[ detailed description ] embodiments
For better understanding of the technical solutions in the present specification, the following detailed description of the embodiments of the present application is provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only a few embodiments of the present specification, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step are within the scope of the present specification.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the specification. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Fig. 1 is a schematic structural diagram of a conventional scanning pen according to an embodiment of the present disclosure. Fig. 1 includes a housing 101, a main control chip 102 disposed in the housing 101, and a first camera 103 electrically connected to the main control chip 102. The first camera 103 is mainly used for executing a scanning task under the control of the main control chip 102. It should be understood that the first camera 103 is also disposed inside the housing 101.
The inventor of the application researches and discovers that the gesture habits of different users holding the scanning pen may be different, which causes different inclination angles of the scanning pen when in use. However, when the scanning pen executes a scanning task based on only the first camera 103, the first angle of view range α 1 corresponding to the first camera 103 is small, that is, the scanning pen itself can only maintain high scanning accuracy within a small range of the tilt angle, and once the user uses the scanning pen to set the tilt angle of the scanning pen in a large state, the text content scanned by the first camera 103 is distorted, so that the scanning accuracy of the scanning pen is reduced.
According to the analysis, in the prior art, the scanning pen can only be used in a smaller inclination angle, and cannot meet the use habits of different users.
In view of this, the embodiment of the present application provides a scanning pen, where the scanning pen configures two cameras, and it is ensured that viewing angle ranges between the two cameras partially overlap, and under the control of the main control chip, the first camera and the second camera can be used to accurately scan content to be scanned in respective corresponding tilt angle ranges, that is, an available tilt angle range of the scanning pen is a superposition of the tilt angle range corresponding to the first camera and the tilt angle range corresponding to the second camera, so as to improve the available tilt angle range of the scanning pen.
The scanning pen provided by the embodiment of the application is described in detail below with reference to the attached drawings of the specification. Referring to fig. 2, a novel scan pen provided in an embodiment of the present invention includes: the scanning system comprises a shell 101, a main control chip 102 arranged inside the shell 101, and a first camera 103 and a second camera 104 which are respectively electrically connected with the main control chip 102, wherein a target included angle is configured between the first camera 103 and the second camera 104, so that a first visual angle range alpha 1 corresponding to the first camera 103 and a second visual angle range alpha 2 corresponding to the second camera 104 are partially overlapped, and the main control chip 102 is used for controlling the first camera 103 and the second camera 104 to jointly execute a scanning task.
In the embodiment of the present application, a first camera 103 and a second camera 104 are disposed in a housing 101 of a scan pen, and the first camera 103 and the second camera 104 are configured to form a target included angle. Under the target angle, a first view angle range α 1 corresponding to the first camera 103 and a second view angle range α 2 corresponding to the second camera 104 are partially overlapped. For example, the first viewing angle range α 1 and the second viewing angle range α 2 intersect with each other on a line on the text region to be scanned, that is, the first viewing angle range α 1 and the second viewing angle range α 2 are in a tangent state, or the first viewing angle range α 1 and the second viewing angle range α 2 intersect with each other on a sub-region of the text region to be scanned, where a partially overlapping state of the first viewing angle range α 1 and the second viewing angle range α 2 is not particularly limited.
It should be understood that the first angle of view α 1 corresponding to the first camera 103 and the second angle of view α 2 corresponding to the second camera 104, which are disposed in the scanning pen, may be the same, for example, the first angle of view α 1 and the second angle of view α 2 are both 60 degrees. Of course, the first viewing angle range α 1 and the second viewing angle range α 2 may be different, for example, the first viewing angle range α 1 is 60 degrees, the second viewing angle range α 2 is 50 degrees, and in the present application, no particular limitation is imposed on whether the first viewing angle range α 1 is the same as the second viewing angle range α 2, and specific values of the first viewing angle range α 1 and the second viewing angle range α 2 are the same.
After the first camera 103 and the second camera 104 are configured to have the above target included angle, the first camera 103 and the second camera 104 can execute a scanning task within the respective corresponding tilt angle range under the control of the main control chip 102. Since the sum of the first angle of view range α 1 corresponding to the first camera 103 and the second angle of view range α 2 corresponding to the second camera 104 is greater than the first angle of view range α 1 corresponding to the first camera 103, which is used only in the prior art, the available tilt angle range of the novel stylus (the superposition of the available tilt angle range corresponding to the first camera 103 and the available tilt angle range corresponding to the second camera 104) is greater than the available tilt angle range corresponding to the existing stylus when only the first camera 103 is used. That is, compared with the existing scanning pen, the novel scanning pen can keep higher scanning accuracy in a larger inclination angle range.
It should be understood that the portion of the housing corresponding to the second camera 104 should be shorter in the length direction so as to avoid causing obstruction to the second camera 104. The length of the portion of the housing corresponding to the second camera 104 is not particularly limited. Meanwhile, a scanning window is disposed below the housing 101, and a transparent medium, such as transparent glass or transparent plastic, is mounted on the scanning window, so that the scanning definition is ensured when the first camera 103 and the second camera 104 are protected.
In some embodiments, it is considered that the holding posture of the same user may change during the use of the novel scanning pen, or the holding posture of different users may be different during the use of the same novel scanning pen, so that the tilt angles of the scanning pen during the work are different. Because the two cameras (the first camera 103 and the second camera 104) that dispose among the novel wand are fixed when installing inside casing 101, and the inclination that novel wand self was located is different, can lead to installing the relative distance between the two cameras in casing 101 and treating the scanning text region to change for the scanning accuracy of novel wand reduces.
Therefore, in the embodiment of the present application, the two cameras (the first camera 103 and the second camera 104) installed in the housing 101 of the novel scan pen may have a zoom function, so that when a relative distance between any one of the cameras and a text area to be scanned changes, a focal length of the camera can be changed in time under the control of the main control chip 102, thereby ensuring scanning accuracy.
As a possible implementation, the first camera 103 and the second camera 104 both employ zoom cameras.
In some embodiments, it is considered that when the first camera 103 and the second camera 104 in the new scanning pen perform scanning tasks together, scanning accuracy may be poor due to insufficient light.
Therefore, in the embodiment of the application, the corresponding light supplement device can be arranged inside the novel scanning pen, so that light rays which are good when the double cameras execute scanning tasks are guaranteed, and scanning accuracy is guaranteed.
As a possible implementation manner, a first supplementary lighting lamp may be disposed inside the novel scanning pen, the first supplementary lighting lamp is electrically connected to the main control chip 102, and when the first camera 103 executes a scanning task under the control of the main control chip 102, the main control chip 102 may also control the first supplementary lighting lamp to supplement lighting for the scanning process of the first camera 103; similarly, the inside second light filling lamp that can also set up of novel wand, this second light filling is connected with main control chip 102 electricity, and when second camera 104 executed the scanning task under main control chip 102's control, main control chip 102 also can control the second simultaneously and supply the lamp to carry out the light filling to the scanning process of second camera 104.
In some embodiments, it is considered that specifications of the first camera 103 and the second camera 104 may not be the same when different manufacturers manufacture the new stylus. For example, a first view angle range α 1 corresponding to the first camera 103 purchased by the factory a is 60 degrees, and a second view angle range α 2 corresponding to the second camera 104 is also 60 degrees; the first visual angle range α 1 corresponding to the first camera 103 purchased by the plant B is 70 degrees, and the second visual angle range α 2 corresponding to the second camera 104 is also 70 degrees, so that the plant B cannot perform the production of the novel scanning pen according to the process parameters of the plant a.
Therefore, in the embodiment of the present application, a corresponding relationship between the target included angle formed between the first camera 103 and the second camera 104 and the respective viewing angle ranges of the first camera 103 and the second camera 104 can be established, so that when the first camera 103 and the second camera 104 with different viewing angle ranges are selected, the target included angle can be simply adjusted to meet the production requirements of different manufacturers.
As a possible implementation manner, the target included angle formed between the first camera 103 and the second camera 104 is positively correlated to the first viewing angle range α 1 and the second viewing angle range α 2.
Fig. 3 is a schematic partial enlarged view of a first camera 103 and a second camera 104 in a novel scan pen according to an embodiment of the present disclosure. The target included angle formed between the first camera 103 and the second camera 104 is β. It should be understood that the target included angle β is an included angle formed between the installation position of the second camera 104 and the installation position of the first camera 103 with reference to the installation position of the first camera 103, and the target included angle β is positively correlated to the first viewing angle range α 1 and the second viewing angle range α 2.
In some embodiments, considering that a user may not change a holding posture when using the above-mentioned novel stylus pen, except that the novel stylus pen is at a specific angle or a specific angle interval, the first camera 103 and the second camera 104 may execute a scanning task together, otherwise, only the first camera 103 or the second camera 104 actually executing the scanning task in the novel stylus pen may be, if the first camera 103 and the second camera 104 are both in an operating state when the novel stylus pen is in an on state, the power consumption of the novel stylus pen may be higher.
Therefore, in the embodiment of the application, the novel scanning pen can dynamically open the camera which should be used under the inclination angle according to the current inclination angle of the novel scanning pen, so as to complete the scanning task. Namely, on the basis of ensuring the completion of the scanning task, the power consumption of the novel scanning pen is reduced as much as possible.
As a possible implementation manner, a tilt angle detection device may be included in the novel stylus pen, and the tilt angle detection device is electrically connected to the main control chip 102 and may be used to detect an actual tilt angle at which the novel stylus pen is currently located. The main control chip 102 stores a corresponding relationship between the tilt angle and the camera in advance, and after the main control chip 102 obtains the current actual tilt angle of the novel scanning pen, the target camera which is required to be used by the novel scanning pen at present can be determined based on the corresponding relationship. It should be understood that the target camera here is the first camera 103 and/or the second camera 104.
For example, the corresponding relationship between the tilt angle pre-stored in the main control chip 102 and the camera is as follows: when the novel scanning pen is in the inclination angle range of (70 degrees and 90 degrees), the first camera 103 is used alone to execute the scanning task, when the novel scanning pen is in the inclination angle range of 70 degrees, the first camera 103 and the second camera 104 are used together to execute the scanning task, and when the novel scanning pen is in the inclination angle range of [50 degrees and 70 degrees ], the second camera 104 is used alone to execute the scanning task.
If the main control chip 102 learns that the actual tilt angle of the current scanning pen is 60 degrees, the second camera 104 is independently controlled to execute a scanning task; or, if the main control chip 102 learns that the actual tilt angle of the current scanning pen is 75 °, the first camera 103 is controlled independently to execute the scanning task; if the main control chip 102 knows that the actual tilt angle of the current scanning pen is 70 °, the first camera 103 and the second camera 104 are controlled to jointly execute the scanning task.
For another example, the corresponding relationship between the tilt angle pre-stored in the main control chip 102 and the camera is as follows: when the novel scanning pen is in the inclination angle range of (70 degrees and 90 degrees), the first camera 103 is used alone to execute the scanning task, when the novel scanning pen is in the inclination angle range of [65 degrees and 70 degrees ], the first camera 103 and the second camera 104 are used together to execute the scanning task, and when the novel scanning pen is in the inclination angle range of [50 degrees and 65 degrees ], the second camera 104 is used alone to execute the scanning task.
If the main control chip 102 learns that the actual tilt angle of the current scanning pen is 60 degrees, the second camera 104 is independently controlled to execute a scanning task; or, if the main control chip 102 learns that the actual tilt angle of the current scanning pen is 75 °, the first camera 103 is controlled independently to execute the scanning task; or, if the main control chip 102 knows that the actual tilt angle of the current scanning pen is 68 °, it controls the first camera 103 and the second camera 104 to jointly execute the scanning task.
In some embodiments, considering that the text area to be scanned by the new scanning pen is mainly a black-and-white area, in the embodiments of the present application, a specific camera may be configured for the new scanning pen for a specific scene, so as to ensure the accuracy of scanning,
as a possible implementation manner, the first camera 103 and the second camera 104 in the novel scanning pen both adopt black and white cameras, and the black and white cameras do not have color filters, so that the light sensing performance is greatly improved, the resolution is higher, and the scanning accuracy is favorably improved.
It should be understood that if there is a need for scanning color texts in an application scene targeted by the novel scanning pen, the first camera 103 and the second camera 104 may also adopt color cameras, and what type (black and white camera or color camera) the first camera 103 and the second camera 104 specifically adopt in this application may be determined according to the specific application scene, and is not particularly limited herein.
