參照 1 力本 的 像 的 的第 的 像 的 包含有框架 101、紅外 像 102、反光 103及 104 反光 103安裝在 裝有紅外 像 102的 余框架 上 至少 外 像 102的 覆蓋反光 103。在固 1所示的 The first of the image of the image The image includes a frame 101, an infrared image 102, reflective lights 103 and 104. The reflective light 103 is mounted on the remaining frame containing the infrared image 102 to cover at least the outer image 102. As shown in solid 1
外 像 102有 分別安裝在 反光 103相 的框架 的 ， 外 像 的 角力 90 ，反光 103的未 其所在框架 的未 相同。 中所示的 摸魚A的位置 于 外 像 102 同的 哉 B的位置 于紅外 像 03附近， 的位置 在現有 像 屏中都局于 但在本 A 在反光 103中生成投影 a， B 在反光 103中生成投影b， 很容易通 三角定位法 投影a、 b的位置， 內 理 統 的分析、 ， 就可以得出 A、 B的位置。 位置不 于 ， 外 像 直接通 三角定位法就可以 物的位置。 其 弧形 哉 105的 紅外 像 的 哉 106 投影的 哉， 中 同的 紅外 像 的 。 的 像 的 裝了 介反光 就消除了 像 的 而且 成本低廉 于大批量生 。  The outer image 102 is mounted on the frame of the reflective 103 phase, and the angular force 90 of the outer image is not the same as that of the frame 103 of the reflective image 103. The position of the fish A shown in the image 102 is the same as the position of the 哉B of the outer image 102 near the infrared image 03. The position of the fish A is in the existing image screen, but in the present A, the projection a is generated in the reflection 103, and B is reflected. The projection b is generated in 103, and it is easy to project the positions of a and b by the triangulation method, and the analysis of the internal system can obtain the positions of A and B. The position is not the same, and the outer image can be directly positioned by the triangle positioning method. The curved image of the 哉105 of the 哉105 is projected by the 哉106, in the same infrared image. The image of the image is reversed and the cost is low and the mass is produced.
參照 2 力本 的 像 的 的第二 的  The second of the image of the 2
像 的 1所示的 像 的 的不同 在于 紅外 像 102同 安裝在 反光 103相 的框架 上， 外 像 102的 覆蓋反光 103 紅外 像 102的 小于90 。 由于反 光 103的未 其所在框架 的未 相同 則 104在 反光 中在反光 103中形成投影 201， 104上的任何  The image shown in Fig. 1 differs in that the infrared image 102 is mounted on the frame of the reflective 103 phase, and the outer image 102 covers the reflective image 103 of the infrared image 102 of less than 90. Since the mirror 103 is not the same as the frame, the 104 forms a projection 201, 104 on any of the reflections 103 in the reflection.
同 也 在反光 103中形成投影， 中 及其投影 因 紅外 像 102的 都覆蓋反光 103， 則可以 三角定位方法 未 光 中投影"的位置， 通 理 統 、 分析就可以得到  Similarly, the projection is formed in the reflection 103, and the projection and the projection thereof are covered by the infrared image 102, so that the position of the projection can be obtained by the triangulation method, and the analysis can be obtained by analyzing the system.

The image of the image is installed in a common position, the accuracy is eliminated, and the market is more competitive. 2a, solid 2b outer image 102 are respectively mounted on the frame of the reflective 103 phase or respectively An indication of the different positions on the phase frame equipped with the reflective light 103.
參照 3， 力本 的 像 的 的 的 化方 案 本 化方案是 上 所有 在 上的 化，在 裝有反光 103 的框架 上安裝有管 外光源 301。 其中 外光源 301可以用微稜 鏡反光余未代替， 只需將微稜鏡反光余 貼在沒有 反光 103的框架其 它 上即可。 送神 的 像 裝光源或反光余， 化了 紅外 像 的因像 效果 而提高了 精度。  Referring to Fig. 3, the embodiment of the image of the force image is all above, and the external light source 301 is mounted on the frame equipped with the reflection 103. Wherein, the external light source 301 can be replaced by a micro-mirror, and only the micro-reflective residue can be attached to the frame without the reflective 103. The image of the gods is equipped with a light source or a reflection, which improves the accuracy of the infrared image.
參照 4 力本 的 像 的 的第三 的  The third of the image of the image
像 的 包含有框架 101、 外 像 102及反光 103及 104， 反光 103安裝在 裝有 外 像 102的 框架 上， 紅外 像 102 介且 外 像 102的 覆蓋 The image includes a frame 101, an outer image 102, and reflective lights 103 and 104. The reflective light 103 is mounted on a frame on which the outer image 102 is mounted, and the infrared image 102 is covered by the outer image 102.
04和反光 03， 外 像 02附近安裝有 外平行光源40. 在 4所示的 中 紅外 像 102安裝在 反光 103相 框架 的 介 ，此紅外 像 的 角力 90 外平行光源401安裝在反 光 103 外 像 102 同的框架 上 外平行光源 401的光 平 行于反光 103。 由于 外 像 像需要 定的物 ， 果  04 and reflection 03, an external parallel light source 40 is installed near the outer image 02. The mid-infrared image 102 shown in Fig. 4 is mounted on the reflective 103 phase frame, and the angular force of the infrared image is 90. The parallel light source 401 is mounted on the reflective image 103. The light of the outer parallel light source 401 on the same frame is parallel to the light reflection 103. Because the external image needs to be fixed,
外 像 同的 萬 近就 外 像 像， 中所示的 摸 魚 于 現有的 像 是 到 摸魚 的 位置的， 但在本 中， 因 裝了 介反光 103 就能 到 摸魚 的位置， 消除了 。 摸魚 在反光 中 生成投影 The outer image is the same as the outer image. The fish shown in the image is in the position of the fish. However, in this book, the position of the fish can be removed by the installation of the reflective light 103. . Fish in the reflection
在 外平行光源 401的照射下 在框架 上形成 介阿 外 像 102 的位置就可以 的 你位 置。 于 外 ， 外 像共通  The position where the external image 102 is formed on the frame under the illumination of the outer parallel light source 401 is possible for your position. Outside and outside
在 外平行光源照射下 形成的 就可以 物的 位置。其中 反光 103的未 可 于其所在框架 的未 ， 只需 的寬度等 未即可 材料， 降低生 成本。 其中， 哉402 的 哉。 The position of the object can be formed by the illumination of an external parallel light source. Among them, the reflection 103 is not available in the frame, the width of the frame, etc., which is not available, and the production cost is reduced. Among them, the number of 哉402.
的 像 的 消除了 ， 羊 成本低， 于大批量生 。 本 不限于 休 方式中 的 ， 本領域 木 本 的 木方案得出的其他 方式，同 于本 的 木 新 固。 The elimination of the image, the sheep cost is low, and the mass is born. This is not limited to the way of rest, the other way of woodwork in this field is the same as that of this wood.
