More specifically, the camera sends the captured area image, and the internal algorithm analyzes a large amount of data of the image to obtain whether the image includes hand features, but not limited to.
Step S102: and detecting whether a hand shape exists according to the first image data. Specifically, the hand pulse input device is provided with a machine learning model, the model can receive image data transmitted back by the camera, and whether the image contains a hand shape or not is judged through a large amount of data analysis, and the specific analysis process can refer to the prior art and is not repeated herein.
Step S103: when the hand shape exists, judging whether the first image data meets a preset condition, wherein the preset condition is a condition which is met by the position and/or the posture of the hand shape; specifically, when the image captured by the camera contains a hand, the gesture of the hand is verified, and the vein in the palm needs to be collected due to the hand vein input, so that the palm needs to be over against the camera, that is, the palm surface of the hand shape needs to be parallel to the mirror surface of the camera, and the verification of the hand shape posture needs to carry out a large amount of calculation on a machine learning model in the hand vein input equipment, if an angle exists between the palm surface of the hand shape and the mirror surface of the camera, the collection of the hand pulse is affected, so that the infrared rays reflected by veins from all parts of the palm are received by the hand pulse recording equipment and are calculated to construct a plan view of the hand, and then calculating a deviation value of the plane where the plane graph and the camera lens are located, so as to adjust the angle of the camera in time, so that the camera lens is parallel to the palm surface of the hand shape, but the method is not limited to this. In addition, after the palm center of the hand shape is parallel to the lens of the camera, the vein of the hand is not accurately collected because the camera is far away from the hand, and if the camera is too close to the hand, the vein of the hand cannot be collected, so that whether the distance between the camera and the hand shape is suitable needs to be judged.
Step S104: when the first image data does not meet the preset condition, controlling the camera to adjust the position according to the first image data so that the camera shoots in a second position posture to obtain second image data; specifically, if the position of the hand shape is deflected from the lens of the camera, or the distance between the camera and the hand shape is too close or too far, the camera needs to be controlled to adjust the position, and after the position is adjusted, the camera is used to shoot for the second time at the position, and the hand shape data at the position is acquired.
Step S105: receiving second image data sent by the camera as hand pulse information of a user; specifically, the second image data is hand shape data shot by the camera after the position is adjusted, the position at the moment is standard, and the collected hand vein data can be directly stored in the database.
Therefore, the hand shape is judged by detecting the first image data collected by the camera, whether the position and the posture of the hand shape meet the requirements is judged, if not, the position of the camera is adjusted to enable the position and the posture of the hand shape to meet the requirements, then the hand shape of the second pose is shot by the camera, and the image data of the second pose is used as the hand pulse information of the user.
In a specific implementation, the preset condition may include at least one of: the mirror surface of the camera is parallel or approximately parallel to the palm surface of the hand shape; the distance between the camera and the hand shape is within the preset range. Specifically, if there is an angle between the palm-shaped face and the lens surface of the camera, the collection of the hand veins may be affected, so that it is necessary to receive infrared rays reflected by veins from each part of the palm through a hand vein input device, calculate the infrared rays to construct a plan view of the hand, and then calculate a deviation value between the plan view and the plane where the lens surface of the camera is located, so as to adjust the angle of the camera in time, so that the lens surface of the camera is parallel to the palm-shaped face, but not limited thereto. In addition, after the palm center of the hand shape is parallel to the lens of the camera, the vein of the hand is not accurately collected because the camera is far away from the hand, and if the camera is too close to the hand, the vein of the hand cannot be collected, so that whether the distance between the camera and the hand shape is suitable needs to be judged.
Therefore, the accuracy of hand pulse acquisition can be improved by the parallel or approximately parallel of the lens surface of the camera and the palm surface of the hand shape; and the camera and the hand shape are positioned at a proper position, so that the accuracy of hand pulse acquisition can be improved to a certain extent.

Step S302: and controlling the camera to adjust the mirror surface of the camera to be parallel to the palm surface of the hand shape according to the deviation information. Specifically, the camera is adjusted according to the received deviation information, so that the mirror surface of the camera is parallel to the palm surface of the hand shape.
Therefore, the plane where the palm of the hand shape is located can be accurately positioned through establishment of the space coordinate system, so that deviation information between the palm surface and the mirror surface of the camera can be accurately obtained, then the mirror surface of the camera can be quickly adjusted to be parallel to the palm surface of the hand shape through the deviation information, and the hand vein recording efficiency is further improved.

The preset condition is that the distance between the camera and the hand shape is within the preset range. Step S104 includes step S401: and controlling the camera to adjust that the distance between the camera and the hand shape is within the preset range. Specifically, after the palm center of the hand shape is parallel to the lens of the camera, the vein of the hand is collected inaccurately because the camera is far away from the hand, and if the vein of the hand is too close to the palm center of the hand, the vein of the hand cannot be collected, so that whether the distance between the camera and the hand shape is suitable or not needs to be judged.
Therefore, the distance between the camera and the hand shape can be in a proper range only by adjusting the position of the camera, the hand shape does not need to be adjusted by a user, and the hand pulse acquisition efficiency is improved.
In a specific implementation, referring to fig. 5, the step S401 may include steps S501 to 502.
Step S501: receiving the current distance between the camera and the hand shape sent by a distance sensor; specifically, the distance sensor can collect distance information between the camera and the hand shape and send the distance information.
Step S502: according to current distance control the camera adjustment extremely the camera with distance between the hand shape is located predetermine the within range, it is concrete, after hand shape centre of the palm is in the parallel state with the camera lens, because the camera is far away from the hand can cause the inaccuracy of hand vein collection, if too near, then can lead to the possibility that can not gather the vein of whole hands, consequently, need judge whether distance between camera and the hand shape is suitable.
Therefore, the distance between the current position of the camera and the hand shape is calculated, whether the distance is in a proper range or not is judged, and if not, a corresponding instruction is generated and sent to the adjusting unit, so that the hand pulse recording efficiency is increased to a certain extent.
