The vision sensor is fixed on the end - effector of the robot. when the robot makes a linear movement along the " v " measurement track, the linear light from the laser electropult on the sensor is projected on the track to shape laser strip with three turning dots and imaged in ccd camera. the relation between the sensor coordinate and the measurement track coordinate can be computed by image processing and pose measuring, which indirectly describes the characteristic of the robot ' s linear trajectory
該系統利用結構光幾何成像原理和視覺圖像處理技術，將視覺傳感器固定在機器人末端，當機器人沿「 v 」形測量軌道做直線運動時，傳感器上的激光發射裝置發出的線狀光源投射在測量軌道上，形成具有三個拐點的激光條，並在ccd攝像機中成像，通過圖像處理技術和位姿測量技術，得到傳感器坐標系相對于測量軌道坐標系的位姿關系，從而間接描述機器人的直線軌跡特性。With the development of science and technology, more and more oxide crystals are synthesized by more and more advanced technique, the new oxide crystals are incessantly synthesized and the new characters of oxide crystals are incessantly founded. corundum dopped with impurity not only is cherished because of it ' s beautiful appearance, but also is used in the fields such as electrotechnics, mechanism, laser, the optic apparatus and the underlay of semiconductor. sapphire dopped with ti3 + is the best material of the tunable solid laser. zno crystal is material of the direct gap semiconductor ( the width of forbidden band : 3. 37ev ). the excited emission in zno crystal at room temperature has been found, so the ultraviolet luminescence in zno semiconductor can be acquired at room temperature
含有少量雜質的剛玉晶體（ - al _ 2o _ 3 ）不僅由於其色澤艷麗成為人們珍愛的名貴寶石，而且由於它具有的優異性能，被廣泛應用於電工、機械、激光器，光學器件和半導體襯底材料。鈦藍寶石是目前最優異的固體寬帶調諧激光材料，用於製作飛秒脈沖可調諧激光器。氧化鋅晶體是直接帶隙寬禁帶半導體材料（禁帶寬度3 . 37ev ） ，現已發現具有室溫下受激發射特性，有可能實現室溫下半導體紫外發光。Departure for famous universal studio. over here, you will be in major movie shot locations and experience the special affections of star war, earthquake, volcano, ten commandment. just to name some. you can also biking along with e. t
