物体侦测系统及方法 Object detection system and method

技术领域 FIELD

[0001] 本发明是关于一种物体侦测系统及方法,特别地,本发明是关于一种利用不同时形成的光域(non-coincident fields of light)以及单一条直线式影像传感器(line image sensor)的物体侦测系统及方法。 [0001] The present invention relates to an object detection system and method, in particular, the present invention is the optical domain (non-coincident fields of light) is formed on a different time, as well as the use of a single linear image sensor (line image sensor) of the object detection system and method.

背景技术 BACKGROUND

[0002] 由于触控式屏幕(touch screen)能让操作者直觉地透过接触方式进行相对显示器的坐标输入的优点,触控式屏幕已成为现今显示器常见配置的输入装置。 [0002] Due to the touch screen (touch screen) allows the operator to intuitively coordinate input relative to the advantage of the display through the contact method, touch-screen input device has become common nowadays monitor configuration. 触控式屏幕以广泛地应用于各类具有显示器的电子产品中,例如,监视器、笔记型计算机、平板计算机、自动柜员机、销售点终端机、游客导览系统、工业控制系统,等。 Touch-screen electronic products to be widely used in various types with a display, for example, monitors, notebook computers, tablet computers, automated teller machines, point of sale terminals, tourist navigation systems, industrial control systems, and so on.

[0003] 除了传统电阻式、电容式等操作者必须接触的触控屏幕外,利用摄像组件(image-capturing device)让操作者无需真正接触到显示器的坐标输入方式也已被采用。 [0003] In addition to the traditional resistive, capacitive, and so the operator must contact the touch screen, use the camera module (image-capturing device) allows the operator to coordinate input without actually touching the display mode has been adopted. 利用摄像组件的非接触式触控屏幕(或称为光学式触控屏幕)的相关先前技术请见美国专利公告号第4,507,557号专利,在此不多做赘述。 The use of non-contact imaging components touch screen (or called optical touch screen) related to the prior art, see US Patent Publication No. No. 4,507,557 patent, not much to do in this repeat. 上述以光学影像方式,达成物体位置判断的物体侦测系统除可应用于触控屏幕外,也可以应用于触控绘图板、触控控制器等。 Mode optical image above to reach the object detection system to determine the position of the object can be used in addition to the touch screen, but also can be applied to touch the drawing board, the touch controller.

[0004] 为了更准确解析输入点的位置甚至能支持多点输入,关于光学式触控屏幕的先前技术,已有多种不同光源型态、光反射组件与导光组件的设计方案被提出,以提供更多关于输入点位置的角函数,以利准确地解析输入点的位置。 [0004] In order to more accurately resolve the position of the input point can even support multi-point input, the optical touch screen on the prior art, there are a variety of different light patterns, light reflection component and the design of light guiding means have been proposed, to provide more information on the angular position input function to facilitate accurate analytical position of the input points. 例如,美国专利公告号第7,460,110 号专利,其揭露利用具备辐射发光源的对象落在指示区域内,并且配合一片波导组件(waveguide)以及装设波导组件两边缘的反射镜,进而造成上、下两层且同时形成的光域(coincident fields of light),藉此摄像单元可以同时撷取上、下两层不同的影像。 For example, U.S. Patent Publication No. Patent No. 7,460,110, which includes the use of radiation to expose the light emitting source of the object falls within the indication area, and with a waveguide assembly (waveguide) and the installation of both edges of the mirror waveguide component, and then causing the optical domain, and the two formed simultaneously (coincident fields of light), whereby the camera unit can simultaneously capture the upper and lower layers of different images.

[0005] 然而,若要同时撷取上、两层不同的影像,摄像单元必须采用成本较高的矩阵式影像传感器(area image sensor)、多重直线式影像传感器(multiple-lineimage sensor)或两条直线式影像传感器。 [0005] However, to capture the same time, two different images, the camera unit must use higher-cost matrix image sensors (area image sensor), multiple linear image sensor (multiple-lineimage sensor) or two linear image sensor. 此外,采用矩阵式影像传感器、多重直线式影像传感器或两条直线式影像传感器,光学式触控屏幕需要耗费较多的运算资源才能解析这些影像传感器所撷取的影像,尤其是采用矩阵式影像传感器。 In addition, the use of a matrix image sensor, multiple linear image sensor or two linear image sensors, optical touch screen takes more computing resources to resolve these image sensors to capture the image, especially the use of a matrix image sensor. 此外,采用矩阵式影像传感器、多重直线式影像传感器或两条直线式影像传感器,光学式触控屏幕其系统组装所造成的误差会导致这些影像传感器感测到错的光域或感测不到光域的情况,尤其是采用两条直线式影像传感器。 In addition, the use of a matrix-type image sensor, the error of multiple linear image sensor or two linear image sensor, an optical touch screen system assembly caused by its cause these image sensor senses the wrong light sensing domain or not case the optical domain, in particular the use of two linear image sensor.

[0006] 此外,根据美国专利公告号第7,460,110号专利的光学式触控屏幕需具备辐射发光源的对象、波导组件与反射镜,三者同时搭配才能达成上、下两层且同时形成的光域。 [0006] In addition, according to the US Patent Publication No. No. 7,460,110 patented optical touch screen need to have radiation emitting source object, waveguide components and mirrors, with three at the same time in order to reach the upper and lower layers and while the optical domain formation. 明显地,美国专利公告号第7,460,110号专利的架构较为复杂。 Obviously, US Patent Publication No. No. 7,460,110 patent is more complex architecture. 而且,关于光学示触控屏幕的先前技术,其摄像单元对指示区域的辨识范围以及落在指示区域内的对象的分辨率,仍有待提升。 Moreover, with regard to the optical diagram of the prior art touch screen, which imaging unit of the resolution range of the indication region and the identification indication area falls within the object, to be improved.

[0043] 以下将以两个输入点(P1、P2)落于图IA中指示平面10内并藉由第一摄像单元16 及第二摄像单元18为例,藉以说明根据本发明的物体侦测系统1其在不同时间形成光域以及撷取的影像情况。 [0043] The following will be two input points (P1, P2) fall within a plane 10 in FIG. IA and indicating by the first image pickup unit 16 and the second imaging unit 18 as an example, in order to illustrate the present invention in accordance with the object detection an optical system 1 and the image domain case formed captured at different times.

[0044] 如图2A所示,图中实线代表在TO时间点控制单元11控制驱动第一发光源142及第三发光源152发射第一光以形成第一光域,且Pl及P2两输入点阻碍第一光逆向反射至第一摄像单元16及第二摄像单元18的路径。 [0044] shown in Figure 2A, the solid line represents the point in time TO the control unit 11 controls the driving of the first light emitting source 142 and the third light emitting source 152 emits a first light to form a first light field, and Pl and P2 two a first input point obstruct reflected light to the first reverse path 16 and the second image pickup unit 18 of the imaging unit. 图2A中的点虚线代表在Tl时间点控制单元11驱动第二发光源144及第四发光源154先行发射第二光以先形成第二光域,且Pl及P2 两输入点阻碍第二光逆向反射并正规反射至第一摄像单元16及第二摄像单元18的路径。 Dotted line in Figure 2A represents time Tl 11 drives the control unit 144 of the second illumination source 154 and a fourth light-emitting source emitting a second light to the preceding first forming a second light field, and the two input points Pl and P2 of the second light obstruction retroreflective and regular reflection path 16 to the first image pickup unit and the second image pickup unit 18.

[0045] 同样示于图2A,Pl及P2两输入点在TO及Tl两时间点阻碍第一光及第二光反射至第一摄像单元16的路径分别形成Φ2、Φ1、Φ4及Φ3四个角向量。 [0045] Also shown in FIG. 2A, Pl and P2 and the two input node of the first optical path of the second light reflection to the first image pickup unit 16 in the two time points TO and Tl are formed hindered Φ2, Φ1, Φ4 and Φ3 four angle vector. 如图2Β所示,在TO时间点,第一摄像单元16撷取关于第一光域的影像II,其上具有对应角向量Φ2及Φ1的实像阴影。 FIG 2Β shown at TO time point, the first imaging unit 16 capture the image on the first light domain II, having thereon a real image corresponding to the shadow angle of the vector Φ2 and Φ1. 在Tl时间点,第一摄像单元16撷取关于第二光域的影像12,其上具有对应角向量Φ4及Φ3的镜像阴影。 At time point Tl, the first imaging unit 16 capture the image on the second optical region 12, which corresponds to the angle of the vector having a shadow Φ3 Φ4 and of the mirror. 由于Pl及P2两输入点在第二光域中,同样会在影像12上造成具有对应角向量Φ2及Φ1的实像阴影。 Because of the two input points Pl and P2 in the second optical domain, it will also cause the image 12 has a corresponding angle vector Φ1 Φ2 and real image of shadows. 为了减轻运算资源、缩短处理时间,在Tl时间点,第一摄像单元16仅撷取对应第一边缘102的子影像,对应第二边缘104的子影像则不撷取,所以,图2B中所示的影像12上除了对应角向量Φ4及Φ3的镜像阴影之外,还有对应角向量Φ 2的实像阴影,但没有对应角向量Φ 1的实像阴影。 In order to reduce computing resources, reduce processing time, at the point of time Tl, the first image pickup unit 16 to retrieve only the first edge 102 corresponding to the sub-images, corresponds to the second edge 104 of the sub-image capture is not, therefore, in FIG. 2B 12 shows the image of the shadow of the mirror in addition to the vector and Φ3 Φ4 corresponding angle, there is a real image corresponding to the shadow angle vector Φ 2, but no real image corresponding to the shadow of a vector Φ angle.

[0046] 同样示于图2Α,Pl及Ρ2两输入点在TO及Tl两时间点阻碍第一光及第二光反射至第二摄像单元18的路径分别形成θ 2、θ 21、θ 24及θ 23四个角向量。 [0046] Also shown in FIG 2Α, Pl and Ρ2 two input points at two time points TO and Tl impede the first light and the second light reflected to the imaging unit 18 of the second path are formed θ 2, θ 21, θ 24 and the four corners of the vector θ 23. 如图2C所示, 在TO时间点,第二摄像单元18撷取关于第一光域的影像13,其上具有对应角向量θ 22及θ 21的实像阴影。 2C, at the time point TO, the second imaging unit 18 capture the image on the first light field 13, which corresponds to the angle vector θ having a real image of the shadow 22 and θ 21. 在Tl时间点,第二摄像单元18撷取关于第二光域的影像14,其上具有对应角向量θ 24及θ 23的镜像阴影。 At time point Tl, the second imaging unit 18 capture the image on the second optical region 14, on which a vector having a corresponding angle θ 24 and θ 23 of the shadow image. 由于Pl及Ρ2两输入点在第二光域中,同样会在影像14上造成具有对应角向量θ 22及θ 21的实像阴影。 Because Pl and Ρ2 two input points in the second optical domain, it will also result in the shadow of the real image with a vector θ 22 and θ 21 corresponding angle in the image 14. 为了减轻运算资源、缩短处理时间, 在Tl时间点,第二摄像单元18仅撷取对应第一边缘102的子影像,对应第四边缘108的子影像则不撷取,所以,图2C中所示的影像14上除了对应角向量Θ24及Θ23的镜像阴影之外,还有对应角向量θ 22的实像阴影,但没有对应角向量θ 21的实像阴影。 In order to reduce computing resources, reduce processing time, at the point of time Tl, the second image pickup unit 18 to retrieve only the first edge sub-image corresponding to 102, corresponding to the fourth edge 108 of the sub-image capture is not, therefore, FIG. 2C 14 in addition to the image shown shaded Θ24 and Θ23 vector image corresponding angle, there is a real image corresponding to the angle vector θ shadows 22, but there is no corresponding vector θ real image 21 of the shadow angle.

[0047] 明显地,藉由解析影像II、影像12、影像13以及影像14上阴影所指示的角向量, 根据本发明的物体侦测系统1可以准确地计算出图2Α所示Pl及Ρ2两输入点的位置。 [0047] Obviously, by parsing image II, 12 images, 13 images, and the images on the vector angle indicated by the shadow 14, the object detection system according to the present invention can accurately calculate a showing Pl and Ρ2 two shown 2Α Enter the location of the point. 更需强调的是,根据本发明的第一摄像单元16及第二摄像单元18皆可以是单一条直线式影像传感器。 More should be emphasized that, according to the present invention is the first image pickup unit 16 and the second image pickup unit 18 may be a single both a linear image sensor. 藉此,根据本发明的物体侦测系统可以不必采用昂贵的影像传感器,其组装上也能避免影像传感器感测到错的光域或感测不到光域的情况。 This makes it possible without the use of expensive image sensor object detection system according to the invention, the assembly thereof can be avoided to the image sensor senses the light field or error is less than the light-sensing domain. 本发明与先前技术最大不同之处在于:1.以镜像的方式,增加摄像单元可以完全辨识指示区域的范围;2.增加摄像单元与指示区域边隅的光程距离,如此可避免当对象接近隅角时,分辨率低落甚至无法辨识的困难;3.对象实像与镜像光影在摄像单元的成像不分层;4.使用两组不同波长的光源;5.物件本体无须发光;6.与先前技术需具备辐射发光源的对象、波导组件与反射镜三者同时搭配相较下,本发明的架构相对简易。 The present invention and the prior art, the biggest difference is that: a way to mirror the increased range of the camera unit can fully identify the indication region; 2 indicates the region to increase the imaging unit with optical drive from the edge of the corner, so to avoid when approaching object. When the upper corner, difficult or even impossible to identify low resolution; 3. real image of the object is not hierarchical and mirror light imaging camera unit; 4 using two different wavelengths of light; 5 items without luminous body; 6 and earlier. Object technology need to have radiation emitting source, the waveguide components and mirrors compared with three at the same time, the structure of the present invention is relatively simple.
