The invention relates to an intelligent vehicle unsealing method. The intelligent vehicle unsealing method comprises the following step of using an intelligent vehicle unsealing system to realize intelligent unsealing operation on a rear cover of a gas storage tank of a gas storage vehicle, wherein the intelligent vehicle unsealing system comprises a composite type imaging device and a data extracting device; the composite type imaging device comprises a light filter, a camera lens, a camera lens support, multiple lenses and multiple CMOS (Complementary Metal-Oxide Semiconductor) sensors and is used for carrying out imaging processing on personnel coming to unseal, the multiple lenses and the multiple CMOS sensors are the same in quantity, and each CMOS sensor corresponds to one lens and is used for carrying out photovoltaic conversion on transmission light from the corresponding lens so as to obtain a high-definition transmission image; the data extracting device is connected with the composite type imaging device and is used for receiving multiple high-definition transmission images output by the multiple CMOS sensors, determining the central point and the DOF (Depth of Field) of each high-definition transmission image and averaging the DOF of all high-definition transmission images so as to obtain the DOF of a site.
