Description of the Invention: [Technical Field] The present invention relates to an object sensing device, and more particularly to an object sensing device that utilizes a feature pattern to determine a target distance of an object. [Prior Art] Since current consumer electronic products are designed in a light, thin, short, and small direction, there is no room for traditional input tools such as a mouse, a keyboard, and a stylus. With the advancement of touch device technology, in various material electronic products, such as display, All in One, mobile phone, personal digital assistant (Pu-Dang, lion), PDA, etc. Let Lai domain (4) be the tool for inputting its data. In addition, with the maturity of touch devices, electronic audio and video with large-size and multi-touch technologies has become a future social stream. At present, optical touch devices have advantages such as lower cost and easier to achieve compared to the conventional ones such as resistive, capacitive, ultrasonic or projected image. In general, the conventional optical touch device _ optically senses the position indicated by an object (e.g., a finger or a stylus). When the image sensing unit senses the object in the 4th plane, the position indicated by the object is not covered by the conventional optical touch sensing algorithm (for example, triangulation measurement). However, if the user refers to one or more positions at the same time on the touch screen, the situation may be misjudged due to the lack of distance information. 201218047 SUMMARY OF THE INVENTION One of the purposes of this month is to provide an object sensing device that determines the target distance of an object by using the optical 7L member to project on the object. According to an embodiment, the object sensing device of the present invention comprises an indication plane, a first illumination unit, a silk tree, a first image sensing unit and a control unit.

Further details of the advantages and spirit of the present invention will be apparent from the following detailed description of the invention. 5 201218047 [Embodiment] Please refer to Fig. 1 which is a schematic view of an object sensing device 1 according to a first embodiment of the present invention. As shown in FIG. 1 , the object sensing device 1 includes an indication plane 1 , a first illumination unit 12 a , an optical component 14 , a first image sensing unit 16 a , a control unit 18 , and a memory unit 2 . . The indicating plane 1 is used for an object 22 (eg, a finger or a stylus) to indicate that a target position target position p includes a target distance D between the object 22 and the first image sensing unit 16a and between the objects 22 A target angle A between one side s of one of the indicating planes 10. The first light sensing unit i2a and the first image sensing unit 16a are disposed around the indication plane 10, and the first image sensing unit 16a is adjacent to the first light emitting unit 12a. In this embodiment, the first light-emitting unit 12a and the first-image sensing early element 16a may be disposed at one corner of the indicating plane 1〇. The control unit 18 is electrically connected to the first image sensing unit (6), the first light unit 仏, and the memory unit 20. In practical applications, the first light emitting unit 12a may be a light emitting diode. It should be noted that the number of the first light-emitting units 12a can be determined according to the actual application, and is not limited to the one shown in the figure. The first image sensing unit 16a may be a charge-coupied device (CCD) sensor or a complementary metal oxide semiconductor JComplementary Metal_〇xide ^, and the sensor control unit π 18 may be Controller with data calculation/processing functions. The memory unit can be flash memory or other non-volatile memory. 201218047 In general, the object is also equipped with soft and hard components necessary for operation, such as the display panel, the central processing unit f 70 (Central Pr〇eessi power supply, (4),, Saki, Depending on the CPU) ' 丨 丨 does not apply.

The optical element 14 is disposed in front of the first light emitting unit 12& In practical applications, the optical element 14 can be a grating, a diffractive element, a micro-projection element, or a combination thereof, whereby the light emitted by the first illumination unit 12a projects the feature pattern 140 via the optical element 14 201218047. In this embodiment, the feature pattern 14A may be a stripe pattern, a dot pattern, a curved pattern, a polygonal pattern, or a combination thereof, depending on the actual application. The feature pattern 丨4 shown in Fig. 2 is exemplified by a stripe pattern. When the object sensing device 1 is used, the control unit 18 first controls the first light emitting unit to emit light. At this time, the 'first-light-emitting unit emits the characteristic pattern 140' via the optical element μ with the emitted light as shown in Fig. 2. When the user indicates the target position ρ on the indication plane 10 by using the object 22 (for example, a finger or a stylus pen), the first issue element projects the feature map through the optical element 14 with the emitted light 14 in the object a. Please refer to FIG. 3 'Fig. 3 is a schematic diagram of the first image η taken by the first image sensing unit. As shown in FIG. 3, the first image η is sensed during the illumination of the first illumination unit i 2 a during the illumination of the first illumination unit i 2 a, wherein the first image η has The feature pattern is 16〇. Next, the control unit ^ is based on the density of the feature pattern 160 in the first image η and the target distance D of the comparison vote 22. For example, if the feature pattern _ ^ in the first shadow _ is set to X, the target distance D of the _ member 22 is 1. It is to be noted that the density of the -6G in the first image η is calculated by the interpolation method using the interpolation method to calculate the target distance d of the object 22. The gate control is as shown in Fig. 3, assuming that the first image sensing unit i6a is t-imaged, the image I of the object 22 falls on the one hundred of the elements, and the feature is projected on the object 22. The image created by the pattern (10)! Including the six stripes falling on the thirty pixels of the -100 pixels, the characteristic pattern 160 of the age of 201218047 comes from Jinma, and the object 22 is first used.

In addition, it should be noted that the same reference numerals are used in the eighth figure (8) and the sixth figure (8), and the principle of operation is substantially the same, and the description is omitted here. Compared with the prior art, the object light-making device of the present invention projects a feature pattern on the object via the optical element, and after the first image sensing unit senses the first image having the characteristic lu pattern, the control unit can be The feature pattern in the first image determines the target distance of the object. In addition, the present invention can calculate the target angle of the object using a conventional positioning algorithm, and then determine the target position indicated by the object on the indication plane according to the target rotation and the target angle. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should fall within the scope of the present invention. 13 201218047 [Simplified Schematic Description] A schematic diagram of an object sensing device according to a first embodiment of the present invention.
