Matching value order from high to low is arranged, and corresponding matching value highest, the figure of most m objects
As being sent to cloud server.Wherein, m >=1, and n is integer.Above-mentioned preset value can be in advance by opening
One matching threshold of the personnel of sending out setting, the matching value of certain object is more than this preset value, then this object is described
It is likely to be destination object, can subsequently be identified.
Additionally, in order to control the quantity sending image, threshold value m can also be arranged, when identifying every time,
The most multidirectional cloud server sends the image of m object.When the number of objects of the matching value higher than preset value is big
When m, the image of matching value highest m object is sent to cloud server；When higher than preset value
When the number of objects of matching value is less than m, then it corresponding matching value is higher than the image of all objects of preset value
All it is sent to cloud server.
Step 605, cloud server is higher than that the image of the object of preset value carries out image to this corresponding matching value
Identification, to detect that whether this corresponding matching value is higher than the object of preset value as destination object.
