Abstract

The utility model relates to a digital telescope, comprising an optical telescope, a digital camera, and a notebook PC, wherein, the optical telescope is connected with the digital camera, and the digital camera is connected with a computer which is provided with an acquisition and processing module of monitoring image through a USB interface, and the optical telescope and the digital camera are fixedly connected through a sleeve, and the optical telescope is a pocket telescope of 12 x 25 specification with focusing function, wherein, the diameter of an eyepiece tube is 30 mm; and the digital camera is a CMOS digital camera with 300,000 pixels. Compared with the digital camera telescope in the current market, the digital telescope has obvious price advantage; and the image can be directly stored in computer hard disk, which is suitable for requirements of long-time remote monitoring.

Description

Digital telescope

Technical field

The utility model relates to a kind of digital photographing telescope, especially a kind ofly repacks the ordinary optical telescope into digital telescope, makes it to have video acquisition, the digital photographing telescope of storage and image processing function.

Background technology

Digital telescope can become the image taking in the visual field digital photograph and preserve, and in fields such as residential quarter safety monitorings important use is arranged.Popular in the market digital telescope adopts FPGA more, the contour process chip frequently of looking closely of DSP, and wiring board is made numerous and diverse, costs an arm and a leg.Having limited it applies.For this reason, need a kind ofly repack the ordinary optical telescope into simple and easy digital telescope.

Summary of the invention

The utility model is that a kind of digital telescope will be provided, and it is low that this telescope has price; And image can directly be stored on the hard disc of computer, is fit to the characteristics such as needs of long-time remote monitoring.

For achieving the above object, the technical solution of the utility model is: a kind of digital telescope, comprise optical telescope, be characterized in: also comprise digital camera head, notebook computer, wherein, optical telescope is connected with digital camera head, and digital camera head is connected with the computer of processing module with the collection with surveillance map picture.

Digital camera head is connected with computer by USB interface.Fixedly connected by sleeve between optical telescope and the digital camera head.

Optical telescope is the pocket telescope of 12 * 25 specifications with focusing function, and wherein, the eyepiece stalk diameter is 30mm.

Digital camera head is the CMOS digital camera head of 300,000 pixels.

The beneficial effects of the utility model are:

The utility model is to finish the collection and the processing of video image by being installed in software on the PC, and cost is about equal pixel digital telescopical 1/8.As long as the user has a Daepori logical home PC or notebook computer, can utilize this device to realize taking pictures and handling of distant place object.Three parts of the utility model device: the ordinary optical telescope of 12 * 25 specifications that (1) can buy on the electronic market, about 100 yuan of prices.(2) digital camera head of CMOS640 * 480 (300,000 pixel), about 100 yuan of prices.Home PC that has USB interface or notebook computer that (3) one Daeporis are logical.Therefore, the utility model is compared with digital photographing telescope in the market, has tangible price advantage; And image can directly be stored on the hard disc of computer, is fit to the needs of long-time remote monitoring.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, digital telescope of the present utility model comprises optical telescope 1, digital camera head 2, computer 3, the collection of surveillance map picture and processing module.

Optical telescope 1 is connected with digital camera head 2, and digital camera head 2 is connected with the computer 3 of processing module with the collection with surveillance map picture.And digital camera head 2 is connected with computer 3 by USB interface.

Embodiment of the present utility model is:

1. optical telescope 1 and digital camera head 2 is connected

In this example, adopt 12 * 25 pocket telescopes.It has the focusing function, eyepiece stalk diameter 30mm.Adopt the CMOS digital camera head of 640 * 480 (300,000) pixel.The cartridge type encapsulation is selected in both connections for convenience, digital camera head for use, and external diameter 28mm is slightly less than telescope ocular diameter 30mm.If both diameters differ bigger, can adopt plastic sleeve to be connected and fixed.

In addition, in use optical telescope 1 and the digital camera head 2 that connects to be fixed on the A-frame 4, prevent flating.And, obtain monitoring picture clearly by the focusing knob that optical telescope 1 carries.

2.. digital camera head 2 is connected with computer 3

In this example, in order to reduce cost, digital camera head 2 adopts general CMOS640 * 480 types in low side field to carry the digital camera head of driving.Be connected with PC or notebook computer 3 by USB interface, the user does not need install driver, has the plug-and-play feature of peripherals such as similar mouse.

In the above operating system of WindowXP, if successful connection, the control panel that the user opens computing machine it will be appreciated that one and is labeled as the icon of " USB video equipment ".Double-click this icon and can see video image in the telescope visual field.If image is clear inadequately, can reconcile telescopical focusing knob.Be noted that in addition to make telescope directly aim at the sun, in order to avoid damage digital camera head.

3. the collection of surveillance map picture and processing module.

The user can watch surveillance map picture in the telescope visual field by the program that the WindowXP system carries, but is difficult to directly video be preserved, and perhaps sensitization picture is done further processing.For realizing the collection and the storage of surveillance map picture, any method in the following two kinds of methods of the optional usefulness of user:

(1) according to shown in Figure 1 will install correct the connection after, the user installs Flame Image Process business softwares such as PhotoShop voluntarily.Open by PhotoShop " file "-" " image input " menu, select " Twain: selection equipment ... " option (note: Twain is a kind of underlying protocol of video equipment and compunication), in ejecting dialog box selected " WIA-USB video equipment ", can set up being connected between digital telescope and the PhotoShop.

(2) method in (1) is simple, but may relate to the copyright problem of software, and can't preserve row to video.For this reason, utilize the free OpenCV that increases income to develop digital telescope monitoring image acquisition and processing specific program, can provide free to the user.The monitoring video can avi file form preserve and playback; In observation process, press the file that the Esc key can save as sensitive image jpg compressed format.
