Further, first object laser range sensor can be according to preset trigger position and preset laser Transition matrix between ranging mould group and camera module determines.It is above-mentioned i.e. in a kind of possible way of realization of the embodiment of the present application Before step 101, can also include:

According to the transition matrix between preset laser ranging module and camera module, determine in the laser ranging module, First object laser range sensor corresponding with trigger position preset in the camera module.

It should be noted that the transition matrix between laser ranging module and camera module, can be laser ranging module and sets After meter, production and calibration are completed, i.e., after the position of each laser range sensor determines in laser ranging module, pass through test Determining.

As a kind of possible implementation, each laser range sensor pair in laser ranging module can be controlled first Tested region carries out laser scanning, obtains the point cloud data of laser ranging module, and it is anti-according to tested region to control camera module The laser signal penetrated obtains the framing image data of tested region, and then is sensed according to laser ranging each in laser ranging module Position of the corresponding laser spot of device in the framing image data of camera module, progress coordinates computed conversion parameter, and according to The coordinate transformation parameter projects the point cloud data of laser ranging module into the framing image data of camera module, to be swashed Transition matrix between ligh-ranging mould group and camera module.

It should be noted that tested region is that laser ranging module carries out a default size caused by laser scanning The maximum frame region of the square area or laser ranging module scanning field of view of rectangular area or default size.It is right Tested region carries out laser scanning, including following scan method: method, the method for line scanning, square scanning side of spot scan Method etc..Wherein, spot scan method refers to four points of scanning every time, is scanned from the outermost of screen to the centre of screen；Line The method of scanning refers to one horizontal line of scanning or a vertical line every time, from the another side of screen scanned on one side to screen；Just Rectangular scan method refers to the square that one four edges frame of scanning surrounds every time, first scans in screen outermost maximum square The size of square is gradually reduced in shape, until smallest square of the scanning to the centre of screen, or until screen is arrived in scanning An intermediate point.

Optionally, in the calibration of camera module and laser ranging module, the laser that camera module is used to capture transmitting shines Bright position, for Calibration of Laser ranging mould group, using scannings sides such as above-described spot scan, line scanning, square scannings Formula realizes system calibrating.Before calibration, laser ranging module scanning can produce a fixed figure, for example rectangle or Other fix figure, this figure can be the maximum frame of laser ranging module scanning field of view.Existed by observing laser spot Position on camera module image, adjustment laser ranging module accurately emits visual field frame, to obtain laser ranging module The transition matrix between camera module.For example, transition matrix can be following form between laser ranging module and camera module:

{0 0 0 1 0 0 2 0 3 0 0 4

……

}

Wherein, every a line in transition matrix represents the pixel of a line in camera module image.0 represents camera module figure The pixel as in does not have laser point to fall into, and 1 represents the corresponding laser point of first laser range sensor, and 2 represent second The corresponding laser point of a laser range sensor, and so on.In laser ranging module real time execution, laser pickoff will be adopted The parameter informations such as the distance of reference object, time, light intensity are put into transition matrix in the shooting picture collected, are formed and camera shooting mould The point cloud data for the laser ranging module that group has merged.

It is understood that can directly according to preset trigger position and be preset in known preset trigger position Laser ranging module and camera module between transition matrix, determine preset trigger position corresponding member in transition matrix Element, so according to preset trigger position in transition matrix corresponding element, determine preset trigger position corresponding One target laser distance measuring sensor.

Further, preset trigger position can be the default parameters in corresponding screening-mode, be also possible to user According to actual photographed demand, input in real time.I.e. in a kind of possible way of realization of the embodiment of the present application, above-mentioned steps 101 Before, can also include:

Obtain the preset trigger position that user inputs at image preview interface.

As a kind of possible implementation, user can be allowed according to shooting demand, led to before video capture starts The input unit (touch screen, mouse, keyboard etc.) for crossing electronic equipment, inputs preset trigger position in image preview interface, To meet the individual demand of user, and improve usability.Therefore, it can be inputted in image preview interface with real-time detection user Instruction, and when detecting user in image preview interface and inputting the instruction of default trigger position, the finger that is inputted from user In order, the preset trigger position that user inputs in image preview interface is obtained.

As a kind of possible implementation, preset trigger position can also be preset, i.e., by preset triggering Acquisition parameters of the position as corresponding screening-mode are preset in the electronic device.For example, the camera module of electronic equipment has slowly Action video shooting function, then can be in slow motion screening-mode, using preset trigger position as slow motion screening-mode Acquisition parameters, i.e. user, can be directly from the acquisition parameters of slow motion screening-mode after selecting slow motion screening-mode In, get preset trigger position.

Step 102, judge what the first object laser range sensor exported respectively at current time and previous moment Whether the difference of distance value is greater than preset value, if so, executing step 103；Otherwise, 101 are returned to step.

Step 103, the camera module is adjusted by the first shooting frame rate to the second shooting frame rate.

It in the embodiment of the present application, can be according to first object laser range sensor at current time and previous moment point The distance value not exported, determines whether reference object current time reaches the corresponding ranging of first object laser range sensor Point.Specifically, may determine that the distance value that first object laser range sensor exports respectively at current time and previous moment Difference whether be greater than preset value, if more than preset value, then can determine that reference object reaches first object at current time The corresponding point distance measurement of laser range sensor, i.e. reference object reach preset trigger position at current time, then can incite somebody to action The shooting frame rate of camera module is adjusted by the first shooting frame rate to the second shooting frame rate；If first object laser range sensor exists The difference for the distance value that current time and previous moment export respectively can then determine reference object current no more than preset value Moment does not reach the corresponding point distance measurement of first object laser range sensor, i.e. reference object does not reach preset at current time Trigger position then without being adjusted the shooting frame rate of camera module, and continues to obtain first object laser range sensor In the distance value that subsequent time and current time export respectively, whether reached with to judge reference object in subsequent time preset Trigger position.

It should be noted that if the distance value that first object laser range sensor at a time exports is infinity, It can then determine that reference object does not reach the corresponding point distance measurement of first object laser range sensor at the moment；If first object The distance value that laser range sensor at a time exports is finite value, then can determine that reference object reaches at the moment The corresponding point distance measurement of first object laser range sensor.Therefore, if first object laser range sensor is defeated at current time Distance value out is finite value, is infinity in the distance value of previous moment output, then can determine reference object when current First object laser range sensor corresponding point distance measurement is reached exactly to quarter.Therefore, preset value can be a very big value, To guarantee distance value that first object laser ranging module exports respectively in current time and previous moment, one is finite value, One is infinity.

In the embodiment of the present application, the shooting that the adjustment mode of camera module shooting frame rate can be realized according to actual needs Effect determines.For example, to realize slow motion video shooting, and the first shooting frame rate is identical as the play frame rate of video, then may be used To determine that the second shooting frame rate is greater than the first shooting frame rate, i.e., the shooting frame rate of camera module is adjusted to biggish value；To Realize fast motion video capture, and the first shooting frame rate is identical as the play frame rate of video, then can determine the second shooting frame rate Less than the first shooting frame rate, i.e., the shooting frame rate of camera module is adjusted to lesser value.

For example, as shown in Fig. 2-2, the position of the corresponding first object laser range sensor of preset trigger position For a, current time is the T1 moment, and previous moment is the T0 moment, and preset value 10000, the shooting effect for needing to realize is slow motion It shoots.The distance value that first object laser range sensor exports at the T0 moment is infinity, i.e., reference object is at the T0 moment A point is not reached, is 100 in the distance value that the T1 moment exports, i.e. reference object reaches a point at the T1 moment, then can determine the One target laser distance measuring sensor is greater than preset value in the difference of current time T1 and previous moment the T0 distance value exported respectively, The shooting frame rate of camera module can be adjusted to the second shooting frame rate, and the second shooting frame rate is greater than the broadcasting frame of video Rate.

In a kind of possible way of realization of the embodiment of the present application, preset triggering can also be reached according to reference object Performed movement when position determines the second shooting frame rate of camera module.

Below with reference to Fig. 3, another video capture method based on laser ranging provided by the embodiments of the present application is carried out It further illustrates.

Fig. 3 is the process signal of video capture method of the another kind based on laser ranging provided by the embodiment of the present application Figure.

As shown in figure 3, the video capture method based on laser ranging of being somebody's turn to do, comprising the following steps:

Step 201, it during video capture, obtains first object laser range sensor in laser ranging module and is working as The distance value that preceding moment and previous moment export respectively, wherein include that multiple laser rangings sense in the laser ranging module Device, the first object laser range sensor are the corresponding laser range sensor of preset trigger position.

Step 202, judge what the first object laser range sensor exported respectively at current time and previous moment Whether the difference of distance value is greater than preset value, if so, executing step 203；Otherwise, 201 are returned to step.

The specific implementation process and principle of above-mentioned steps 201-202, is referred to the detailed description of above-described embodiment, herein It repeats no more.

Step 203, according to each laser range sensor of other in the laser ranging module the current time with before The distance value that one moment exported respectively determines the movement that reference object executes between the current time and previous moment.

In a kind of possible way of realization of the embodiment of the present application, it can also reach determining reference object at current time When preset trigger position, the movement executed between current time and previous moment according to reference object determines camera module The second shooting frame rate.Therefore, other in available laser ranging module in addition to first object laser range sensor The distance value that laser range sensor exports respectively at continuous multiple moment, with determine reference object current time and it is previous when The movement executed between quarter.

As a kind of possible implementation, can first according to other each laser range sensors at current time with before The distance value that one moment exported respectively determines that distance value is less than threshold value and each other current time of difference within a preset range Multiple third target laser distance measuring sensors corresponding with previous moment, and then distinguished according to current time and previous moment The position of corresponding multiple third target laser distance measuring sensors, determines reference object in the appearance at current time and previous moment State.

For example, as shown in Fig. 4-1 left figure, in previous moment T0, laser range sensor 6,7,10,11,14,15 is worked as The distance value of preceding output is respectively less than threshold value (as finite value), and each other difference within a preset range, i.e. laser range sensor 6,7,10,11,14,15 distance values that currently export are more consistent, the distance value currently exported with other laser range sensors There is significant difference, therefore, laser range sensor 6,7,10,11,14,15 can be determined as the corresponding third of previous moment T0 Target laser distance measuring sensor, later can according to the corresponding third target laser distance measuring sensor of previous moment T0 6,7,10, 11, the location of in 14,15 each laser range sensor in laser ranging module, determine reference object when previous The posture for carving the T0 moment is posture 1.

As shown in Fig. 4-1 right figure, in current time T1, laser range sensor 3,6,7,10,11,14,15 is currently exported Distance value be respectively less than threshold value (as finite value), and each other difference within a preset range, i.e., laser range sensor 3,6,7, 10,11,14,15 distance values that currently export are more consistent, have with the distance value that other laser range sensors currently export bright Aobvious difference, and between previous moment T0 and current time T1, laser range sensor 8 and 12 may export limited distance Value, it is possible to it can detect the movement of reference object, it therefore, can be true by laser range sensor 3,6,7,10,11,14,15 It is set to the corresponding third target laser distance measuring sensor of current time T1, it later can be according to the corresponding third mesh of current time T1 Mark the position locating in each laser range sensor in laser ranging module of laser range sensor 3,6,7,10,11,14,15 Set, determine reference object current time T1 posture be posture 2.

In the embodiment of the present application, determine reference object after the posture of current time and previous moment, it can Posture according to reference object at current time and previous moment determines the reference object between current time and previous moment The movement of execution.

For example, as shown in Fig. 4-1 left figure, determine reference object previous moment T0 posture be posture 1, such as scheme Shown in 4-1 right figure, determine that reference object in the posture of current time T1 is posture 2, then it can be true according to posture 1 and posture 2 It makes, the movement that reference object executes between previous moment T0 and current time T1 is " raising one's hand ".

It should be noted that the example above is exemplary only, the limitation to the application cannot be considered as.In actual use, Reference object can be preset according to actual needs in the posture of current time and previous moment and at current time and previous moment Between the mapping relations of movement that execute, the embodiment of the present application do not limit this.

Step 204, the movement executed between the current time and previous moment according to the reference object determines institute State the second shooting frame rate.

Step 205, the camera module is adjusted by the first shooting frame rate to the second shooting frame rate.

As a kind of possible implementation, it can be acted with goal-selling and target action is corresponding with shooting frame rate Relationship.After determining movement that reference object executes between current time and previous moment, that is, it can determine whether preset mesh In mark movement, if including the movement that reference object executes between current time and previous moment, if including, further root According to the corresponding relationship of target action and shooting frame rate, the movement that reference object executes between current time and previous moment is determined Corresponding shooting frame rate, and the shooting frame rate determined is determined as the second shooting frame rate；If not wrapped in preset target action The movement that reference object executes between current time and previous moment is included, then the second shooting frame rate is in current screening-mode Second shooting frame rate of default.

It in the embodiment of the present application, can be by the bat of camera module after the second shooting frame rate for determining camera module Frame per second is taken the photograph to adjust from the first shooting frame rate to the second shooting frame rate.

It further, can also be by the shooting frame rate of camera module from second after being completed to specific movement shooting Shooting frame rate is adjusted to the first shooting frame rate.I.e. in a kind of possible way of realization of the embodiment of the present application, above-mentioned steps 205 it Afterwards, can also include:

Monitoring the first object laser range sensor at a distance from current time exports respectively with previous moment When the difference of value is greater than the preset value again, the camera module is adjusted by second shooting frame rate to the first count Take the photograph frame per second.

It is understood that when first object laser range sensor current time and previous moment export respectively away from When difference from value is greater than preset value again, then can determine first object laser range sensor current time export away from It is infinity from value, i.e., first object laser range sensor can't detect reference object at current time, so as to true Determine reference object and passed fully through preset trigger position, it can the shooting frame rate of camera module is adjusted to original shooting Frame per second.

For example, Fig. 4-2 is the schematic diagram for realizing slow motion video shooting.As shown in the Fig. 4-2, preset trigger position The position of corresponding first object laser range sensor be a, the T1 moment after the T0 moment, the T2 moment after the T1 moment, Preset value is 10000, and the shooting effect for needing to realize is slow motion shooting.First object laser range sensor is defeated at the T0 moment Distance value out is infinity, i.e., reference object does not reach a point at the T0 moment, is 100 in the distance value that the T1 moment exports, that is, claps It takes the photograph object and reaches a point at the T1 moment, then can determine that first object laser range sensor is distinguished at T1 moment and T0 moment The difference of the distance value of output is greater than preset value, it can the shooting frame rate of camera module is adjusted to the second shooting frame rate, and Second shooting frame rate is greater than the play frame rate of video；When reaching the T2 moment, first object laser range sensor is defeated at the T2 moment Distance value out is infinity, i.e., reference object can then determine first object laser ranging at the T2 moment completely by a point Sensor is greater than preset value in the difference for the distance value that T2 moment and T1 moment export respectively, it can by the shooting of camera module Frame per second is adjusted to the first shooting frame rate, i.e., the shooting frame rate of camera module is adjusted back to original frame per second.

Video capture method provided by the embodiments of the present application based on laser ranging, can obtain during video capture The distance value that first object laser range sensor exports respectively at current time and previous moment in laser ranging module is taken, and It is greater than preset value in the difference for the distance value that first object laser range sensor exports at current time with previous moment respectively When, it is exported respectively at the current time with previous moment according to each laser range sensor of other in the laser ranging module Distance value, determine the movement that reference object executes between current time and previous moment, worked as later according to reference object The movement executed between preceding moment and previous moment determines the second shooting frame rate, and then by camera module by the first shooting frame rate It adjusts to the second shooting frame rate.Reference object is being determined when reaching preset trigger position at current time as a result, according to shooting The movement that object executes between current time and previous moment, determines the second shooting frame rate, to can not only accurately control The adjustment opportunity of camera module shooting frame rate improves the quality of the video capture comprising a variety of shooting frame rates, and can root The shooting that different shooting frame rate videos are realized according to the movement that reference object executes, improves the diversity of visual form, further Improve user experience.

As a kind of possible implementation, camera module and reference object can be measured with default control laser ranging module Between distance value time interval and default adjacent moment between the opposite laser range sensor of reference object variation and bat Take the photograph the mapping relations of object movement speed.For example, between preset laser ranging module measurement camera module processed and reference object The time interval of distance value is t, and the time interval between previous moment t0 and current time t1 is t, if at the t0 moment, laser ranging The distance value that sensor 4,7,8,11,12,16 exports is finite value, and the distance value of other laser range sensors output is infinite Greatly, and at the t1 moment, the distance value that laser range sensor 3,6,7,10,11,15 exports is finite value, other laser rangings pass The distance value of sensor output is infinity, then according to the opposite laser range sensor of reference object between preset adjacent moment The mapping relations of variation and reference object movement speed can determine that the movement speed of reference object is V₁；If swashing at the t0 moment The distance value that ligh-ranging sensor 4,7,8,11,12,16 exports is finite value, the distance value of other laser range sensors output For infinity, and at the t1 moment, the distance value that laser range sensor 2,5,6,9,10,14 exports is finite value, other laser The distance value of distance measuring sensor output is infinity, then is passed according to the opposite laser ranging of reference object between preset adjacent moment The variation of sensor and the mapping relations of reference object movement speed can determine that the movement speed of reference object is V₂, and V₂It is greater than V₁。

It should be noted that the example above is exemplary only, the limitation to the application cannot be considered as.In actual use, The distance value exported respectively according to each laser range sensor at current time and previous moment can be preset according to actual needs, Determine that the mode of the movement speed of reference object, the embodiment of the present application do not limit this.

Step 304, according to the movement speed of the reference object, second shooting frame rate is determined.

It in the embodiment of the present application, can be according to the movement of reference object after the movement speed for determining reference object Speed determines the second shooting frame rate of camera module.Specifically, to realize slow motion shooting, the then mobile speed of reference object Degree is bigger, then the second shooting frame rate of camera module can be larger, so that the slow motion video of shooting is finer；Shooting pair The movement speed of elephant is smaller, then the second shooting frame rate of camera module can be larger, to guarantee slow motion video more fineness While, reduce the performance requirement to electronic equipment.

Step 305, the camera module is adjusted by the first shooting frame rate to the second shooting frame rate.

The specific implementation process and principle of above-mentioned steps 305, are referred to the detailed description of above-described embodiment, and word is herein not It repeats again.
