以下通过具体实施方式对本实用新型作进一步说明。 The following description of the present invention is further made to specific embodiments.

实施例:参见图1,采用一次反射的正投方式,投影幕是由左侧面1、右侧面2、前面3和底面4四个投影面构成,相邻的投影面之间相互垂直,每个投影面均为正方形。 Example: Referring to Figure 1, the use of a reflective front projection mode, the projection screen is 1, the right side surface 2, 3 and the bottom 4 in front of the projection surface is constituted by four left side face, perpendicular to each adjacent projection, each projection are square.

图1、图2所示,在左侧面1、右侧面2和前面3各投影面上采用背投方式,左侧投影机5、右侧投影机6和前方投影机7分别独立设置在左侧面1、右侧面2和前面3各投影幕的背部。 1, FIG. 2, a left side surface, right side surface 2 and the front surface of each projection 3 using projection mode, the left side of the projector 5, and 6 right in front of the projector the projector 7 are independently provided a left side surface, right side surface 2 and the back 3 of each front projection screen. 对应于每个投影面仅在中央位置上设置一只投影机;各投影机由投影机架固定设置,高度为放置投影机之后,保证投影机镜头处于投影面高度的1/2位置处,由于采用定焦镜头,因此,投影面与投影机之间的距离是一个固定值。 Provided corresponding to each of a projector in a central position on the projection surface only; the projectors rack is fixed by the projection, the projector height after placement, to ensure that the projector lens is at a position of 1/2 of the height of the projection, since the use fixed-focus lens, and therefore, the distance between the projection plane and the projector is a fixed value.

图1、图3所示,在底面4的投影面上,采用一次反射的正投方式,设置反射板8,在反射板8的入射位置处设置顶部投影机9。 As shown in FIG. 1, FIG. 3, the bottom 4 of the projection plane, is cast using a reflection mode, a reflective plate 8, 9 is provided at the top of the projector is incident at a position of the reflection plate 8. 具体实施中,顶部投影机9通过一个衍架加装在顶部,反射板8是与底面成45°的镜面。 In particular embodiments, the top of the projector through a truss 9 installed at the top, the bottom surface of the reflecting plate 8 into a mirror is 45 °.

为了给参与者提供较强的沉浸感,投影装置必须覆盖参与者的全部视野。 In order to provide a strong sense of immersion to the participant, the projection apparatus must cover the entire field of view of the participants. 根据人们的视野角度,可以计算出能够覆盖人们视野的投影幕高度到少为2.3米。 The people viewing angle, can be calculated to cover the horizon projection screen to a height of at least 2.3 m. 由于投向底面的投影机光束来自参与者的头顶部正上方,所以由于参与者遮挡形成的阴影较小,不影响参与者的正常观看。 Since the light beam toward the bottom surface of the projector directly above the top of the head from the participants, the shadow due to the occlusion formed smaller participants, the participants do not affect normal viewing. 整个投影系统可以完全包围参与者的正常视野。 The projection system may completely surround the entire field of view of normal participants.

参见图4,投影幕设置为双包围盒结构,由外层幕架10和内层幕布11固定连接为一整体结构,外层幕架10全尺寸大于内层幕布11,外层幕架10为钢结构,其表面喷涂为黑色,内层幕布11在左侧面、右侧面和前面三个投影面上为整体软幕。 Referring to Figure 4, projection screen bounding box is set to dual structure of an outer layer and an inner screen frame 10 is fixed to the curtain 11 a unitary structure, the outer curtain 10 full size frame is greater than the inner screen 11, outer screen frame 10 is steel, which is black surface coating, the inner layer 11 is integrally soft screen curtain on the left side, right side and three front projection surface. 这种结构形式保证了外层幕架10在固定内层幕布11的同时,不影响投影幕之间的接缝,不会对背投光线形成遮挡,同时,黑色有效保证了对于多余投影光的吸收,以及避免了不必要的漫反射。 This structure ensures that the outer screen while fixing the inner frame 10 of the screen 11, do not affect the seam between the projection screen, rear projection is not formed on the light blocking, while ensuring the effective black light for projection excess absorption, and to avoid unnecessary diffuse reflection.

具体实施中,投影机采用工程用投影机,配用相应的短焦镜头,f小于等于1.2的投影机,流明数在3000以上,可以实现在较短距离上背投成像。 Particular embodiment, the rear image projector uses engineering projector, equipped with corresponding short-focus lens, f the projector 1.2 or less, more than 3000 lumens, may be implemented over a shorter distance. 底部投影机采用普通的投影机,f在1.7-2.3之间,流明数在2000到3000之间,通过一次反射投影在底面上正投,通过反射装置保证从投影机镜头到底面的距离满足投影光路需求。 Bottom of the projector using a conventional projector, f between 1.7-2.3, lumens between 2000-3000, by one reflection surface of the projection is cast on the bottom, to ensure that in the end face of the distance from the projector by the projection lens satisfies the reflecting means optical path needs.
