Embodiment Construction

[0025] The present invention provides an object detection system and method for optically detecting the target position of the object on the indicating plane. In addition, the object detection system and method according to the present invention can detect object information such as object shape, object area, object three-dimensional shape and object volume in the indication space including the indication plane. And in particular, object detection systems and methods according to the present invention utilize light fields that are not formed simultaneously. Therefore, the object detection system and method according to the present invention can be implemented by using a lower-cost image sensor and less computing resources. The following is a detailed description of preferred embodiments of the present invention to fully illustrate the features, spirit, advantages and practical feasibility of the present invention.

[0026] see Figure 1A and Figure 1B , Figure 1A is a sche...

Abstract

The invention provides an object sensing system and an object sensing method, which are used for sensing object information of an object in an indicated space, such as a target position of the object on an indicated plane. Particularly, images related to the indicated space are captured from images of optical domains formed asynchronously, and the object information of the object in the indicatedspace is determined according to the captured images.

Description

technical field [0001] The present invention relates to an object detection system and method, in particular, the present invention relates to an object detection system utilizing non-coincident fields of light and a single line image sensor Object detection system and method. Background technique [0002] Due to the advantage that the touch screen allows the operator to intuitively input coordinates relative to the display through contact, the touch screen has become a common input device for displays today. Touch screens are widely used in various electronic products with displays, such as monitors, notebook computers, tablet computers, automatic teller machines, point-of-sale terminals, visitor guidance systems, industrial control systems, and so on. [0003] In addition to the traditional resistive and capacitive touch screens that the operator has to touch, a coordinate input method that uses an image-capturing device so that the operator does not need to touch the dis...
