The rest paper consists of three parts. Section 2 constructs the geometrical model of the active solution of the homography. The laser points of the laser lines are derived from the projections on the 2D reference in different positions. Then, the 3D laser lines are initialized and optimized by the 3D laser points in the camera coordinate system. Finally, the laser lines are projected to the pavement. The homography is determined by the laser projections on the pavement and the related image points. Section 3 performs the experiments to recover the pavement cracks with the active solution of homography. The recovery accuracy is also estimated in the experiments. Section 4 provides the conclusion.

In order to evaluate the accuracy of the active solution method, the recovery errors of the homography are verified by experiments. The 225 corners of the checkerboard pattern on the target board are extracted as the feature points. The homography matrix is solved by the proposed method. The image coordinates of the 225 feature points are transformed to the real-dimension pavement coordinates by the homography. The recovery accuracy is evaluated by the differences between the reconstructed real-dimension coordinates and the real coordinates of feature points on the target. Two impact factors are considered in the experiments. One factor is the measurement distance between the target and the camera. The other factor is the relative angle between the optical axis of the camera and the normal vector of the target. In addition, the initialization method and the optimization method of the laser
Since you wear each tray for two weeks, the timing of the crack is important and will determine what your dentist suggests. If you are in the early days of wearing a set of trays, he or she may tell you to go back to the previous set of trays. In the meantime, they will order you a replacement for the broken one.
If you crack your Invisalign tray, it does not need to cause you stress. There is an easy solution depending on the extent of the damage and its timing. If you notice a crack or a break in your Invisalign device, contact your dentist for the option that is best for you and your teeth.
Side-channel attacks involve collecting information about what a computing device does when it is performing cryptographic operations and using that information to reverse-engineer the device's cryptography system. These attacks may use timing information, such as how long it takes the computer to perform computations; electromagnetic leaks; audio clues; and optical information -- for example, from a high-resolution camera -- to discover extra information about how the system is processing the AES encryption. In one case, a side-channel attack was used successfully to deduce AES-128 encryption keys by carefully monitoring the cipher's shared use of the processors' cache tables.

If you own a diesel-powered vehicle, in addition to the reasons discussed above, white smoke from exhaust is usually caused by low cylinder compression, low fuel pressure to the fuel pump, damaged fuel lines, incorrect or broken fuel pump timing, broken injection timing, cracked or damaged rings or cylinder liners, and broken crankshaft keyway. 2ff7e9595c
