360-degree stereo imaging underground pile hole wall detection instrument

The invention provides a 360-degree stereo imaging underground pile hole wall detection instrument. The 360-degree stereo imaging underground pile hole wall detection instrument comprises a measurement and control computer, a winch and a probe; the measurement and control computer is used for generating a probe control signal of the probe according to information input by a user and transmitting the probe control signal to the winch; the winch controls the probe to start transmitting and receiving of ultrasonic waves according to the probe control signal and controls the probe to move in an underground pile hole; the probe extends into the underground pile hole, lifting and ultrasonic wave transmitting are carried out under control of the winch, the probe is controlled to rotate according to the ultrasonic wave time difference, and the measurement and control computer draws a three-dimensional panoramic picture and/or a two-dimensional panoramic picture of the pile hole according to pile hole data. According to the 360-degree stereo imaging underground pile hole wall detection instrument, the 360-degree rotation detection mode is adopted; compared with a traditional fixed detection mode, more abundant lateral wall information can be obtained, tiny holes and tiny cracks, which cannot be detected by an instrument at present, in the lateral wall can be detected.
