An image collection method, performed by an image collection device, the image collection device comprising a light supplement lamp, a master camera, a slave camera, and a controller, the method comprising:
- transmitting, by the controller, a first exposure control signal to the master camera, wherein a frame synchronization interface of the master camera is connected to a frame synchronization interface of the slave camera, the frame synchronization interface of the master camera is configured to be in an output state, and the frame synchronization interface of the slave camera is configured to be in an input state;
- performing, by the master camera, periodic exposure at an exposure frequency configured by the controller, based on receiving the first exposure control signal;
- transmitting, by the master camera and the frame synchronization interface of the master camera, a frame synchronization signal to the slave camera based on completion of a single exposure;
- performing, by the slave camera, exposure based on receiving the frame synchronization signal by the frame synchronization interface of the slave camera, wherein an exposure time period of the slave camera is staggered from an exposure time period of the master camera;
- controlling, by the controller, the light supplement lamp to periodically supplement light, based on exposure moments of the master camera and the slave camera,
- wherein a light supplement time period of the light supplement lamp covers the exposure time period of the master camera and the exposure time period of the slave camera, the second timer duration being greater than or equal to single exposure durations of the master camera and the slave camera, and a frame duration being an integer multiple of a sum of the first timer duration and the second timer duration;
- and
- transmitting, by the master camera and the slave camera, collected image data to the controller.
