ROADHEADER FOOTAGE MEASUREMENT METHOD

摘要

A roadheader footage measurement method, relating to the technical field of footage measurement. According to the measurement method, a distance measurement apparatus (2) and a reflecting target (1) are provided, a laser beam is emitted from a laser sensor (21) to the reflecting target (1), and the laser beam which is reflected by the reflecting target (1) is received, and the time from emission of the laser beam to reception thereof is measured by means of a timer, so as to calculate the distance L from the laser sensor (21) to the reflecting target (1) in order to automatically measure the roadheader footage; and at the same time, a return-light quantity C is monitored, and whether the laser beam hits the target is determined according to the return-light quantity, so as to start a targeting process in good time. According to the roadheader footage measurement method, the roadheader footage is automatically measured by means of arranging the distance measurement apparatus (2) and the reflecting target (1), and manual measurement is replaced with automatic measurement, such that the measurement precision is high, and the labor intensity is reduced; and at the same time, whether the laser beam hits the target can be determined according to the return-light quantity measured by the laser sensor (21), so as to start a steering engine gimbal (23) according to requirements to perform targeting, thereby further improving the accuracy and integrity of distance measurement.
