How to use Lightroom camera calibration 1, Lightroom camera calibration using the method is very simple, first we open the Lightroom software, in the gallery to select the photos you want to process. Lightroom 2, in the Lightroom choose to modify the photo option, click on the right side of the camera calibration. Lightroom 3, in the Lightroom camera calibration We can adjust the shades of shade. 4. We use the Lightroom camera to

meet the assumption of the camera, so there exists r| between the projection equipment and the space point (x,y,z). The outer parameter of T. Given the projection device and the internal parameter matrix of the camera, moreover, the external parameters are calculated in advance by a general calibration algorithm, then the value of z can be computed by the mapping Point (XG,YG) of the space point on the projection device and the mapping Point (Xi,yi) on the camera image plane, which is visible i

true North angle, which is the geographical angle. We notice that its type is double, that is, the Nullable 3, headingaccuracy attribute: The accuracy of the compass reading, if the reading accuracy is higher, it returns high. Our application can check whether this property is high at the right time, and if not, consider prompting the user to calibrate the compass. Referring to the calibration, it is necessary to say that the calibration compass is

after the power outage, a rechargeable battery is applied to the array card buffer unit. Today, most of the array card cache units add a rechargeable battery pack, which provides power support for the cache after a power outage, while ensuring that the data is not lost for a certain amount of time (typically 48 hours). Until the next time the server recovers power again, the array card controller will flush the data in the cache to disk to avoid dirty data generation.How the cache is powered1.
