Control system and control method for controlling work machine in accordance with image data

A system comprising:

• a work machine;
• a camera configured to capture an image including a periphery of the work machine;
• and
• a processor configured to
• acquire image data indicative of a captured image captured by the camera,
• acquire, from the image data, a specific object present in the captured image and a distance from the work machine to the specific object by performing image analysis using an object detection model trained using an image of the specific object and the distance to the specific object,
• control the work machine based on the distance from the work machine to the specific object when the specific object is detected in the captured image,
• acquire the distance for each of a plurality of predetermined time periods, the plurality of time periods including a current time period and a previous time period occurring before the current time period, and
• when a differential between the distance in the current time period and the distance in the previous time period is greater than a predetermined threshold, correct the distance in the current time period so as to reduce the differential.

A method executed by a processor for controlling a work machine, the method comprising:

• acquiring image data indicative of a captured image including a periphery of the work machine;
• acquiring, from the image data, at least one specific object present in the captured image and a distance from the work machine to the at least one specific object by performing image analysis using an object detection model trained using an image of the at least one specific object and the distance to the at least one specific object;
• determining whether the at least one specific object is one specific object or a plurality of specific objects,
• upon determining that the at least one specific object is one specific object, setting the distance from the work machine to the one specific object as a distance parameter and controlling the work machine based on;
• and
• upon determining that the at least one specific object is a plurality of specific objects, selecting a shortest distance among distances from the work machine to the plurality of specific objects as the distance parameter and controlling the work machine based on the distance parameter.
