lens distortion

基本解釋

Reset: Clicking this button will reset the lens distortion model to its default state.
復(fù)位：點(diǎn)擊該按鈕將重置鏡頭畸變模型到默認(rèn)狀態(tài)。
Shows lens distortion workflow based on re-distorting and compositing with the original image .
顯示鏡頭失真的基礎(chǔ) 上重新扭曲和合成與原始圖像的工作流。
Because of zero distortion at the centre of image, parameter calibration and lens distortion correction of CCD camera and DLP projector is separated with the points in center and all the rest points.
該方法根據(jù)圖像中心附近點(diǎn)畸變量較小的性質(zhì)，利用中心附近點(diǎn)和全場(chǎng)視點(diǎn)對(duì)CCD相機(jī)和DLP投影儀的內(nèi)外部參數(shù)標(biāo)定和鏡頭畸變修正進(jìn)行分離。

However, these feelings never lasted long, because the shot would switch to another camera position which had worse contrast, or greater lens distortion, or shallower depth of field, and the illusion would be broken.

Furthermore, we have achieved a wide horizontal viewing angle of 45 degrees by incorporating an optical lens that thoroughly suppresses unwanted elements such as aberration and distortion.

鏡頭畸變
It is very important to correct the camera lens distortion fo. getting the precise image and locating the correct po- sition of the object in robot vision detection and auto selection.
在機(jī)器人視覺檢測(cè)及自動(dòng)化分撿中,準(zhǔn)確地校正攝像機(jī)鏡頭畸變對(duì)獲取物體精確圖像及確定物體準(zhǔn)確位置具有重要意義。

Calibration method is crucial for the results of 3D vision measurement system. Therefore, this thesis introduces an effective calibration method, which takes lens distortion into account, to meet the need of high-accuracy 3D measurement.
在三維視覺測(cè)量中,標(biāo)定方法對(duì)測(cè)量結(jié)果的影響是決定性的,本文通過分析、比較各種視覺模型及標(biāo)定方法,采用考慮鏡頭畸變因素的三維視覺模型以滿足高精度測(cè)量系統(tǒng)的需求,并采用兩步法實(shí)現(xiàn)攝像機(jī)參數(shù)標(biāo)定過程。
