The automobile product has a mature wind window key view division scheme due to the fact that the appearance consistency of the driving cab is good. In the engineering machinery industry, due to the fact that the types of products are multiple, and the types of cabs of different products are various, when the key visual field is determined, the existing dividing technology of the automobile industry is referred to more.

The visual field area division method is completely realized by means of a computer, is objective and is relatively universal in application. However, there are the following problems: before division, a three-dimensional model of a cab of a test object needs to be obtained, which is difficult to perform in an actual test, and special three-dimensional software is operated, so that requirements on full-time testers are high, and the test progress cannot be guaranteed; on the other hand, the method is more mature and applied to the automobile industry because the automobile cab is more uniform in form and the appearance of the windshield is more consistent. For engineering machinery products, due to the fact that the types of the products are multiple, the types of cabs are different, the composition of air windows of the cabs is complex, key areas of visual fields are different, and the difference between area division and actual requirements is large when the method is carried out. Secondly, the method is only suitable for front windshield division, and cannot divide a cab with multiple windwindows like a construction machine.
