Abstract
The invention discloses a magnification measurement method for a handheld electronic terminal with an imagery function. The method includes: when length or angle measurement needs to be performed, an image of the handheld electronic terminal with the imagery function is obtained; and through superposition scale and protractor functions on the image, measurement of the length and the angle is more convenient. In the magnification measurement method for the handheld electronic terminal with the imagery function, a new function is added to the handheld electronic terminal with the imagery function: the terminal has a length and angle measurement function so that convenience is provided to users.
Description
Technical field
The present invention relates to handheld electronic field, in particular a kind of image measurement by magnification function of the hand held electronic terminals based on camera function.
Background technology
In daily life; length, angle and amplification that people often can need to measure wisp show; as Electronics Engineer often can need the welding situation of lens examination components and parts, the package dimension of tolerance device, and magnifier, ruler amount and protractor generally can not be carried.
Along with popularizing of hand held electronic terminals especially mobile phone, become indispensable instrument in people's life, but existing hand held electronic terminals do not have this function.
Therefore prior art haves much room for improvement.
Summary of the invention
The technical problem to be solved in the present invention is, by software engineering, is supporting in the hand held electronic terminals of camera function, and the amplification that realizes observed objects shows, measures the length of captured object, the function of angle, is one simple and easy measurement facility easily.At ken central point, the accuracy of measurement of length is 0.1mm, and the precision of angle is 1 °, has met the tolerance demand that requires degree not high.The present invention does not increase hardware cost, solves by software engineering the demand that simple and easy tolerance length and angle and amplification show, has good economic benefit and social benefit.
The technical scheme that technical solution problem of the present invention adopts is as follows;
The amplification tolerance implementation method of the hand held electronic terminals with camera function, wherein, comprises step:
The camera of the hand held electronic terminals of A, rotating band camera function, by the digital imaging technology of testee on the screen of hand held electronic terminals;
B, the user control interface that superposes on the upper strata of testee image, control interface display linear measure longimetry rule, protractor, scaling adjustment bar, survey instrument selection, light filling switch;
C, by controlling interface, user can State selective measurements instrument be linear measure longimetry or measurement of angle, after State selective measurements instrument, regulates scaling adjustment bar to be adjusted to suitable scaling ratio and carries out reading.
The amplification degree metering method of the described hand held electronic terminals with camera function, wherein, described step C also comprises step:
C1, linear measure longimetry calibration mode, due to the ratio difference of amplifying, need to calibrate the scale of linear measure longimetry scale.The method of calibration is that minimum scale of selection is the ruler of the clear scales of millimeter, ruler is taken in to ken central authorities, control the scaling ratio of the rule on interface by adjusting, allow the millimeter scale of the millimeter scale of its rule and the ruler of absorption coincide, calibrated.
C2, linear measure longimetry pattern are selected linear measure longimetry pattern on control interface, and testee is taken in to ken central authorities, after image boundary is clear, can pass through rule reading.
C3, measurement of angle pattern, controlling selected angle measurement pattern on interface, take in ken central authorities by testee, after image boundary is clear, and can reading.
C4, light filling function, in the time of insufficient light, if can carry out light filling by the flashlamp of light filling switch open hand held electronic terminals, thereby see testee clearly.
Accompanying drawing explanation
Accompanying drawing is the processing flow chart that the software of the amplification degree metering method of the hand held electronic terminals with camera function is realized
Embodiment
For making object of the present invention, technical scheme and advantage clearer, clear and definite, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Please refer to accompanying drawing, accompanying drawing is the process flow diagram that the present invention is based on the preferred embodiment of the amplification degree metering method of the hand held electronic terminals with camera function, and the amplification degree metering method of the described hand held electronic terminals based on camera function comprises the following steps:
Step S110, enters and loads interface after startup software, now drives the camera head of target device;
Step S120, enters measurement by magnification interface, and this interface is divided into two-layer demonstration, and lower floor is the image of taking in from camera, and upper strata is to control interface;
Step S130, after system starts, acquiescence enters linear measure longimetry pattern, under this pattern, carry out the linear measure longimetry work of object, method is that camera is aimed to testee, the image of testee is taken in to ken central authorities, synchronously amplify by amplifying scale, treating can reading when user feels sharply marginated.The checking the calibration pattern that can also be switched to linear measure longimetry under this pattern is S150, also can be switched to measurement of angle Mode S 140;
Step S140, takes in ken central authorities by testee, synchronously amplifies by amplifying scale, chooses tested angle, treats when user feels sharply marginated to carry out reading.Under this pattern, can also be switched to linear measure longimetry Mode S 130.
Step S150, selecting a minimum scale is the ruler of the clear scales of millimeter, and ruler is taken in to ken central authorities, controls the scaling ratio of the rule on interface by adjusting, allow the millimeter scale of the millimeter scale of its rule and the ruler of absorption coincide, calibrated.Complete after calibration, can carry out linear measure longimetry work.
Claims (4)
1. the camera of the hand held electronic terminals of rotating band camera function, by length and measurement of angle scale and the user interface image upper strata that camera takes in that is added to.
2. support to amplify metric function, by the scaling regulatory function of user interface, synchronously zoom in or out scale and testee image.
3. while measurement, can open the light filling function of the hand held electronic terminals with camera function.
