The invention relates to an irregular hole circumference measurement and circumference and diameter detection device and method. A workbench is provided with a positioning clamp, and a measurement end is installed on the rotary workbench. The contact measurement is that firstly, a work piece is placed into the positioning clamp for fixing, a moving table cylinder on the rotary workbench pushes a probe holder so that a probe is in contact with a measuring surface, a servo system drives a rotary table to rotate, and a circular grating and a displacement sensor collect data at the same time. The non-contact measurement is that: firstly, the work piece is placed into the positioning clamp for fixing and falls in the measurement range of a laser displacement sensor on the rotary workbench, the servo system drives the rotary table to rotate, the circular grating and the displacement sensor collect data at the same time, and a data collection and communication system sends data to a data processing and displaying sy
