in the embodiment, a person sits on a sofa, the training instrument obliquely projects laser points and forms a training viewpoint with a wall surface, and the sight line of the person is vertical to the wall surface when the person looks upright

As shown in fig. 4, the five viewpoints are respectively denoted as a1 and an upper viewpoint; b1, lower viewpoint; c1, left viewpoint; d1, right viewpoint; e1, central viewpoint; the five laser range finders are respectively marked as A2 and the laser range finder corresponding to the upper viewpoint; b2, a laser range finder corresponding to the lower view point; c2, a laser range finder corresponding to the left viewpoint; d2, a laser range finder corresponding to the right viewpoint; e2, and a laser range finder corresponding to the central viewpoint.

As shown in fig. 5 and 6, the calculation for each viewpoint is schematically illustrated

The emitting light of each laser range finder is perpendicular to the same plane where the output shaft main lines of each second stepping motor 6 are located in the initial state, and because the installation center point of each second stepping motor 6 is on the same circle, the installation center point of one second stepping motor 6 is arranged at the center of the circle, and the other four are distributed on the circle up, down, left and right, the length A2E2 is known as B2E2 as C2E2 as D2E2 as X;

the distance from the upper viewpoint, the lower viewpoint, the left viewpoint and the right viewpoint to the central viewpoint is the same as the viewpoint formed on the wall surface of the training instrument, i.e. A1E1 is B1E1 is C1E1 is D1E1, but the distance value is variable and is marked as Y;

in addition, the distance from the laser range finder E2 corresponding to the central viewpoint E1 is known as E1E 2;

specifically, the value of Y needs to be determined firstly during use, and assuming that the position of a left viewpoint C1 is set, the positions of A1, B1 and D1 need to be determined by rotating second stepping motors on A2, B2 and D2, and the rotating angle is controllable by using stepping motors, so that the degree of E2C2C1 is known;

as shown in fig. 6, the known amount includes C1E1 ═ D1E1 ═ Y, C2E2 ═ D2E2 ═ X, ═ C2E 1 ═ D2E 1 ═ 90 °, < E2C1, distances C2C1, E2E1, and the unknown amount includes distances D2D1 and ═ E2D 1;

the calculation is carried out by using the triangle cosine law, which specifically comprises the following steps:

E2C1²＝C2C1²+X²the distance between E2C1 can be obtained by-2 XC2C1cos E2C2C 1;

E2C1²＝E2E1²+Y²the degree of < C1E1E2 can be obtained by-2 YE2E1cos < C1E1E 2;

∠D1E1E2＝180°-∠C1E1E2；

the length of E2D1 is obtained by applying the cosine law, then the degree of < E1E2D1 is calculated, the length of D2D1 is obtained by applying the cosine law when the < D2E2D1 is 90 DEG-E1E 2D1, and the degree of < E2D2D1 is calculated by applying the cosine law.

As shown in fig. 5, the known quantities include A1E1 ═ B1E1 ═ Y, A2E2 ═ B2E2 ═ X, A2E 1 ═ B2E 1 ═ A1E 2 ═ B1E 2 ═ 90 °, distance E2E1, the unknown quantities include a distance A2A1 ═ B2B1, and a distance A2A1 ═ E2B 1;

the & lt E2A2A1 and & lt E2B2B1 can be calculated by applying the cosine theorem in the same way.

In summary, when the position is determined by one of the viewpoints a1, B1, C1, and D1, that is, the length of Y is set, the positions of the other viewpoints can be calculated, which facilitates the automatic determination of the unknown viewpoints of the present invention.
