The utility model relates to a non-contact angle measurement device based on a mobile terminal, and belongs to the technical field of measurement. The feedback type automatic adjusting assembly is insignal connection with the control unit and comprises a rotating motor and at least two distance sensors; the image acquisition unit is connected with the rotating motor, and the image acquisition unit is driven to rotate when the rotating motor rotates so as to adjust the angle between the image acquisition unit and an object to be measured; the image acquisition unit is also in signal connectionwith the control unit; the problem that the rotation angle of the object cannot be accurately measured can be solved; since the image of the to-be-measured object is acquired only when the distance data acquired by the at least two distance sensors are equal, it can be ensured that the plane where the image acquisition unit is located is parallel to the plane where the to-be-measured object is located, and the accuracy of
