利用不同时形成的光域的物体侦测系统及方法 Object detection system and method utilizing the optical domain is not formed simultaneously

技术领域 FIELD

[0001] 本发明关于一种物体侦测系统及方法(object-detecting system and method),并且特别地,本发明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 a system and method for detecting an object (object-detecting system and method), and in particular, the present invention relates to a use of the light field (non-coincident fields of light) are not formed simultaneously, and 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.

[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)的相关现有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 relevant prior art touch screen (or called optical touch screen) can be found at the US Patent Publication No. 4,507, 557 patent, not much to do in this repeat.

[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现有技术,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 the light guiding means is made 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,其揭露利用一片波导组件(waveguide)以及装设波导组件两边缘的反射镜配合光源可以造成上、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 expose the use of a waveguide assembly (waveguide) and the installation of the waveguide reflection mirror assembly with both edges of the light field source can cause upper and lower layers and 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、下两层不同的影像,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-line image sensor)或两条直线式影像传感器。 [0005] However, to capture the same time, under two different images, you must use higher-cost matrix image sensors (area image sensor), multiple linear image sensor (multiple-line image 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.
