Abstract: A method for detecting an object utilizing a monocular camera obtains an image showing an object and determining a pixel coordinate of the object in the image and determining a spatial position of the object in the image, based on the pixel coordinate of the object in the image and a preset coordinate transformation relationship or a preset depth prediction model. The image showing the object is obtained through the monocular camera, and the pixel coordinates of the object in the image are determined. According to the pixel coordinates of the object in the image and the preset coordinates transformation relationship or the preset depth prediction model, the spatial position of the object in the image is determined, providing efficient and accurate detection. An electronic device and a non-transitory storage recording the method are also disclosed.
