【摘要】：利用光學(xué)成像原理,設(shè)計了基于機(jī)器視覺的雷達(dá)測角精度評估系統(tǒng),主要包括光學(xué)部分(CCD相機(jī))、圖像采集部分和圖像處理與目標(biāo)角度信息提取部分等;機(jī)器視覺的定位成像和高精度測角,保證了該系統(tǒng)能在緊縮場中對雷達(dá)系統(tǒng)進(jìn)行自動化、高精度、實(shí)時的角度測量校準(zhǔn)和測量精度評估試驗;理論分析和仿真結(jié)果表明,補(bǔ)償由于雷達(dá)系統(tǒng)和機(jī)器視覺系統(tǒng)安裝位置不同引起的角度測量偏差后,在正常的實(shí)驗測量誤差條件下,基于機(jī)器視覺的角度測量校準(zhǔn)和評估系統(tǒng)能達(dá)到O.005°的校準(zhǔn)和評估精度。
[Abstract]:Based on the principle of optical imaging, a radar angle measurement accuracy evaluation system based on machine vision is designed, which includes optical part (CCD camera), image acquisition part and image processing and angle information extraction part. The positioning and imaging of machine vision and high precision angle measurement ensure that the system can automate, high precision and real time angle measurement calibration and measurement accuracy evaluation test in the compact field. The theoretical analysis and simulation results show that, after compensating the angle measurement deviation caused by the different installation positions of radar system and machine vision system, under the normal experimental measurement error condition, The calibration and evaluation system of angle measurement based on machine vision can achieve the calibration and evaluation accuracy of 0. 005 擄.
