Abstract: A method for detecting an object in an environment of a machine is provided. The method includes determining a first height of the object by applying sliding window detection process on an image. The method determines a score indicating a probability that the object detected in the image matches a predefined set of characteristics. The method further includes determining a minimum and a maximum vertical pixel associated with the object. The method includes determining a second height of the object based on a range of the object, the minimum vertical pixel, the maximum vertical pixel, intrinsic and extrinsic calibration parameters of the image capturing device. The method includes comparing the first height with the second height and accordingly, modifying the score regarding the detection of the object in the image based on whether a difference between the first height and the second height meets a predetermined criterion.

Abstract: A work tool recognition system for a work tool coupled to a machine is provided. The system includes an image capturing assembly configured to capture an image feed of the work tool. A controller is communicably coupled to the image capturing assembly. The controller receives the image feed of the work tool from the image capturing assembly. The controller extracts a plurality of features of the work tool from the image feed. The controller classifies the extracted image and determine a confidence value. The controller estimates a size of the work tool. The controller estimates a position and an orientation of the work tool. The controller determines verification features of the work tool and compares the image feed of the work tool with a predetermined dataset based on the classification. The controller identifies a type of the work tool based on the comparison.
