PROCÉDÉ DE POSITIONNEMENT DE POINT CLÉ, TERMINAL ET SUPPORT DE STOCKAGE INFORMATIQUE
(ZH)
一种关键点的定位方法及终端、计算机存储介质
Abstract:
(EN)
A key point positioning method, a terminal, and a computer storage medium. The method comprises: upon acquiring a target image, generating, on the target image, according to a pre-set configuration, a target detection region for human facial recognition and positioning; inputting a first target image corresponding to the target detection region into a pre-set first model set, and calculating the position and a first confidence of a first human face key point; when the first confidence is greater than or equal to a pre-set threshold, acquiring a second target image corresponding to the position of the first human face key point in the target detection region; inputting the second target image into the pre-set first model set, calculating a second confidence, and determining the accuracy of the position of the first human face key point according to the second confidence; and when the second confidence is greater than or equal to a pre-set accuracy, determining that the position of the first human face key point is the position of a final human face key point of the target image.
(FR)
Un procédé de positionnement de point clé, un terminal et un support de stockage informatique. Le procédé comprend les étapes suivantes : lors de l'acquisition d'une image cible, générer, sur l'image cible, selon une configuration prédéterminée, d'une région de détection cible pour la reconnaissance et le positionnement du visage humain; à entrer une première image cible correspondant à la région de détection cible dans un premier ensemble de modèles préétabli, et calculer la position et un premier degré de confiance d'un premier point clé de visage humain; lorsque le premier degré de confiance est supérieure ou égale à un seuil préétabli, l'acquisition d'une seconde image cible correspondant à la position du premier point clé de visage humain dans la région de détection cible; l'entrée de la seconde image cible dans le premier ensemble de modèles préétabli, le calcul d'un second degré de confiance, et la détermination de la précision de la position du premier point clé de visage humain selon la seconde confiance; et lorsque le second degré de confiance est supérieure ou égale à une précision prédéterminée, déterminer que la position du premier point clé de visage humain est la position d'un point clé de visage humain final de l'image cible.
(ZH)
一种关键点的定位方法及终端、计算机存储介质。上述方法包括:采集目标图像时,按照预设配置在目标图像上生成用于人脸识别定位的目标检测区域;将目标检测区域对应的第一目标图像输入预设的第一模型集合,计算出第一人脸关键点的位置和第一置信度;当第一置信度大于等于预设阈值时,获取目标检测区域中的第一人脸关键点的位置对应的第二目标图像;将第二目标图像输入预设的第一模型集合,计算出第二置信度,并根据第二置信度判定第一人脸关键点的位置的准确度;当第二置信度大于等于预设准确度时,确定第一人脸关键点的位置为目标图像的最终人脸关键点的位置。
