Description

Optics and acceleration co-located mouse and acceleration correcting mode thereof
Technical field:
The present invention relates to a kind of mouse apparatus that is the form of a stroke or a combination of strokes (hereinafter to be referred as pen-shaped mouse) or mouse apparatus (hereinafter to be referred as finger mouse) that contains the finger section fixed sleeve part and their acceleration bearing calibration and method for calculating and locating that adopts the imageing sensor location to combine with the acceleration transducer location.Be specifically related to a kind of like this positioning correction method of mouse apparatus, wherein, micro-control unit is in order to receive optical displacement information, acceleration information etc., utilize optical displacement information to come the sense acceleration and the deviation between mouse actual motion acceleration that becomes the angle with ground level, influenced by acceleration of gravity to cause with corresponding calculation method corrected acceleration sensor, and calculating and export the displacement information of mouse.
Background technology:
In the existing common mouse, because object distance relative fixed when using, the optical imaging device that uses the fixture distance is accurately imaging and location then.The principle of this optical mouse in being called United States Patent (USP) 6233368B1 number of " cmos digital optical navigation chip ", the name of May 15 calendar year 2001 issue is disclosed specially.In this patent, utilize the illuminator that holds in the optical mouse to illuminate directly to be arranged in the workplace of optical mouse below, the imaging system that is contained in the inside makes arbitrary graphic or feature imaging on the photoinduction face of cmos sensor of workplace.Because this mouse directly contacts with workplace when work, the fixed distance of workplace and imaging device, the accurate imaging of imaging len and the location of using the fixture distance.
Because the mouse shape is different with common writing implement shape, it wants whole mouse to operate in being held in the hand, and writes and mapping operation so be difficult to realization.Developed a kind of like this pen-shaped mouse device, when it was carried out accurate mapping operation or writes, it can be realized cursor control accurately and simply write.No. 6151015 (after this claiming " 015 patent ") name of United States Patent (USP) in issue on November 21st, 2000 is called the example that discloses a kind of like this pen-shaped mouse in " the computing machine indicating device of similar pen ".Just as shown in fig. 1, indicating device comprises right cylinder 102, illuminating source 104, lens 110, optics movable sensor 108, switch 106, communication link 116 and 118, button 112 and 114.Illuminating source 104 sends light, and lens 110 make light imaging on optics movable sensor 108 of workplace reflection.So, when optics movable sensor 108 captures the image of workplace of scioptics 110 imagings, can obtain the motion vector of indicating device from the variation of image.
Yet, there is bigger shortcoming in the optical imaging device of " 015 patent " when drawing or write, when the distance of indicating device and workplace changes greatly, because the fixedly depth of field of the optical imaging system of image distance restriction, make the image blur of its workplace on imageing sensor unclear, thereby influence the seizure of sensor, cause location difficulty image.With reference to the input of Fig. 2 to literal " X ", the operation of pen is formed by the start writing action and the combination of actions of starting writing usually.Among Fig. 2, when writing letter " X ", action of writing is made up of following steps: one, step M1: start writing at specified point, write then "/"; Two, step M2: start writing standardized then clockwise circular arc aloft; Three, step M3: start writing at specific point, write " ", start writing then.In whole writing process, starting writing and starting writing all requires mouse to keep accurate localization.Usually in the action of starting writing, look different people's use habit and different with the distance that workplace separates.But in when action of starting writing, because the restriction of the depth of field of lens, it is unclear to be prone to image blur, can not accurately locate.
In order to make mouse in three dimensions, all can realize the location, developed a kind of like this mouse, it inserts acceleration transducer in mouse, detect the space displacement amount of computing mouse by the acceleration to mouse.Be called the example that discloses a kind of like this mouse in " acceleration transducer MousePen " in disclosed Chinese application number 200820026207.6 on September 2nd, 2009 (after this claiming " 076 patent ") name.Just as shown in Figure 3, it comprises an acceleration sensor module, a wireless sending module, a wireless receiving module and a driver module.Owing to utilizing the acceleration location of detecting mouse, need pre-determine the initial motion vector of mouse, but this scheme uses the judgement mouse to use initial vector repose period, is prone to cursor and obviously drifts about in the long-time continuous motion process.
In order to overcome optics and the location difficulty of acceleration optical joint mouse when starting writing, and acceleration transducer mouse initial vector is difficult definite, in use be prone to the obviously problem of drift of cursor, need a kind of like this mouse, it can be installed in pen-shaped mouse or finger mouse smaller volume, and can make mouse when smoothness is write or drawn, starting writing and starting writing all requires mouse to keep than accurate in locating.
Summary of the invention:
Design the present invention is exactly in order to address the above problem.Fundamental purpose of the present invention provides and a kind ofly can be installed in a cover locating device in pen-shaped mouse or the finger mouse and location thereof, calibration steps, it can be installed in pen-shaped mouse or finger mouse smaller volume, and can make pen-shaped mouse when smoothness is write or drawn, starting writing and starting writing all requires mouse to keep accurate in locating.Its foundation: 1, fixedly the optical mouse of image distance can accurately be located under certain object distance; 2, under the known situation of initial motion vector, the acceleration change of applied acceleration sensor mouse changes the variation of calculation of motion vectors smoothly according to detected acceleration, thereby the displacement calculating amount realizes the location.According to above characteristic, adopt built-in imageing sensor of while, acceleration transducer etc. in mouse, utilize the characteristics separately of imageing sensor and acceleration transducer, form and have complementary advantages, realize accurately location.
Set mutual vertical and crossing two of mouse and workplace parallel direction and axially be respectively X-axis, Y-axis.When the setting mouse contacted with workplace, workplace was clear in the imaging of the photoinduction face of imageing sensor through lens combination, and the imageing sensor location is good.
Locate when good when applied image sensor, utilize imageing sensor detect X-axis, the displacement state of Y direction do directly location output.
Because influences such as the change of workplace and mouse distance, the restriction of the mouse lens combination depth of field, workplace material, when applied image sensor is located when bad, need the applied acceleration sensor make acceleration detection, obtaining the acceleration change of mouse, and make location Calculation.
When the acceleration of motion of applied acceleration sensor mouse, because X-axis, the Y-axis of acceleration transducer may become the angle with ground level, be subjected to the influence of acceleration of gravity, the acceleration of the detected X-axis of acceleration transducer, Y direction difference may occur with the acceleration of motion of reality.For reducing this species diversity, need make correction to the detected acceleration of acceleration transducer to the mouse location influence.
The method of the accekeration that the corrected acceleration sensor gets is: locate when good at applied image sensor, utilize imageing sensor to detect the displacement information of mouse in X-axis, Y direction, according to the acceleration of motion value of the detected displacement information computing mouse of imageing sensor, promptly obtain the actual acceleration of mouse in X-axis, Y direction; On X-axis, Y direction, detect acceleration transducer to such an extent that the actual acceleration that obtains of acceleration and imageing sensor detection computations is made comparisons respectively, calculate their difference, be mouse acceleration calibration value on X-axis, Y direction; The method of the accekeration that the corrected acceleration sensor gets is: before applied acceleration sensor location, use above-mentioned method and calculate the acceleration corrected value.When the applied acceleration sensor was done the location, the accekeration applied acceleration corrected value of the detected X-axis of acceleration transducer, Y direction was proofreaied and correct, and can obtain the actual acceleration value.
When applied image sensor is located when bad, calculate the displacement of respective cycle (being set at the n cycle), can be according to before the applied acceleration sensor location, the actual acceleration value in the 1st to n cycle after the X-axis of utilizing imageing sensor to locate to detect when good, the motion vector of Y direction, cycle length, the correction, but the X-axis in the n cycle of computing application acceleration transducer location, the displacement of Y direction, and output result.
As seen, when mouse and workplace when changing, no matter whether the optical alignment of mouse good, mouse still can be realized than accurate in locating.
By as seen above-mentioned, in positioning process, need correctly to judge whether the imageing sensor location is good.Judge whether method well commonly used has in the imageing sensor location: 1, setting pressure sensor on pen-shaped mouse or finger mouse, be used to detect whether contacting of mouse and workplace, when the setting mouse contacts with workplace, workplace is positioned at the field depth of the optical lens group of mouse, therefore, when the mouse front end contacted with workplace, the imageing sensor of decidable mouse location was good.2, utilize the detected image definition of imageing sensor to judge the location situation of the imageing sensor of mouse; Usually, when workplace scioptics group when imageing sensor photoinduction surface imaging is good, the detected image of imageing sensor is more clear, image processor can be judged the image quality of image, and judge in view of the above whether imageing sensor location is good, and whether the output image sensor locatees good information.Above dual mode can be used simultaneously, complements one another, and is beneficial to correct judgement.
When mouse is write or is drawn, also need to take a decision as to whether pen-down state, judging whether has for pen-down state method commonly used: 1, setting pressure sensor on pen-shaped mouse or finger mouse is used to detect whether contacting of mouse and workplace, to judge whether being pen-down state; Further, utilize pressure transducer to understand the power of the contact pressure of mouse and workplace, can also control the size of person's handwriting, strengthen writing and painting effect.2, judge the location situation of the imageing sensor of mouse according to the detected image of imageing sensor, when imageing sensor is located when good, workplace is positioned at the field depth of lens combination, usually effective depth of field of mouse lens combination is less, and when setting mouse and contacting with workplace, workplace is positioned at the field depth of lens combination, therefore, can set imageing sensor photoinduction surface imaging when good, mouse contacts with workplace, and promptly mouse is a pen-down state.3, the acceleration transducer of mouse is used three acceleration transducer, setting on the mouse axle vertical and crossing with X-axis, Y-axis is the Z axle, good in mouse images sensor location, and the mouse applications imageing sensor is positioned in prescribed motion time or the distance, acceleration transducer on the Z axle, detect vector acceleration when constant substantially, definition mouse and workplace are contact condition, and promptly mouse is a pen-down state.
The remarkable advantage of foregoing invention is: when having angle change in the use of pen-shaped mouse and finger mouse, utilize the characteristic separately of optical alignment and acceleration location, can to detecting of acceleration transducer acceleration make calibration, mouse all can made than correct positioning under the workplace different distance.

R is a constant, is used for adjusting in calculating the relation of displacement information and acceleration information; It can be according to the sensitivity (s of mouse optical detection l), the sensitivity (s of acceleration transducer a), the detection error of cycle length (t), device etc. makes adjustment.Here set: r ≈ (s a/ s l) * t^2; Usually, the r value is made adjustment according to above-mentioned parameter when production and is set.
Illustrate: when positioning, the location of mouse need be located in two kinds of different judgements and the computation schema with the applied optics sensor in the applied image sensor location and be switched.In following calculating is described, when after acceleration variable or offset variable, adding corresponding subscript as sequence number (as: 1,2,3 ..., n-1, n etc.), this subscript value represents that the variable of correspondingly subsidiary cycle numbering then is meant the variate-value in corresponding cycle from entering the numbering of the respective cycle after this calculating and the judgment model.
When k=1 (promptly adopt imageing sensor location good), utilize imageing sensor directly to locate, and the displacement of output X-axis, Y-axis.
The computing method of acceleration corrected value:
Utilize the X-axis that the detected displacement state of imageing sensor calculates, acceleration (Alx, the Aly of Y direction; Unit: mm/s^2):
Alx＝(l xn-l x(n-1))*s l/t^2
Aly＝(l yn-l y(n-1))*s l/t^2
Utilize actual acceleration (Aax, the Aay of the detected acceleration of acceleration transducer after calibration; Unit: mm/s^2):
Aax＝(a xn+a xΔ)*s a
Aay＝(a yn+a yΔ)*s a
When k=1 (be imageing sensor location good), on X-axis and Y direction, utilize imageing sensor detect the accekeration that calculates of displacement information (Alx, Aly) with utilize acceleration transducer detect accekeration through the actual acceleration value (Aax of calibration, Aay) equate, then have:
Alx＝Aax
Aly＝Aay
Then have:
(l xn-l x(n-1))*s l/t^2＝(a xn+a xΔ)*s a
(l yn-l y(n-1))*s l/t^2＝(a yn+a yΔ)*s a
Can calculate thus the corrected value (a of acceleration The x Δ, a The y Δ) (unit: LSB)
a xΔ＝(l xn-l x(n-1))*(s l/s a)/t^2-a xn
a yΔ＝(l yn-l y(n-1))*(s l/s a)/t^2-a yn
Because r ≈ (s a/ s l) * t^2, so the corrected value (a of acceleration The x Δ, a The y Δ) (unit: LSB) be:
a xΔ≈(l xn-l x(n-1))/r-a xn
a yΔ≈(l yn-l y(n-1))/r-a yn
When k=0, can use the actual acceleration value (Ax in the corresponding cycle (n cycle) that above-mentioned acceleration correction value must be in this calculating and judgment model n, Ay n) (unit: LSB)
Ax n＝a xn+a xΔ
Ay n＝a yn+a yΔ
Utilize the computing method of acceleration transducer location:
When k=0, according to the last effectively displacement (l in optical alignment cycle X0), the acceleration accumulative total variable quantity in the 1st to (n-1) cycle of applied acceleration sensor location
