Abstract

The invention relates to a measurement apparatus and a measurement apparatus for attitude of a self-walking underground tunneling robot, and belongs to the navigation positioning field during an underground tunneling process of a robot. A system comprises two emitters rotating at a certain angular speed and a plurality of receivers. A world coordinate system corresponding to a tunneling robot route is established through an electronic compass module and a leveling pedestal. The emitters emit three laser beams comprising one gated laser beam and two sector laser beams. Horizontal angles and pitching angles of the receivers relative to a horizontal plane of the two emitters are calculated by using geometrical relationships among the laser beams, rotational speed of the emitters, coordinate positions and time difference that the laser beams are received after the laser beams are received by the receivers. The measurement apparatus and measurement apparatus have the advantages of simple operations, low cost, convenience for maintenance and high positioning precision. Besides, the measurement apparatus and measurement apparatus not only can be used for the underground pose measurement but also can be used on the ground or for position and path measurement of spatial coordinates of a moving point.

Description

technical field [0001] The invention belongs to the technical field of navigation and positioning in the excavation process of an underground robot. Background technique [0002] The traditional self-propelled underground excavation robot pose measurement method is manual measurement, using a total station to measure the coordinates of multiple prisms installed on the robot body, and then according to the geometric relationship between the prism and the axis of the excavation robot measured before the measurement, The underground excavation pose of the robot can be calculated. This method has high precision, but the operation is complex and time-consuming, and it cannot be measured during the excavation process, and its real-time performance is weak. [0003] With the development of technology, there are two positioning methods based on automatic total station navigation and positioning and inertial navigation system. For the navigation and positioning of the automatic tot...
