The embodiment of the invention discloses a dual-camera test device and method, belonging to the technical field of camera test. The device comprises: a calibration test module comprising a first codescanning unit and a calibration unit, wherein the first code scanning unit is configured to perform code scanning of an object to be tested equipped with double cameras to establish first communication connection between the dual-camera test device and the object to be tested, and the calibration unit is configured to perform calibration of the double cameras of the object to be tested; and a mechanical arm configured to convey the object to be tested to the calibration unit and out of the calibration unit. The dual-camera test device and method employs the first code scanning unit to performcode scanning of the object to be tested to establish data connection, and employs the calibration unit to perform calibration of the object to be tested with no need for manual operation of operators so as to effectively improve the test precision and the test efficiency, the automatic test replaces the manual test to reduce the manual operation link of operators, avoid that the test is blockedor the test result is not accurate due to human errors and achieve test poka yoke.
