The invention discloses a single-hole geological radar automatic drilling rig arranged at the cutter head center of a tunneling machine. The single-hole geological radar automatic drilling rig comprises an equipment entrance and exit hole, a rapid drilling machine, a borehole geological radar detection device and a carrying device, wherein the equipment entrance and exit hole is located at the cutter head center of the tunneling machine, the rapid drilling machine for the synchronous operation of tunneling and drilling and the borehole geological radar detection device are arranged in the hole, the carrying device comprises a carrying device support and an initiative angle adjusting device for adjusting an included angle between a drill bit of the rapid drilling machine or a borehole radar antenna hydraulic expansion link and the rotating axis of a cutter head of the tunneling machine, and the rapid drilling machine and the borehole geological radar detection device move relative to the device support, and the carrying device support is connected to the cutter head of the tunneling machine by a spherical joint for an equipment entrance and exit pipeline. The single-hole geological radar automatic drilling rig has the beneficial effects that the synchronous operation of tunneling and drilling can be realized, and the included angle between the eccentric casing drilling bit or the borehole radar antenna hydraulic expansion link and the rotating axis of the cutter head of the tunneling machine is adjusted.

The invention provides a method for identifying range ambiguity and azimuth ambiguity of a ring-scan radar, and the method comprises the steps: building a position and energy corresponding model of arange ambiguity target and a real target of the ring-scan radar, and identifying whether a to-be-outputted target is a range ambiguity false alarm or not; whether a to-be-output target is an azimuth fuzzy false alarm is identified by establishing a position and energy corresponding model of a loop sweep radar azimuth fuzzy target and a real target, and if the target is a false alarm caused by thetwo kinds of fuzziness, the false alarm is eliminated, so that the false alarm rate of the system is reduced, and the confidence of radar detection of the target is enhanced.

The invention discloses a hollow out barrier detection device and method for a SLAM; the detection device comprises a main machine, a laser radar and a depth camera; the laser radar is used for detecting to obtain laser radar data; the depth camera is used for detecting to obtain simulation laser radar data; the main machine is used for processing data so as to obtain a detection result of a barrier with a hollow out structure; the method comprises the following steps: using the laser radar to detect so as to obtain laser radar data; using the depth camera to detect to obtain the simulation laser radar data; obtaining the detection result of the barrier with the hollow structure via data calculation and fuzzy logic determination. The detection device and method can analyze the detected data so as to determine whether barriers with hollow structures exist in a visual field scope or not, thus detecting barriers that cannot be detected by the laser radar, and making up the disadvantages that a conventional SLAM technology only uses the laser radar for detection. The hollow out barrier detection device and method can be widely applied in the image identification processing technical field.
