Step S201, terminal starting App start to acquire image, and registration GPS positioning is monitored；
Step S202, terminal (1 second) readjustment GPS event according to the preset time interval, and camera is called to take pictures using journey Sequence programming interface (Application Programming Interface, API), waiting, which is taken pictures, completes readjustment；
Here, GPS time of terminal every 1 second readjustment obtains positioning result (x, y, bearing, v), wherein x is warp Degree, y is dimension, and bearing is driving direction, and v is travel speed.
Step S203 stores GPS information and corresponding image after completion readjustment of taking pictures.
Here, acquired image is generally the photo that camera applications are filmed in the related art, generally red green Blue (Red Green Blue, RGB) rgb format, and in other embodiments, acquired image is in camera applications preview frame Image, the image in preview frame is generally luminance color component signal (YUV) format.
The major defect of the image-pickup method used in the prior art is to be when carrying out Image Acquisition according to setting in advance What fixed time interval was taken pictures, in this way, when road element is acquired than comparatively dense or user, travel speed is too fast to lead Road element is caused not collect, to lose important information；Or cause to collect many redundancies when travel speed is excessively slow Image, cause Image Acquisition inefficiency.
The present embodiment provides a kind of image-pickup method, Fig. 3 is the implementation process of image-pickup method of the embodiment of the present invention Schematic diagram, as shown in figure 3, the described method comprises the following steps:
Step S301 obtains the first attribute information of image capture device when reaching the first current GPS positioning point and arrives Second attribute information of described image acquisition equipment when up to last Image Acquisition.
Here, the step S301 can be by image processing equipment realization, further, described image processing equipment It can be intelligent terminal, such as can be the movement that mobile phone (mobile phone), iPad, car-mounted terminal etc. have wireless communication ability Terminal.Image Acquisition App is installed in intelligent terminal, when starting Image Acquisition App, GPS positioning prison can be registered by App It listens, in this way, can get the attribute information of terminal after being spaced identical duration, it is usually 1 second that the GPS positioning of registration, which is monitored, (second, s) returns to a positioning result.When terminal reaches the first current GPS positioning point, the positioning result that gets That is the first attribute information of image capture device at this time, wherein where first attribute information can include but is not limited to terminal The location information of first GPS positioning point, driving direction, travel speed, the first time point for reaching the first GPS positioning etc., position Confidence breath can be longitude and latitude.
On the second attribute information of described image acquisition equipment may include when correspondingly, with reaching last Image Acquisition The location information on Image Acquisition ground, travel speed, the second time point for reaching last Image Acquisition ground.
It should be noted that last Image Acquisition may be GPS positioning point, it is also possible to be not GPS positioning point, and It is some point between two GPS positioning points.
Step S302 determines the first GPS positioning point according to first attribute information and second attribute information With first spacing distance on the last Image Acquisition ground.
Here, the step S302 can be by image capture device realization.
In practical applications, the step S302 can be realized by least two modes:
The first, determines the first interval distance according to the location information carried in the first attribute information and the second attribute information From；
Due to including the longitude and latitude of the first GPS positioning point in the location information that is carried in the first attribute information, second Include the longitude and latitude on last Image Acquisition ground in the location information carried in attribute information, it is known that the longitude of two points and Latitude can determine the distance between two o'clock.
It second, is determined according to the travel speed and time point information carried in the first attribute information and the second attribute information First spacing distance.
According to the time point carried in the first attribute information and the second attribute information, terminal can be determined from a upper image Locality to the mobile duration of the first GPS positioning point, then belonged to according to the First Speed carried in the first attribute information and second Property information in the second speed that carries and mobile duration according to even acceleration computation model can determine acceleration, then basis Mobile duration, acceleration and First Speed can determine that the first spacing distance.
Since even acceleration computation model in second of implementation, is utilized, but during actually realizing, image Acquisition equipment is difficult uniformly accelerated motion, and therefore, second of implementation has biggish error relative to the first implementation.
Step S303, according to the relationship between preset acquisition interval distance and first spacing distance, under determining The time of secondary Image Acquisition, and next Image Acquisition is carried out at the corresponding moment.
Here, the step S303 can be by image capture device realization.
In the present embodiment, the preset sampling interval distance can wrap with the relationship between first spacing distance It includes at least three kinds following:
The first relationship, the difference between acquisition interval distance and first spacing distance is greater than 0 and the difference is small In the 4th spacing distance, wherein the 4th spacing distance is between the first GPS positioning point and the second GPS positioning point Distance, the second GPS positioning point be the first GPS positioning point next GPS positioning point.
Difference between acquisition interval distance and first spacing distance is greater than 0 and the difference is spaced less than the 4th Apart from when, illustrate to be needed at this time between the first GPS positioning point and the second GPS positioning point next time The first interval duration when the Image Acquisition from currently counting to carrying out is calculated, and after waiting first is spaced duration, carries out image Acquisition.
In practical applications, the first interval duration can be determined by formula (1-1):
T=(N-D)/v1 (1-1)；
Wherein, t is the first interval duration, and D is the first spacing distance, and N is sampling interval distance, and v1 is First Speed, by Meet first condition in first spacing distance and sampling interval distance, i.e., 0 < (N-D) < v1*T, then, 0 < t < T, GPS are returned The period for returning positioning result is generally 1s, therefore, at this point, 0 < t < 1.
In the present embodiment and other embodiments, the first image that terminal obtains camera acquisition is adopted from the camera It is collected that current time camera is obtained in the preview frame collected.
The step S304 can be the timer of a length of first interval duration at setting one during realization, After reaching the first interval duration, collected first figure of current time camera is obtained from preview frame by a readjustment API Picture, this readjustment API can be setPreviewCallBackWithBuffer () in Android system.
Second of relationship, the difference between acquisition interval distance and first spacing distance are less than or equal to 0.
When difference between acquisition interval distance and first spacing distance is less than or equal to 0, illustrate the first GPS The distance on anchor point to last Image Acquisition ground has been not less than acquisition interval distance, needs to acquire image immediately at this time.
The third relationship, difference between acquisition interval distance and first spacing distance are more than or equal to described the Four spacing distances.
Difference between acquisition interval distance and first spacing distance is more than or equal to the 4th interval distance From when, that is to say, that still do not reach sampling interval distance when reaching next GPS positioning point, need at this time in the case where reaching The interval duration of Image Acquisition next time is calculated when one GPS positioning point.
In image-pickup method provided in an embodiment of the present invention, obtains reach the first current global positioning system first When GPS positioning point the first attribute information of image capture device and with reaching last Image Acquisition when described image acquire equipment The second attribute information；Then first GPS positioning is determined according to first attribute information and second attribute information First spacing distance of point and the last Image Acquisition ground；According to preset acquisition interval distance and first interval Relationship between distance determines the time of Image Acquisition next time, and carries out next Image Acquisition at the corresponding moment.It so, it is possible Image Acquisition is carried out according to equidistant intervals, to guarantee that acquired image does not omit not redundancy yet, and then improves figure As collecting efficiency.
