眼基距 的英文怎麼說
中文拼音 [yǎnjījù]
眼基距
英文
eye base-
In the application of mini - micro - robot visual perception, there is a need for fish - eye lenses for capturing wide field of view for navigation. though fish - eye lenses provide a wide field of view ( 180 ), they introduce significant distortion in images and the acquired images are quite warped, which makes conventional camera calibration algorithms no longer work well. this paper presents an accurate calibration framework for fish - eye lens ( a high distortion lens ) camera stereo vision system. the accurate calibration model is formulated with radial distortion, decentering distortion and thin prism distortion based on the fisheye deformation model. using fish - eye and non - linear camera model, the author employs levenberg - marquardt method to realize precise non - linear calibration for wide - view - scene dense depth image recovery
魚眼鏡頭成像立體視覺系統在微小型機器人視覺導航和近距離大視場物體識別與定位中有著廣泛的應用.盡管魚眼鏡頭攝像機具有很大的視場角（接近180 ） ，但同時也引入嚴重的圖像變形，常規的攝像機標定方法無法使用.該文提出一種標定魚眼鏡頭攝像機立體視覺系統的方法.在魚眼鏡頭變形模型的基礎上，通過考慮魚眼鏡頭成像的徑向變形、偏心變形和薄棱鏡變形，建立了魚眼鏡頭成像的精確成像模型，然後，利用非線性迭代演算法，精確求解攝像機外部參數、內部參數.實驗表明，使用該方法得到的立體視覺系統參數滿足精確恢復大場景稠密深度圖的要求Beside him was his comrade nesvitsky, a tall staff - officer, excessively stout, with a good - natured, smiling, handsome face, and moist eyes. nesvitsky could hardly suppress his mirth, which was excited by a swarthy officer of hussars walking near him. this officer, without a smile or a change in the expression of his fixed eyes, was staring with a serious face at the commanding officers back, and mimicking every movement he made

( 2 ) chinese export structure has been in a important adjusting moment in which the direction of chinese export trade development is to preserve the current dimension of non - professional labor - dense products as well as put the main point of further extension on capital - dense, technology - dense and knowledge - dense products. ( 3 ) to realize the upgrade of export structure in china, we must emphasize on orientation of competitive advantage, and convert potential comparative advantage into practical competitive one
通過分析和研究得出的基本結論是： （ 1 ）中國已發展成為世界貿易大國，但是還算不上世界貿易強國，與世界貿易強國相比，尚有很大差距，要成為世界貿易強國，還有很長的路要走； （ 2 ）中國出口商品結構已進入到一個大調整階段，今後中國商品出口貿易的發展方向應該是在保持非熟練勞動密集型產品出口已有規模的同時，將商品出口貿易進一步擴張的著眼點置於資本、技術與知識密集型產品上； （ 3 ）要實現中國出口商品結構的升級，必須以競爭優勢為導向，將潛在的比較優勢轉化為現實的競爭優勢。The paper researches the relations between blasting effect and blasting parameters, including diameter of drill, non - coincidence coefficient, hole spacing, hole row - spacing, cartridge diameter, charge per hole, density of line charge, charging structure and detonating manner, and how to adjust the blasting parameters to get the best blasting effect under the given geological condition
