Abstract
The invention discloses a method applied to calibration of touch screens of embedded devices. Three calibration points are arranged on a touch screen; coordinates of the three calibration points are respectively recorded; three corresponding points are correspondingly arranged on a display screen; a corresponding relation is built by carrying out proportional conversion between coordinates of three corresponding points recorded by an application program of a pattern user interface and the coordinates of the three calibration points in bottom drive of the touch screen, so that calibration judgment is implemented; the calibrated information is recorded and saved in a configuration file; the corresponding information is read when the device is started in the next time. By virtue of the method, touch screens of embedded DVR, NVR and hybrid DVR devices with resistive touch screens are calibrated by clicking by virtue of touch pens; the accuracy of clicking the pattern user interfaces of the devices by users is improved; the user experience of the devices is improved; the method is convenient to operate.
Description
Technical field
The invention belongs to field of video monitoring, be specifically related to a kind of touch screen correction method and equipment thereof of embedded device.
Background technology
Embedded digital video recorder (DVR) (Digital Video Recorder and DVR) equipment is that one can connecting analog video camera, ball machine etc., and its vision signal of analog acquisition, carry out this locality and export echo, and the embedded type network video equipment that Video coding this locality stores, network real-time video is propagated.
Embedded NVR(Network Video Recorder and network hard disk video recorder) equipment is that one can connect and control IPC (Internet Protocol Camra and web camera) front end, the video data transmitted by IPC carries out this locality and stores and forwarded, and decoding is on the output interface of NVR equipment, and show the equipment of the real time video signals that IPC gathers.
Embedded mixed type DVR equipment is the built-in hard disk video tape recorder equipment of embedded digital video recorder (DVR) and the set of NVR functions of the equipments.
Due to embedded digital video recorder (DVR), NVR, mixed type DVR equipment considers the factors such as cost, use resistive touch screen, on equipment, the output LCD display of touch-screen and its behind is separately assembling, there is certain error, and owing to patching the existence of resistance, cause circuit parameter not too consistent, therefore touch-screen will correct before use, graphic user interface (GUI can be converted to by correcting the raw data obtained, Graphical User Interface) on software coordinate, thus be convenient to utilize touch screen operation embedded digital video recorder (DVR) accurately, NVR, the graphic user interface of mixing DVR.
With on the embedded digital video recorder (DVR) of touch-screen, NVR, mixed type DVR equipment; user is operated by the graphic user interface of felt pen to equipment; but due to the reason of touch-screen; often there will be can accurately the situation of corresponding control in click graphical user interface, makes troubles to the operation of user.Process provides.
Summary of the invention
The present invention is to solve touch-screen click coordinate and lcd screen displaing coordinate is inconsistent problem below, and the one proposed is corrected touch-screen input by triplet, and the error of coordinate that causes of reason can be installed correct touch-screen itself, facilitate user by the touch screen correction method of the embedded device of graphic user interface exact operations and equipment thereof.
Technical scheme of the present invention is:
A kind of touch screen correction method of embedded device, described touch-screen is provided with three calibration points, record the coordinate of three calibration points respectively, on display screen, correspondence is provided with three corresponding point, by the coordinate of three corresponding point of the application records of graphic user interface, and carry out ratiometric conversion with the coordinate of three calibration points in touch-screen bottom layer driving, set up its corresponding relation, thus carry out calibration judgement, information record after calibration is saved to configuration file, when equipment startup next time, reads corresponding information.
The invention has the beneficial effects as follows:
The invention solves embedded digital video recorder (DVR), NVR, the mixed type DVR equipment with resistive touch screen, clicked by felt pen and carry out touch screen correction, improve the accuracy of user's pointing device graphic user interface, lifting means Consumer's Experience, handled easily.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention;
Fig. 2 is structural representation of the present invention.
Embodiment
Below, with reference to drawings and Examples, the present invention is described in detail:
As shown in Figure 1, the touch screen correction method of embedded device of the present invention, described touch-screen is provided with three calibration points, record the coordinate of three calibration points respectively, on display screen, correspondence is provided with three corresponding point, by the coordinate of three corresponding point of the application records of graphic user interface, and carry out ratiometric conversion with the coordinate of three calibration points in touch-screen bottom layer driving, set up its corresponding relation, thus carry out calibration judgement, information record after calibration is saved to configuration file, when equipment startup next time, reads corresponding information.
The touch screen correction method of embedded device of the present invention, concrete calibration steps is as follows:
I user starts touch screen calibration, touch-screen enters calibration mode, judge whether to preserve calibration result, if preserved calibration result, user click event, according to calibration mode process, directly carries out process user click event, judges whether user's click location and time meet, if the calibration result of preservation, registration touch screen calibration tasks;
After II registration touch screen calibration tasks, judge that whether the untreated time is more than 3 minutes, if exceed, exits calibration mode, terminate touch screen calibration, if do not exceed, draw box and hint prompting at interface, prompting user please touch by screen upper flicker square frame center until progress bar full after unclamp;
After III user's point touching screen, carry out process user click event, judge whether user's click location and time meet, if do not meet, re-start user's point touching screen, if meet, then judge whether to reach maximum calibration point;
IV when not arriving maximum calibration point, enters next calibration point, and re-start user's point touching screen;
V when arriving maximum calibration point, and prompting is ejected at interface, determines whether to preserve calibration result, preserves, then, after preserving calibration result, exit calibration mode if determine, terminates touch screen calibration, if do not preserve, then directly exit calibration mode, terminates touch screen calibration.
As shown in Figure 2, the touch-screen calibration equipment of embedded device of the present invention, comprises embedded device, also comprises embedded device and is provided with video output, video output is connected with LCD display, and LCD display is also provided with the touch-screen be connected with embedded device.
The invention solves embedded digital video recorder (DVR), NVR, the mixed type DVR equipment with resistive touch screen, clicked by felt pen and carry out touch screen correction, improve the accuracy of user's pointing device graphic user interface, lifting means Consumer's Experience, handled easily.
