If the construction period is not up to the construction period, the subsequent construction process is influenced, and the subsequent pre-sale period is seriously influenced. Therefore, it is especially important for project management personnel to know the progress of the project in time.
At present, managers want to know the construction progress of a project and mainly look up the project on site. On the one hand, the method is troublesome for managers, consumes time and labor, and on the other hand, because the items are large in size and small in change in a short time, even if the items are checked on site, if the frequency is high, intuitive change is difficult to perceive, and if the frequency is low, the control on the construction period of the items is difficult.
Therefore, some projects can collect the construction progress by photographing and field measurement of technicians, and then send the collected data to managers. However, this method requires a special technician to frequently perform on-site measurement, and is troublesome to operate.
Therefore, there is a need for an image collecting and analyzing system and method for project progress, which enables a manager to conveniently and accurately know the progress of the project.

Example two
Compared with the first embodiment, the difference is that the second embodiment further comprises a second acquisition end, which is used for acquiring images and voice of the construction site and sending acquired data to the server. The storage unit stores face information and telephone of workers and also stores interpersonal relationship among workers at the same construction site. The second acquisition end is a camera and a sound pickup.
The server also comprises an fighting analysis unit which is used for analyzing the data sent by the second acquisition end in an image recognition and semantic recognition mode, when the analysis result is that the two people have fighting risks, after the facial information of the two people is recognized, the two people are matched, preset calling messages are sent to the two people respectively, the message content of one of the two people is called to the place A by the shop head, the message content of the other one of the two people is called to the place B by the monitor, and the A and the B are located at two ends of the building site.
If the call message is sent for X minutes, the analysis unit of the fighting analysis unit still has fighting risks for the same two people and an onlooker scene appears. The fighting analysis unit analyzes Y workers having common relations with both parties involved as persuasists from the storage unit, matches the telephones of the Y persuasists, and then sends persuasists a message and a persuasion place to each persuasist. In this example, X has a value of 2 and Y has a value of 4.
The specific implementation process comprises the following steps:
due to the fact that tools are more in construction sites, the bodies of workers are more exquisite, and if a fighting event happens, an injury event can easily occur.
Therefore, when the result of the analysis by the fighting analysis unit is that there is a risk of two people fighting, the fighting analysis unit recognizes the face information of the two people and matches the phones of the two people. And then, the fighting analysis unit respectively sends voice messages to the two people, wherein the message content of one person is that the workhead calls to a place A, the message content of the other person is that the monitor calls to a place B, and the place A and the place B are positioned at two ends of the construction site.
In such a way, two workers involved in the affairs are called to the two ends of the construction site, the workers are allowed to be cool, the fighting event is prevented from happening, then the management personnel carry out education, and the workers involved in the affairs absorb teaching and training.
If the call message is sent for 2 minutes, the analysis unit of the fighting analysis unit still has fighting risks for the same two people, and the scenery is seen. It is stated that the event is not only not alleviated, but the scene is rather more confusing. Therefore, the blast analysis unit analyzes 4 workers who are related to both people involved as blast persons from the storage unit, matches the telephones of 4 blast persons, and then sends blast messages and blast locations to each blast person. The relation between 4 dissuading persons and both parties is general, can prevent to appear pulling the condition of partially putting up, simultaneously because dissuading persons has 4, can prevent to appear dissuading the condition that putting up persons can not pull both parties. Before the true fighting occurs, the two parties involved are pulled apart as much as possible.
The foregoing is merely an example of the present invention, and common general knowledge in the field of known specific structures and characteristics is not described herein in any greater extent than that known in the art at the filing date or prior to the priority date of the application, so that those skilled in the art can now appreciate that all of the above-described techniques in this field and have the ability to apply routine experimentation before this date can be combined with one or more of the present teachings to complete and implement the present invention, and that certain typical known structures or known methods do not pose any impediments to the implementation of the present invention by those skilled in the art. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
