AI Technical Summary

Technical Problem

When the prior art performs the inspection of the enclosure box within the specified range within the construction machinery working area, the method is cumbersome and error-prone, and it is impossible to quickly and accurately obtain the enclosure box within the specified range and the highest enclosure box within the area.

Method used

By converting the coordinates of each vertex coordinate of the enclosure box of the obstacle in the construction machinery working area, converting it from the spatial rectangular coordinate system to the column coordinate system, the pole diameter, pole angle and height values ​​of the vertices of the enclosure box are obtained. Then, the coordinate range of the enclosure box on the radial axis, height axis and angle axis is determined based on these values, and these ranges are compared with the specified range to obtain the enclosure box detection results within the specified range.

Benefits of technology

It realizes the rapid and accurate detection of the positional relationship between the boundary of the enclosure box and the area boundary, obtains the boundary box within the specified range and the highest boundary box within the area, thereby providing necessary obstacle information for trajectory planning and ensuring the safety of construction machinery.
