Abstract
The invention relates to a method for realizing automatic shooting by utilizing bar code reader field depth characteristic. The method includes the following steps: control information used for triggering a camera to shoot is written into a bar code; the bar code is added with the object to be shot; field depth matching is carried out on bar code accuracy and a bar code reader to determine optimal distance of the bar code reader and the object to be shot; the object to be shot passes through the camera at the front of the camera; if the object to be shot appears in the field depth range of the bar code reader, the additional bar code thereof is read by the bar code reader, so as to trigger the camera to shoot; and if the object to be shot does not appear in the field depth range, the camera can not be triggered. Compared with the prior art, the invention has the following advantages: accuracy of bar code reader to bar code is utilized, reading range restriction characteristic is realized, optimal matching of image reading equipment and relative position of the object to be shot is realized, shooting effect is ensured, and application requirement is met.
Description
Technical field
The present invention relates to information technology, automatic identification technology field, relate in particular to and utilize bar code reader field depth characteristic to realize the method for automatic shooting.
Background technology
In the bar code in automatic identification technology field is used, also have a lot of application not develop, for example with bar code as Controlling Source, the opportunity of utilizing bar code reader field depth characteristic control to take, for now some need to take in real time but situation that again can not fine control shooting distance is very practical.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the defective that above-mentioned prior art exists, to provide a kind of easy to operate bar code reader field depth characteristic that utilizes to realize the method for automatic shooting.
Purpose of the present invention can be achieved through the following technical solutions: utilize bar code reader field depth characteristic to realize the method for automatic shooting, it is characterized in that this method may further comprise the steps:
(1) will trigger the control information that filming apparatus takes and write bar code;
(2) bar code and subject are added;
(3) bar code precision and bar-code reader are carried out field depth matching, determine the optimum distance between bar-code reader and the subject;
(4) allow subject before filming apparatus, pass through;
(5) if subject appears in the bar code reader field depth scope, then its add-on is distinguished by bar-code reader, and then triggers filming apparatus and take;
(6) if subject does not appear at the subject in the field depth, then can't trigger filming apparatus and take.
Described bar code comprises bar code, two-dimensional bar code or OCR font literal.
Described bar code adopts and prints, pastes or rotten mode and the subject of carving adds.
Described bar-code reader is located at the camera lens place.
Compared with prior art, the present invention has the following advantages: utilize the precision of bar-code reader to bar code, have the characteristics of recognition scope restriction, realize that the relative position of the image reading device and the article that are taken is realized best fit, guarantee shooting effect, satisfy the needs of using.
Description of drawings
Fig. 1 is that the present invention utilizes bar code reader field depth characteristic to realize the schematic diagram of the method for automatic shooting.
Embodiment
The present invention will be further described below in conjunction with specific embodiment.
Embodiment 1
As shown in Figure 1, among the present invention, generate software by the Codesoft bar code, generation comprises the bar code graphics of control information and is printed on 2.5 centimetres high by 888 type bar code printers, on the 5 centimetres wide art paper label, make the label (A1, A2, A3) of three same precision.Its content is variant mutually, so that distinguish.
Bar-code label is sticked on article (B1, B2, B3) surface respectively subsequently.Utilize MS-890 (C) to bar-code label, focus, determine that the best reads the position, adjust the position of shooting focal length object.Use MS-890 (C) that the bar-code label of object is monitored, in label appeared at MS-890 (C) zone, bar code A2 was distinguished, and triggered filming apparatus and took action, got access to optimal picture.When article do not occur in sweep limits, at this time just can't trigger and take action, just do not have ropy picture yet and be taken.
Claims (4)
1. utilize bar code reader field depth characteristic to realize the method for automatic shooting, it is characterized in that this method may further comprise the steps:
(1) will trigger the control information that filming apparatus takes and write bar code;
(2) bar code and subject are added;
(3) bar code precision and bar-code reader are carried out field depth matching, determine the optimum distance between bar-code reader and the subject;
(4) allow subject before filming apparatus, pass through;
(5) if subject appears in the bar code reader field depth scope, then its add-on is distinguished by bar-code reader, and then triggers filming apparatus and take; If subject does not appear in the field depth, then can't trigger filming apparatus and take.
2. the method for utilizing bar code reader field depth characteristic to realize automatic shooting according to claim 1 is characterized in that described bar code comprises bar code, two-dimensional bar code or OCR font literal.
3. the method for utilizing bar code reader field depth characteristic to realize automatic shooting according to claim 1 is characterized in that, described bar code adopts and prints, pastes or rotten mode and the subject of carving adds.
4. the method for utilizing bar code reader field depth characteristic to realize automatic shooting according to claim 1 is characterized in that described bar-code reader is located at the camera lens place.
