The benchmarking module 2 is set to two groups, namely a first benchmarking module 2 and a second benchmarking module 2. The benchmarking module 2 is connected to the beam 4 of the vehicle to be tested. The data acquisition module 1 acquires the collected data by collecting the position information of the first benchmarking module 2 and the second benchmarking module 2, and detects the offset of the vehicle axle 3 by benchmarking the collected data.

[0019] Specifically, the data acquisition module 1 includes a visual sensor and a mounting frame connected to the visual sensor.

In this embodiment, the distance between the first benchmarking module 2 and the data acquisition module 1 should be no less than 1.5 meters to ensure that the data acquisition module 1 has a sufficient shooting distance so that the image information of the first benchmarking module 2 and the second benchmarking module 2 at a farther distance can be completely collected. On the other hand, in order to prevent the first benchmarking module 2 from blocking the second benchmarking module 2 during data collection, the heights of the first benchmarking module 2 and the second benchmarking module 2 are set to be unequal, so that the two are distributed in a staggered manner to ensure that the image information of both can be completely collected.
