Using several specific embodiments, the technical schemes of the invention are described in detail below.
Embodiment one
Fig. 1 is the detection method schematic diagram that the embodiment of the present invention shows equipment, as shown in Figure 1, the display of the present embodiment is set Standby detection method, display equipment includes signal source interface, and the detection method of the display equipment includes image detection and sound Detection.
For example, in the present embodiment, display equipment (such as television set, computer display screen or advertisement screen etc.) to be detected Equipped with multiple signal source interfaces, multi-signal can receive with compatibility, for example, ATV (Analog TV, input simulation) signal, AV (audio A udio and video Video) signal, DP (DisplayPort, high-definition digital display port) signal, DTMB (Digital Television Terrestrial Multimedia Broadcasting, digital TV ground multimedia broadcasting) signal, DVI (Digital Visual Interface, digital visual interface) signal, HDMI (High Definition Multimedia Interface, high-definition multimedia interface) signal, MHL (Mobile High-Definition Link, Mobile terminal high-definition audio and video standard) signal, VGA (Video Graphics Array, Video Graphics Array) signal or YPrPb At least one of (color difference components simulation) signal.
Image detection the following steps are included:
Step S101: the image of image acquisition device being displayed on the screen, the image being displayed on the screen are obtained It is generated based on image sensing signal;Image sensing signal is generated based on standard picture.
For example, in the present embodiment, by all channels to be detected of display equipment to be detected (i.e. signal source interface) It is connect with signal source generating device and (artificial plug wire mode can be used, robot automatic wire inserting mode can also be used, all examined when all , similarly can be using manually pulling out line mode after having surveyed, or line mode is pulled out using robot automatically) after, by infrared remote control or Cable communication will show that equipment is transferred under the corresponding modes for needing the signal path detected, and detection device gives signal source generating device Send instructions, so that signal source generating device is issued corresponding detection signal to display equipment to be detected, it is made to show that image, image are adopted The image of acquisition means acquisition display, and so on, then will show that equipment is transferred to the corresponding of next signal path for needing to detect Under mode ..., for example, carry out ATV signal and HDMI signal Image Acquisition, will show equipment on ATV signal source interface and HDMI signal source interface is connect with signal source generating device, and display equipment is transferred to ATV mould by infrared remote control or cable communication Under formula, detection device sends instructions to signal source generating device, so that signal source generating device is issued ATV detection signal, shows equipment Show image, the image of the image acquisition device display;The Image Acquisition for carrying out next signal will show equipment tune To under HDMI mode, detection device sends instructions to signal source generating device, and signal source generating device is made to issue HDMI detection signal, Display equipment shows image, the image of the image acquisition device display.And so on, if display equipment can also receive Other signals need to carry out coherent detection, successively acquire its corresponding image for being shown in display equipment.
In the present embodiment, the detection signal that signal source generating device is sent is (for example, image sensing signal or video inspection Survey signal etc.) it is a kind of standard drawing, which is that client is selected according to their own needs, and main purpose is to detect Signal whether can be received and show corresponding picture, in the case that display equipment does not receive any signal, equally may be used It is displayed in red with autonomous, white, black, blue, green, even the pure color field of other colors, that cannot select these Pure color picture is the standard drawing of image sensing signal, so can choose tool to detect the color contrast etc. of display equipment Obvious contrast simultaneous selection is not the standard drawing for the pure color for showing that equipment autonomously is shown, such as colour pattern, colour pattern color lump In can be used as the standard of detection with many kinds of parameters, such as the quantity of colour bar, the length of transitional region, width, face in colour pattern The parameter of product, gradient and homogeneity can be used as the reference of detection;Or shade of gray figure etc. these and display equipment itself The picture that cannot be shown.
Step S102: analysis image collecting device acquired image, to obtain display testing result.That is, inspection It surveys device the acquisition image and standard drawing that receive are compared, according to the difference of acquisition image and standard drawing parameters Whether the different display function for judging display equipment to be detected is normal.
The step is specifically further divided into following steps, comprising:
Step S1021: from image acquisition device to image in isolate display equipment screen area image.
For example, detection device will determine the detection range of the acquisition image received.Such as general light emitting region is The screen area for showing equipment, this partial region is cut out as detection range.It can also be according to image collecting device Placement location and acquisition range determine the screen area in image, intercept out the figure in acquired image in preset range with this As region is as detection range.
Step S1022: quantity, length, width, area, the gradient of the transitional region of color lump in screen area image are calculated With at least one of homogeneity parameter.For example, when the detection signal that signal source generating device is sent is colour pattern, due to colour bar Figure boundary is than more visible, and similar to the transition of tomography formula, transitional region should be an apparent straight line, be held by algorithm comparison Easily divide region, find color lump by calculating the gray scale of picture in the algorithm, and by its quantity of gray count, length, Width, area, gradient and homogeneity etc. parameter are to be compared.
Step S1023: compare the relevant parameter for calculating resulting parameter and standard picture, to obtain display testing result.
For example, if standard drawing is using colour pattern, each parameter of standard drawing be it is known, by colour pattern The parameter that colour bar quantity is analysed and compared as one, if the colour bar quantity of image is less than the colour bar number of standard drawing in detection range Amount, then testing result is to lack color anomaly, if the colour bar quantity of image is more than the colour bar quantity of standard drawing in detection range, is examined Surveying result is that figure interference is abnormal, if the colour bar quantity of image and the colour bar quantity of standard drawing are identical in detection range, is detected As a result normal for the detection of colour bar quantity, next step detection is carried out, that is, successively calculate and analyze length of transition zone, width, Gradient, whether homogeneity is identical with the colour pattern of standard drawing, identical then normal, not identical then abnormal for figure interference.
It should be noted that the partial parameters of standard drawing are the display effect for influencing display equipment, display is had no effect on The display function of equipment, so testing result can be divided into two parts, it is normal that one is display functions, such as testing result is Display detection is qualified, and display function is abnormal, such as testing result is that display detection is unqualified;Another kind is display effect etc. Grade, such as the range judgement testing result compared according to parameter is 1 grade of display effect, 2 grades of display effect, 3 grades of display effect, with Corresponding different display effect.
Sound detection the following steps are included:
Step S201: the audio of the display equipment output of audio collecting device acquisition, the audio of display equipment output are obtained It is generated based on audio detection signal.
For example, in the present embodiment, it is also possible to which all channels to be detected of display equipment to be detected (are believed Number source interface) connect with signal source generating device after, display equipment is transferred to by infrared remote control or cable communication and needs to detect Signal path corresponding modes under, detection device sends instructions to signal source generating device, make signal source generating device issue phase Corresponding detection signal makes it play audio, audio collecting device acquires the audio played, successively class to display equipment to be detected It pushes away, then will show that equipment is transferred under the corresponding modes of next signal path for needing to detect ..., for example, carrying out ATV signal With the audio collection of HDMI signal, it will show that the ATV signal source interface in equipment and HDMI signal source interface and signal source occur Display equipment is transferred under ATV mode by device connection by infrared remote control or cable communication, and detection device is filled to signal source It sets and sends instructions, signal source generating device is made to issue ATV detection signal, show device plays audio, audio collecting device acquisition should The audio of broadcasting;Display equipment is transferred under HDMI mode by the audio collection for carrying out next signal, and detection device is to signal source Generating device sends instructions, and so that signal source generating device is issued HDMI detection signal, shows device plays audio, audio collecting device Acquire the audio of the broadcasting.And so on, if display equipment can also receive other signals and need to carry out coherent detection, successively Acquire its corresponding broadcasting audio.
It in the present embodiment, include audio detection signal, audio detection in the detection signal that signal source generating device is sent Signal includes the binaural audio signal of same phase different frequencies, with out of phase binaural audio signal frequently and with frequently with mutually but frequently At least one of the binaural audio signal of rate variation.For example, the binaural audio signal with phase different frequencies can be left sound Road frequency is 400Hz, right channel frequency is 1000Hz, the identical audio signal of left and right acoustic channels phase;With the out of phase alliteration of frequency It is 1000Hz, the audio signal that phase difference is 180 degree that audio channel signal, which can be left and right acoustic channels frequency,;With frequency with phase but frequency The two-channel swept-frequency signal of variation can be the swept-frequency signal that left and right acoustic channels parameter is all the same but frequency is from 20Hz to 2000Hz.It can Go out acoustic problem to have individual audio detection signal detections according to these, it may for example comprise it is noiseless, reversed, sound is light, sound it is disconnected with And sound vibration etc., and the problem of detected according to these, accurately find the root of generation problem.In practical application, The audio detection signal that signal source generating device is sent can be the continuous audio signal of three section audio signals composition, and first segment is L channel frequency 400Hz, right channel frequency 1000Hz other parameters voice signal all the same, second segment are left and right acoustic channels frequency It is 1000Hz, the voice signal that phase difference is 180 degree, other parameters are all the same, third section is that left and right acoustic channels parameter is all the same But swept-frequency signal of the frequency from 20Hz to 2000Hz.
Step S202: analyzing the collected audio of the audio collecting device, to obtain sound detection result.Namely It says, detection device analyzes the i.e. two groups of audios in left and right of the acquisition audio received, two groups of audios are depicted as audio graphics, Relevant detection and analysis are carried out, can specifically include noiseless detection and analysis, the analysis of left and right acoustic channels inverse detection, left and right acoustic channels phase Difference is analysed, sound gently tests and analyzes, tone level tests and analyzes, sound breaks at least one of detection and analysis and sound vibration detection and analysis.
