Human body key point detection method and device of camera

The invention discloses a human body key point detection method and device of a camera, and relates to the technical field of key point detection of embedded equipment. According to the embodiment of the invention, a lightweight backbone network is used to reduce the model size and accelerate model reasoning; the model output size is reduced through up-sampling, and model reasoning is further accelerated; training data are obtained through a web crawler, and the content of a training set is enriched; by quantifying model data, the model performance is optimized under the condition that the model precision loss is reduced as much as possible; the model is coded and compressed, so that more equipment space is saved; the model reasoning operation is accelerated using a neural network processor. According to the human body key point detection method and device for the camera provided by the invention, the computing power of the neural network processor is aroused through the lightweight human body key point detec
