Shooting system and shooting method based on human shape detection

The invention discloses a shooting system and a shooting method based on human shape detection. The shooting system comprises a detection sensor, a network component, a main control processor and an image sensor which are connected in sequence, the detection sensor is used for detecting whether a detection signal exists in the current environment or not and generating a corresponding detection result; the network component is used for reading the detection result and sending first information to the main control processor when the detection result is read to be that the detection signal exists; the main control processor is used for receiving the first information, executing a power-on operation based on the first information and sending a first control signal to the image sensor; the image sensor performs shooting based on the first control signal to obtain a shot image, and transmits the shot image to the main control processor; and the main control processor is also used for carrying out human shape detect
