Description

Technical Field

[0001] The utility model relates to the technical field of information collection and identification, in particular to a ten-finger fingerprint rapid non-contact collection device. Background Art

[0002] Traditional general fingerprint collection equipment can usually only collect flat fingerprints and rolled fingerprints separately. This separate collection method brings the following problems:

[0003] The collection efficiency is low. Since only a single finger can be collected, the entire collection process is very time-consuming. Especially for scenes where a large number of fingerprints need to be collected. In order to collect flat fingerprints and rolled fingerprints separately, traditional equipment usually requires bulky brackets and complex settings. This makes them difficult to carry and use in different scenes. Single-finger collection requires law enforcement officers to manually guide the suspect's fingers, which is not only time-consuming, but also prone to errors, affecting the accuracy of fingerprint collection. Since traditional equipment requires law enforcement officers to manually control the collection process, this increases the impact of human factors. Factors such as the proficiency of law enforcement officers and hand stability will affect the quality of fingerprint collection. In the Chinese utility model patent with announcement number CN207123846U and announcement date 2018-03-20, a one-time collection device for face and ten-finger fingerprints is disclosed, which can realize one-time collection of ten-finger fingerprints of both hands, but it is a contact collection, and can only collect flat fingerprints, not rolling fingerprints. In order to solve this problem, a device that can collect flat fingerprints and rolling fingerprints at the same time is needed. Utility Model Content

[0031] like Figures 1 to 3As shown, the utility model provides a ten-finger fingerprint fast non-contact collection device, which includes a collection device body 1 and a fingerprint information collection component. The collection device body 1 is provided with a device inner cavity 2, and the fingerprint information collection component is arranged in the device inner cavity 2. The fingerprint information collection component includes a left-hand multi-finger fingerprint collector and a right-hand multi-finger fingerprint collector. The left-hand multi-finger fingerprint collector and the right-hand multi-finger fingerprint collector both include a collection terminal 7, and cameras are arranged on both sides of the head of the collection terminal 7 for taking pictures of both sides of the fingers.

[0032] When the technical solution of the utility model is used, the user puts the fingers into the left and right multi-finger fingerprint collectors in the inner cavity 2 of the device, and collects the images of the two sides of the fingers through the cameras on both sides of the head of the collection terminal 7, avoiding direct contact, and then synthesizes the plane fingerprint and the rolling fingerprint through the algorithm, which can realize the function of collecting the plane fingerprint and the rolling fingerprint at one time, and can collect the ten fingers of both hands at the same time, which can improve the collection efficiency.

[0033] The device cavity 2 includes a first cavity and a second cavity. The left hand multi-finger fingerprint collector is arranged in the first cavity, and the right hand multi-finger fingerprint collector is arranged in the second cavity. The left and right hand multi-finger fingerprint collectors also include a hand rest 6, which is arranged at the open end of the device cavity 2. The hand rest 6 is provided with a finger positioning groove 601, and each hand rest 6 is provided with a plurality of finger positioning grooves 601. The hand rest 6 is also provided with a thumb positioning column 602. Figure 2 As shown, the device is provided with 10 collection terminals 7, corresponding to 10 finger positioning slots 601, that is, the left and right multi-finger fingerprint collectors are provided with 5 finger positioning slots 601. The thumb positioning column 602 is provided between the thumb positioning slot and the index finger positioning slot to facilitate the user to determine the hand placement position.

[0034] The acquisition terminal 7 is arranged in the extension direction of each finger positioning groove 601. The camera is a high-definition camera 3. In this embodiment, Figure 3 As shown, the upper surface of the head of the acquisition terminal 7 is a concave surface, and two high-definition cameras 3 are installed on the concave surface. Such an installation angle is conducive to taking pictures, and the shooting angle is wider. Specifically, in this embodiment, the cameras of the two high-definition cameras 3 are symmetrically distributed on the perpendicular bisector of the head of the acquisition terminal 7 and the seeker rail 5, and the image of the user's finger is captured by the high-definition camera 3, which can avoid direct contact, avoid cross infection, protect the health of the user, and avoid fingerprint deformation and fingerprint blur caused by fogging. Then, an image processing algorithm is installed to extract the accurate cleaning fingerprint features to ensure that the fingerprint is not deformed.

[0035] The tracking slide 5 is connected between the head of the acquisition terminal 7 and the hand rest 6. The head of the acquisition terminal 7 is slidably connected to the tracking slide 5, and the head of the acquisition terminal 7 can determine the finger position through the image recognition algorithm and automatically slide to the best position point. The tracking slide 5 is rotatably connected to the hand rest 6. When in use, the acquisition terminal 7 is automatically adjusted to the best shooting angle by judging the identified fingerprint texture area.

[0036] The collection terminal 7 also includes a high-brightness light source 4, which is arranged on the upper surface of the head of the collection terminal 7. Figure 3 As shown, a plurality of high brightness light sources 4 are arranged around the upper surface of the head of the collection terminal 7. The camera is a high-definition camera 3. The camera of the high-definition camera 3 can quickly and accurately guide the camera to the correct position to take pictures by identifying the fingerprint orientation.

[0037] When the ten-finger fingerprint fast non-contact collection device is used, the ten-finger fingerprint collection can be completed within 20 seconds, with high collection efficiency. It can collect flat fingerprints and rolling fingerprints at the same time, and has good applicability.
