Abstract: According to the present invention, firstly multiple reference parameter values of each color sample in a color chart are set, or a photograph and a measurement are performed on a standard color chart or a user-defined color chart in a certain standard lighting environment, multiple reference parameter values, SPD (?)×R (?) and brightness of each color sample are obtained. Then the SPD (?)×R (?) and the brightness of each color sample are reproduced by using a spectral tunable lighting source. Then each reproduced color sample is photographed by using the camera under the same settings to obtain multiple reproduced parameter values of each color sample. The two groups of parameter values are compared and a color calibration model is established. Finally color calibration of each batch of camera modules is implemented without the helping of a color chart and standard lighting environment.

Geometric calibration of the camera units with respect to the imaged scene is performed by detecting features within captured images, generating descriptors from respective patches of the image at the features; detecting corresponding descriptors from different images, and deriving the geometric calibration from the positions in the respective images of the corresponding descriptors. A target location in the image captured by a first optical sighting apparatus is designated and a corresponding location relative to the image captured by the second one optical sighting apparatus is identified from the geometric calibration. The display device of the second optical sighting apparatus indicates where the corresponding location lies relative to the displayed image.
