  • Implementation experiments on convolutional neural network

    For productivity estimation, the activities of the excavator are recognized, and then their time duration is calculated (e.g., the time required to excavate and dump a soil load into a truck) using a stopwatch. The productivity of the excavator is the ratio of the amount of excavated soil to the time duration for this excavation (e.g., m 3 /h).
