Embodiment 2:
Please refer to Fig. 2, the present embodiment provides a kind of detection method of quorum sensing inhibitor, comprising:
Step 201, takes pictures to object, draws photo.
Photo in the present embodiment is entity photo, i.e. in esse photo, certainly, also after taking pictures to object, can not draw entity photo, but must generating pictures data, i.e. generating virtual photo, for for needing the object of measurement size to focus.
Step 202, identifies the border pixel positions of object in photo, and carries out focusing to object and draw focus, the focus pixel position of record focus.
Specifically comprise:
Step 2021, identifies the border of object in photo.
That is, in comparison film, the border of object identifies, namely obtains the profile of this object.
Step 2022, the border pixel positions of record object.
Certainly, in comparison film, the border of object identifies, after obtaining the profile of this object, certainly exists the step first generating border pixel positions, then carries out record to border pixel positions.
Step 2023, carries out focusing to object and draws focus.
Be understandable that, when unique for the focus needing the object of measurement size automatically to generate, directly select this focus to focus; When not unique for the focus needing the object of measurement size automatically to generate, user needs to select a focus to focus in the focus automatically generated at these.Certainly, the position of focus is not limited to be positioned at this object center, as long as in the profile of this object.
Step 2024, the focus pixel position of record focus.
Certainly, after object being carried out to focusing and drawing focus, certainly exist the step that Mr. becomes focus location of pixels, then focusing location of pixels carries out record.
Step 203, according to focus, measures the distance between object and signal base station.
Be understandable that, because the equipment for taking pictures is in signal base station, therefore, the distance in focus and photo between object is the distance between signal base station and object, in general, the distance between object and signal base station is the vertical range between object and signal base station.

Be understandable that, signal wavelength can not change with the increase of distance, and after signal sends, signal wavelength can extend to all directions, just cannot extend along wavelength direction again, thus judge whether signal wavelength is blocked by object after running into shelter.Therefore, when after the height obtaining object and width, whether the signal wavelength detection signal that can be sent by signal base station is blocked by object.
Step 207, if detect, the signal wavelength of signal base station is blocked by object, calculates the position of object, and uploaded onto the server the position of object according to the GPS location of signal base station.
Particularly, GPS location due to signal base station is known, and the border of Distance geometry object between object and signal base station and focus are also obtained by above-mentioned steps relative to the angle ∠ α of signal base station, therefore, just can calculate the position of object based on the GPS location of signal base station, Distance geometry angle ∠ α between object and signal base station, then be uploaded onto the server by the position of signal base station by object.
Step 208, the signal base station adjacent with signal base station continues to perform step 201.
After the position of object uploads onto the server by the signal base station that signal is blocked (being called for short signal base station A), other signal base stations (being called for short signal base station B) that server meeting " notice " is adjacent with signal base station A, certainly, adjacent with signal base station A signal base station is not unique.Signal base station B is after receiving " notice " of server, the signal whether this object being blocked to this signal base station B detects, namely above-mentioned steps 201 to step 207 is repeated, if detect, the signal of signal base station B is blocked by this object, then continue announcement server, whether other signal base station detection signals are blocked by this object.If other signal base stations adjacent with signal base station A all detect that this object has blocked signal, then server can obtain this information.
