The present application relates to the field of
computer vision, and discloses a low-power long-endurance hunting camera method and
system, comprising: constructing a multi-level sensing layer of the hunting camera, collecting a thermal
signal sequence and a
grayscale contour image of an application scene to extract a multi-dimensional biological
feature vector in the application scene; calculating a matching degree of the multi-dimensional biological
feature vector and a non-target feature; when the matching degree is lower than a preset threshold, generating a first-level wake-up
signal of the hunting camera; collecting a preliminary
infrared image of a potential target, extracting an image feature of the preliminary
infrared image to determine a target prey confidence of the potential target; when the target prey confidence is not higher than a preset
confidence threshold, returning to a low-power sensing layer, and when the target prey confidence is higher than the preset
confidence threshold, generating a second-level wake-up
signal of the hunting camera to switch to a high-resolution sensing layer of the multi-level sensing layer to
shoot a high-definition video of a high-value target. The present application can improve the endurance time and shooting effect of the hunting camera.
