Claim 5:
6. An unmanned aerial vehicle, comprising a vehicle body, vehicle arms connected to the vehicle body, power apparatuses disposed on the vehicle arms, an image capturing apparatus connected to the vehicle body and a vision chip disposed in the vehicle body, wherein the vision chip comprises:
a memory and a processor, wherein
the image capturing apparatus is electrically connected to the processor;
the memory is configured to store a zoom program executable on a computer; and
the processor is configured to invoke the zoom program executable on the computer to:
control the image capturing apparatus to capture an initial image, wherein a resolution of the initial image is W0*H0 and an area of the initial image is S0;
obtain a cropped image according to the initial image, wherein the cropped image is an image with an area of S cropped from a preset region in the initial image, S0/S=C and C is a digital zoom factor of the image capturing apparatus; and
obtain a zoom image according to the cropped image, wherein the zoom image is an image obtained by zooming the cropped image by C/A times, a resolution of the zoom image is W1*H1, A=W0/W1, B=H0/H and C≤A;
and storing the zoom image in the memory;
wherein obtaining a cropped image according to the initial image, the method further comprising,
if B>A, cropping X parts to the initial image to obtain the cropped image, and zooming out the cropped images by A times to obtain the zoom image with a width of W1 and a height of H1, X parts is upper and lower regions on two opposite sides of the initial image;
if A>B, cropping Y parts to the initial image to obtain the cropped image, and zooming out the cropped images by B times to obtain the zoom image with a width of W1 and a height of H1, Y parts is left and right regions on two opposite sides of the initial image.
