The invention provides a face key point detection method and a face key point detection device. The face key point detection method comprises the following steps: extracting thermodynamic diagram features and coordinate value features based on a face image; and detecting face key points based on the thermodynamic diagram features and the coordinate value features. Compared with an existing face key point detection method, the face key point detection method has the advantages that the thermodynamic diagram features and the coordinate value features extracted on the basis of the face images are used for detecting the face key points at the same time, and then detection precision and real-time performance can be both considered. 提供一种人脸关键点检测方法和人脸关键点检测装置。所述人脸关键点检测方法包括：基于人脸图像提取热力图特征和坐标值特征；基于热力图特征和坐标值特征来检测人脸关键点。根据本发明的人脸关键点检测方法，相比于现有的人脸关键点检测方法，由于同时利用了基于人脸图像提取的热力图特征和坐标值特征来检测人脸关键点，因此，可以兼顾检测精度和实时性。
