Assignee: DALIAN UNIVERSITY OF TECHNOLOGY
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 2:
3. The disparity image fusion method for multiband stereo cameras according to claim 1, wherein the calculation method of the confidence specifically comprises:
(b-1) searching the cost vector corresponding to each pixel in the energy propagation diagram to obtain the minimum cost Costmin corresponding to each pixel, corresponding disparity dmin, second minimum cost CostSecMin and corresponding disparity dSecMin;
(b-2) calculating the absolute value of a difference between two disparities:

abs 2dis=|dmin−dSecMin|  (6)

(b-3) calculating a ratio between two energy values:

Rate2Energy=Costmin/CostSecMin  (7)

(b-4) in judging a size relationship between abs2dis and Rate2Energy: when abs2dis=thresh1, if Rate2Energy<thresh2, the confidence is set as 1, otherwise as 0; when abs2dis>thresh1, if Rate2Energy<thresh13, the confidence is set as 1, otherwise as 0; wherein thresh1, thresh2and thresh3 are obtained by statistics and stored in hardware in advance.
