Calibration verification assembly, system and method

The invention relates to a calibration verification assembly, system and method, belongs to the technical field of sensors, and the calibration verification assembly and system can be applied to intelligent automobiles in the field of automatic driving. The calibration verification assembly comprises a first detection object (1), a second detection object (2) and a support (3). The first detection object (1) and the second detection object (2) are objects used for being detected by different types of sensors (7) respectively; the first detection object (1) and the second detection object (2) are respectively arranged on the support (3). In the embodiment disclosed by the invention, the first detection object (1) or the second detection object (2) can be accurately identified by at least one sensor (7), so that the situation that the identification precision of different types of sensors (7) on the same target reference object is greatly different in the prior art is avoided, and the calibration verification p
