Abstract
Provided is an identity recognition method of a system with multiple measurement cameras. An upper computer sends a camera identity recognition code to each measurement camera three times in a row, each measurement camera confirms the received identity recognition code, if the received identity recognition codes are valid, parameters and the installation method of each camera are selected, and meanwhile each received identity recognition code is sent to the upper computer; if invalid, the received identity recognition codes are directly sent to the upper computer; if the upper computer judges that the identity confirmation of the measurement cameras is successful three times in a row, measurement data are started to be obtained from each measurement camera. According to the identity recognition method of the system with the multiple measurement cameras, the measurement cameras are the same, so that development and technical state control of products are facilitated. When the system is used, the measurement cameras do not need to be changed when exchanged for use, and the interchangeability of the measurement cameras is improved when the system is used.
Description
Technical field
The present invention relates to a kind of personal identification method, particularly a kind of personal identification method of measuring camera system more.
Background technology
In some systems, can configure some measurement cameras measured target is measured, the host computer in system carries out correlation computations by the measurement result of obtaining each measurement camera.Because can making some parameters of camera, the factors such as production process there is otherness because measuring camera; In addition, measure camera measured target is carried out to relevant information while resolving and the installation position of measurement camera in system closely related, every camera must correctly use actual installation azimuth information separately just can calculate correct measurement result.Therefore, in fact the otherness of camera parameter and installation position can cause the inconsistent of every measurement camera Product Status, the system common practices of many measurement cameras of configuration is exactly to carry out development and design by each the specific parameter of measurement camera and fixing installation position at present, the major defect that this method exists:
(1) every measurement camera state is all inconsistent, is unfavorable for product state control;
(2) installation position of measuring camera, by a certain constant bearing design, exchanges if measure camera installation position with other, need to change indoor design, and interchangeability is poor;
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, a kind of personal identification method of measuring camera system is provided more, in the configuration systems of measuring camera more, guarantee under the state of the art uniform condition of each measurement camera, complete the confirmation of camera parameter and the installation position of each measurement camera, improved the interchangeability of each measurement camera in system.
Technical solution of the present invention is: a kind of personal identification methods of measuring camera system more, and step is as follows:
(1) after system is respectively measured camera and started working, host computer sends camera identity code to every measurement camera, and described identity code comprises parameter identity code and installation position identity code;
(2) every measurement camera is confirmed the identity code of receiving, if the identity code of receiving is effective, it is identical to be that host computer sends to identity code that system respectively measures camera and predefined system respectively to measure camera identity code, select camera parameter and installation position, the identity code of receiving is sent to host computer simultaneously; If the identity code of receiving is invalid, to send to identity code that system respectively measures camera and predefined system respectively to measure camera identity code not identical for host computer, directly the identity code of receiving sent to host computer; Thereby described camera parameter is the data that each measurement camera need to be bound because of the otherness of production process generation in product; Described installation position is system each installation position information of measuring camera while using, for measuring that camera is identified measurement target and the resolving of measurement result;
(3) host computer is respectively measured to the system receiving the identity code that camera returns and is judged, if it is identical with the identity code that host computer sends that system is respectively measured the identity code that camera returns, execution step (4), if it is not identical with the identity code that host computer sends that system is respectively measured the identity code that camera returns, execution step (1);
(4) perform step again (1)～step (2) twice, host computer acquisition system is respectively measured the identity code returning for the second time and for the third time of camera, if respectively to measure the identity code that camera returns identical with the identity code that host computer sends with system for the third time for the second time, judge and measure camera identification success, execution step (5); If respectively measure for the second time and for the third time in the identity code that identity code that camera returns sends with host computer once not identical or twice all not identical, execution step (1);
(5) host computer starts respectively to measure camera from system and obtains measurement data.
Host computer described in step (1) returns to host computer to the identity code by receiving described in every measurement camera transmission camera identity code and step (2) and completes by universal serial bus, host computer and each measurement camera carry out information interaction by universal serial bus, and described information is camera identity code.
It is identical that system described in above-mentioned steps is respectively measured camera.
The present invention's beneficial effect is compared with prior art:
(1) in the time of the many measurements of configuration camera system, in system, the state of the art of each measurement camera is consistent, is conducive to development and the state of the art control of product;
(2), in the time that system is used, exchange use if respectively measure camera, without carrying out any change to measuring camera, improved measuring the interchangeability of camera in the time that system is used;
(3), in identification, having designed measurement camera needs the continuous successfully rear host computer of identifying for three times just to judge identity validation success, has improved the reliability of identifying.
