.

Abstract: A service request is received by a terminal device. First biometric authentication information of a user associated with the service request is collected. The first biometric authentication information is compated with preset biometric authentication information. When the comparison shows that the first biometric authentication information and the preset biometric authentication information are consistent, a pre-stored digital signature certificate private key is read. The service request is digitally signed according to the digital signature certificate private key. A biometric information verification message is generated and sent message to a server. The server is configured to read a pre-stored digital signature certificate public key corresponding to the digital signature certificate private key. Authentication result information is receiving from the server after the server verifies and signs the biometric information verification message according to the digital signature certificate public key.
