Abstract: A method of training an object detection network, an object detection method and related apparatuses are provided. The training method includes: inputting a training image into a to-be-trained object detection network to obtain detection information of a target object, where the detection information includes a detection class of the target object, a detection position of a detection box of the target object, and a detection position of a landmark of the target object; calculating a total loss function of the to-be-trained object detection network, where the total loss function is calculated according to a loss function of the detection class of the target object, a loss function of the detection position of the detection box of the target object, and a loss function of the detection position of the landmark of the target object; and adjusting a parameter of the to-be-trained object detection network according to the total loss function.

Abstract: A distance measurement method is provided. The distance measurement method includes obtaining an image of a target device, the image of the target device including a target object of a first color and a background object of a second color, the first color being different from the second color; processing the image of the target device to obtain a processed image, the processed image including a processed target object of a third color and a processed background object of a fourth color; detecting a contour of the processed target object of the third color; calculating an area encircled by the contour; and calculating a distance between a camera and the target device upon determination of the area encircled by the contour.

Abstract: A computer-implemented method is provided. The computer-implemented method includes inputting a low-resolution image into a generator; and generating a high-resolution image using the generator based on the low-resolution image. Generating the high-resolution image includes processing the low-resolution image through a plurality of super-resolution generating units arranged in series in the generator. A respective output from a respective one of the plurality of super-resolution generating units has a respective increased image resolution as compared to a respective input to the respective one of the plurality of super-resolution generating units.
