Abstract

The present invention discloses an auxiliary calibration device. The auxiliary calibration device may be configured to mount one or more calibration apparatuses. The auxiliary calibration device includes: a supporting frame; a guide rail, where the guide rail is mounted on the supporting frame; and a slider, where the slider is mounted on the guide rail, movable along the guide rail, and disposed to fasten a calibration apparatus used for calibration. The present invention may be applied to the field of auxiliary calibration devices of vehicles. By disposing a guide rail and a slider structure, the calibration apparatus required by calibration can be conveniently moved to a required position, thereby facilitating calibration for sensors of different types or sensors of a same type in different models of vehicles. Therefore, the auxiliary calibration device has a good commonality and is conveniently used.
