中文拼音 [jībiànchāzhí]
畸變差值
英文
differential distortion-
The measurement and alteration of ordinary digital camera. it includes the correction of lens distortion of digital cameras, the computing of camera interior orientation parameters and pictures " exterior orientation parameters, and the evaluation of it ' s capability ; 2
其中包括普通數碼影像畸變差的改正、數碼相機內方位元素的檢定、數碼近景攝影機的研製及外方位元素改正值的確定、普通數碼相機量測化性能評價; 2Integrated optomechanical analysis devides rigid - body and aberration, then computes the pv and rms. it provides guidance for design, tolerances allocation and alignment of optomechanical system. finally, abberations are converted to a sort of data form that can be imported by corresponding optical design software to observe their impact upon the optomechanical system imaging performance
光機集成有限元分析方法就是通過分離三種形式的剛體位移和光學表面畸變的pv值和rms值,指導光機系統的設計、誤差分配和裝調,並將數據轉換成光學分析軟體codev可接收的數據形式,對光機系統做整體成像性能評價。The detecting method of dvr is different from harmonic and reactive current detecting methods. it need detect not only total harmonic distortion but also the difference between fundamental wave component and reference value
Dvr的檢測方法與諧波、無功電流的檢測不同,不但需要檢測出除基波分量之外的總畸變分量,還要檢測出基波分量與基波基準值之差。This algorithm is to work out the correction table by using the theoretical data to contrast with the real data of the corresponding points in laser beams so as to correct the pillow - shaped distortion and other errors in terms of the interpolation algorithm
該演算法用理論數據與激光束在相應點的實際數據進行比對,製成校正表,按插值演算法校正實際的枕形畸變及其它誤差。According to this, we propose a new way to renew the traditional method of subjective image quality evaluation, different to only use mse ( mean square error ) and psnr ( peak signal - to - noise ratio ) to evaluate merely on radiation distortion, and complemented quantitative description on compressed image distortion o it is significant to choose the format of video transferation and measuring precision calculation of tracking and measuring systems based on images
中國科學院長春光機與物理研究所博士學位論文據此提出了不同於傳統的僅用均方誤差( mse )和峰值信噪比( psnr )來評價圖像灰度輻射畸變的新思路,補充了對壓縮圖像幾何畸變的定量描述。這對于基於圖像的測量跟蹤系統中數字圖像傳輸方式的選擇,以及評價壓縮解壓演算法對測量精度的影響有重要意義。In the modern power system, acute fluctuation of load lead to great difference of wave crest and trough, abundance non - linear load make severe aberrance of current and voltage wave. these factors make remarkable increase of error of energy metering and unrational billing
現代電力系統中,負荷波動劇烈使負荷峰谷差值很大,大量的非線性負荷使電流、電壓波形畸變嚴重,這些因素使電能計量誤差顯著增大,並使計費不合理。分享友人
