摘要：混凝土裝載機(jī)進(jìn)行成品料卸料前的出料口位置視覺(jué)校準(zhǔn)是進(jìn)行混凝土裝載的重要的一步，目的是通過(guò)計(jì)算機(jī)視覺(jué)系統(tǒng)，保證處于空間位置的出料口中心和處于固定位置的運(yùn)輸車(chē)裝料口中心重合。研究出一種采用人機(jī)交互的方法，實(shí)驗(yàn)結(jié)果證明該方法可實(shí)現(xiàn)裝/卸料口的準(zhǔn)確定位，縮短了圖像處理的時(shí)間，提高了混凝土卸料的速度。

Before unloading of cement, a key step is the position calibration of the comment loading and camion. Its target is to eliminate the position errors between the center of the comment loading head and the center of the vision area so as to unload accurately. This paper presents a novel approach, using man-computer interaction to realize the position calibration. It can save time and improve speed.
