In view of the insufficient characteristics and depth acquisition difficulties encountered in process uniocular vision measurement, posture measurement scheme tunneling equipment based on was proposed this study. The positioning coal mine monocular to extract environmental features match features, RANSAC algorithm used eliminate pair mismatching points. This done solve optimized matching realiz...

Pose measurement of coal mine excavation equipment is an important part roadway excavation. However, in the underground mining mine, there are some influencing factors such as low illumination, high dust and interference from multiple equipment, which lead to difficulty position pose roadheader with accuracy poor stability. A combination positioning method based on machine vision optical fiber ...

As the working efficiency and life span of shovel plate a roadheader directly influence its performance, optimization shovel-plate parameters is crucial. For optimizing parameters, variations in loading capacity grubbing force with respect to are determined this study. Moreover, ideal point method gray weight proposed for multiobjective optimization. The weights resistance by investigating exis...
