Problems solved by technology

[0002] The current finger key point detection algorithm can only output the key point coordinates of the finger, and cannot judge whether the finger is incomplete. Therefore, when judging whether the finger is incomplete, the medical staff needs to manually detect it. This not only has a heavy workload for the medical staff, but also improves detection efficiency And the accuracy rate is low, such as there may be missed detection, wrong detection, etc., and there may also be cheating problems

specific Embodiment

[0117] 1) Both hands need to be fully exposed in the screen, and open five fingers, aiming at the specified area in the screen, not exceeding the maximum and minimum areas, otherwise there will be false detection, through the key point detection algorithm (openpose has been open source), The detected finger key points are displayed on the screen as Figure 2A Shown:

[0118] 2) Finger incomplete detection: through the length of symmetrical fingers of left and right hands, the angle of two vectors formed by the adjacent key points of each finger, the ratio of the length of each finger after straightening to the length of the palm, and the length between each finger Ratio, use the Euclidean distance to calculate the ratio of the distance between two key points of each finger, add mathematical logic through the above values, and then judge whether the finger is incomplete.

[0119] 3) Finger function detection: Through the key point detection information after making a fist, use...

Abstract

The invention relates to a finger detection method. The method comprises the following steps: carrying out key point detection on a hand to obtain a plurality of hand key points; determining coordinates of the hand key points; calculating hand detection information according to the coordinates of the hand key points; and according to the hand detection information, detecting whether a residual finger appears on the hand and / or whether the finger of the hand can be bent. By means of the technical scheme, whether the hand has the residual finger or not and / or whether the hand can be bent or notcan be automatically and accurately judged, the workload of physical examination personnel is reduced, the situations of missing detection, wrong detection and the like caused by human factors are avoided, and meanwhile cheating can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of key point detection, in particular to a finger detection method. Background technique [0002] The current finger key point detection algorithm can only output the key point coordinates of the finger, and cannot judge whether the finger is incomplete. Therefore, when judging whether the finger is incomplete, the medical staff needs to manually detect it. This not only has a heavy workload for the medical staff, but also improves detection efficiency And the accuracy rate is low, such as there may be missed detection, wrong detection, etc., and there may also be cheating problems. Contents of the invention [0003] The embodiment of the present invention provides a finger detection method. Described technical scheme is as follows: [0004] According to an embodiment of the present invention, a finger detection method is provided, including: [0005] Perform key point detection on the hand to obtain mu...
