A detailed description of the polar angleNoun Interpretation:In the plane to take a fixed point o, called the Pole, a ray of ox, called the polar axis, and then select a length unit and angle of the square direction (usually counterclockwise). For any bit of m in the plane, the length of the segment OM is represented by the ρ (sometimes denoted by R), θ denotes the angle from ox to OM, ρ is called the polar
with more things in the computer world, how are you adjust these depends on the what you ' re trying to do. In many cases we has fast disk subsystems with their own big, battery-backed NVRAM caches, so keeping things in the OS PA GE Cache is risky. Let's try to send I/O to the array in a further timely fashion and reduce the chance our local OS would, to borrow a phrase fr Om the service industry, being "in the weeds." To does this we lower vm.dirty_

start the run stereo Calibration, the result after run is as follows, the parameters of the left and right camera are corrected, and the rotation and migration relationship vectors between the two cameras (OM and t) are also calculated.By clicking on the show Extrinsics of Stereo rig on the panel, you can see the dual camera diagram shown in the figure below, and you can see that two cameras are basically forward parallel!

. Theoretically there are norflash and DDR2, but Samsung also added another SRAM. Why do you want to add SRAM? Because Norflash can only read, cannot write, then cannot carry on the data exchange, but DDR2 at this time also cannot use, then only then uses the SRAM to save the global data and the setting stack space. So 210 of the storage structure is irom (similar to norflash) +SRAM+DDR2 structure. Here, as an example of an SD card boot, the system detects the level of the
method of automatic word segmentation, it needs to spend more time scanning the segmentation flag, increase storage space to store those non-natural segmentation signs.Best Fit Method (OM). This method is divided into the positive best matching method and the inverse best matching method, the starting point is: in the dictionary according to the size of the word frequency order the entry, in order to shorten the retrieval time of the thesaurus, to ac
