We once had to remove a controversial book from a bookshelf in the background in one project and it came in very handy. Mocha’s primary uses include brand replacement, item removal and logo replacement. Not spending much time creating visual effects I was surprised how useful a tool like Mocha was to a full-time editor for situations like he billboard, and a great deal of other things, too. Mocha Pro, like the original Mocha, uses planar tracking to track regions of planar surfaces in your footage, not just a few local pixels, computing not only second variables, such as X-Y movement, rotation and scale, but 3D elements such as perspective, for ultra-convincing replacement of any part of your scene. It combines the functionality of previously available products into one single package, making it easier to get the job done faster.
The field test shows that the acceleration of the rail, clip, iron pad, and track bed in the MTHDRP laying section is significantly lower than that in the PTRP laying section, and the rail surface roughness improves significantly after the rail pad is replaced with the MTHDRP for half a year.Mocha Pro is the latest version of the company’s planar tracking software. The dynamics model calculation has discovered that the increase of the rail pad damping coefficient can not only effectively decrease the vibration acceleration, wheel–rail force, and derailment coefficient, but also is beneficial for both vehicle safety and stability and track structure protection. It is concluded that the MTHDRP has the highest damping coefficient than any other rail pads. The mesh–type high damping rail pad (MTHDRP) is proposed for the first time in this paper, and the differences in damping performance between MTHDRP and traditional rail pads (PTRP and GRP) are compared and studied. The rail pad damping is a critical parameter to evaluate its vibration reduction capacity, which has essential research significance.
