At first,we obtain binocular image outline by using Sombrero Function in different width,then we calculate the vision distance by using thezero crossingmethod. 先利用不同宽度的sombrero函数获取双目图像轮廓,然后用零相交法匹配获取视距,接着在物体三维信息恢复方面进行了一些探讨。

It is evident from the figure that increasing the signal threshold increases the distance between the time steps which will be executed. This often results in faster simulation times, but might reduce accuracy.
This means that the distance between consecutive zero-crossings also varies with time, and it is neither so that each second zero-crossing, i.e. a zero-crossing after one period, is located a time period of the alternating current after each other, i.e. in the case of 50 Hz 20 ms. ...
Based on the current theoretic calculation for the transmittance of the atmosphere, considering various factors such as height modification, slope distance and weather attenuation, an integrative theoretic model and the calculation method for the transmittance, average transmittance and integral transmittance ...
