Abstract

A method for determining an angle of a tip of a ripper shank includes a controller receiving an input command. The controller estimates an angle of the tip based on one or more parameters of the input command. Further, the controller acquires a video feed of the ripper shank and detects an object in the video feed. The controller identifies the object as one of the ripper shank or a component movable with a movement of the ripper shank based on a match of a color of the object to a predefined color and a match of a profile of the object to a predefined profile. The controller co-relates the profile to an angular value in a map table and sets the angular value to be an actual angle of the tip over the angle of the tip estimated based on the input command.

Claims (8)

1. A method for determining an angle of a tip of a ripper shank in a dozer machine, the method comprising:

receiving, by a controller, an input command;

estimating, by the controller, the angle of the tip based on one or more parameters of the input command;

acquiring, by the controller, a video feed of the ripper shank captured by one or more image capturing devices in response to the input command;

detecting, by the controller, one or more objects in the video feed;

identifying, by the controller, at least one object of the one or more objects as one of the ripper shank or a component movable with a movement of the ripper shank based on a match of a color of the at least one object to a predefined color and a match of a profile of the at least one object to a predefined profile;

co-relating, by the controller, the profile to an angular value in a map table, the map table including a plurality of angular values corresponding to a plurality of profiles of the at least one object; and

setting, by the controller, the angular value obtained by co-relating the profile in the map table to be an actual angle of the tip over the angle of the tip estimated based on the input command.
