In another embodiment, the camera 31 and the sliding block 35 are fixed, and the screw 32 performs telescopic movement under the action of the motor 34, so as to realize the longitudinal position change of the camera 31. However, the imaging device 3 may adopt various moving methods, and is not limited to the embodiment disclosed in the present application.

In one embodiment as shown in fig. 1 and 2, the viscometer 4 and the camera 3 are arranged in a one-to-one correspondence, and the length of the viscometer 4 is less than or equal to the length of the screw 32, so as to ensure that the camera 3 can acquire any position reading of the viscometer 4 in the length direction. The screw 32 is provided in parallel with the viscometer 4, and the camera 31 is provided corresponding to the capillary of the viscometer 4.

When the asphalt sample begins to fall in the viscometer, the camera automatically identifies and tracks the asphalt liquid level, and feeds back the information recorded in real time to an output interface. When the height of the liquid level in the viscometer reaches the timing requirement, a tester presses a timing button to record time, and the experiment is completed.
