Meanwhile, the plate-shaped object 1 separates the mobile terminal 2 from the tested surface 3, and abrasion or pollution caused by direct contact of the mobile terminal 2 with the tested surface 3 is prevented. The planes of the upper surface and the lower surface of the plate-shaped object 1 are parallel to each other, so that the mobile terminal 2 is guaranteed to be strictly parallel to the measured surface 3, and the accuracy of a measurement result is guaranteed. In addition, the intelligent mobile phone is quite common, does not need to be purchased separately, is lower in cost than other professional instruments, can realize digital accurate measurement, and has a high practical value.
Specifically, as shown in fig. 6, the tilt angle reading of the mobile terminal 2 is read, and the read value is the value of the tilt angle α of the measured surface 3.

The camera housing employs a recess 11, the length of the plate 1 is greater than the width, and the length is greater than 100 mm and less than 200 mm.

In this embodiment, the length and width of the through holes 13 are all greater than 50 mm; the plate 1 has a length greater than the width and a length greater than 100 mm and less than 200 mm. The advantages are that: the length and width of the back camera area of most smart phones are not more than 50 mm, and the through holes 13 can basically ensure that all smart phones are applicable; the size of the plate-shaped object 1 can basically meet the requirements of all intelligent mobile phones, and can also meet the requirements of most tablet computers, and if the size is bigger, one of the plates wastes resources, and the two plates are inconvenient to carry.
