A dispersed object collection system comprising an electric machine configured to: run by itself along a set running route in an activity area (Fa), start from a collection place (Ga), run by itself in a set working area to accommodate dispersed objects dispersed in the working area into an accommodation section provided in or outside the machine, and collect the dispersed objects in the collection place (Ga), the dispersed object collection system further comprising: a camera configured to look down at the activity area (Fa) to capture an image of the activity area (Fa) and a work instruction transmitter configured to set the working area in the activity area (Fa) and set a running route through which the machine having started from the collection place (Ga) performs the collection work in the set working area and returns to the collection place (Ga), wherein the work instruction transmitter is further configured to: acquire an image of the field in the activity area (Fa) in which dispersed objects are dispersed, from the camera, recognize the positions of the dispersed objects existing in the acquired image on a position coordinate (X-Y coordinate) corresponding to the capturing range of the acquired image, characterized in that the work instruction transmitter is further configured to form an aggregation region (Se; Se1, Se2) by connecting unit regions, each of the unit regions having the number of dispersed objects equal to or greater than a set value or, alternatively, set the aggregation region (Se; Se1, Se2) such that a distance between two adjacent dispersed objects is equal to or smaller than a set value, and set the working area as a closed region along outer edges of the dispersed objects in the aggregation region in which a plurality of dispersed objects are close together. run by itself along a set running route in an activity area (Fa), start from a collection place (Ga), run by itself in a set working area to accommodate dispersed objects dispersed in the working area into an accommodation section provided in or outside the machine, and collect the dispersed objects in the collection place (Ga), the dispersed object collection system further comprising: a camera configured to look down at the activity area (Fa) to capture an image of the activity area (Fa) and a work instruction transmitter configured to set the working area in the activity area (Fa) and set a running route through which the machine having started from the collection place (Ga) performs the collection work in the set working area and returns to the collection place (Ga), wherein the work instruction transmitter is further configured to: a camera configured to look down at the activity area (Fa) to capture an image of the activity area (Fa) and a work instruction transmitter configured to set the working area in the activity area (Fa) and set a running route through which the machine having started from the collection place (Ga) performs the collection work in the set working area and returns to the collection place (Ga), wherein the work instruction transmitter is further configured to: acquire an image of the field in the activity area (Fa) in which dispersed objects are dispersed, from the camera, recognize the positions of the dispersed objects existing in the acquired image on a position coordinate (X-Y coordinate) corresponding to the capturing range of the acquired image, form an aggregation region (Se; Se1, Se2) by connecting unit regions, each of the unit regions having the number of dispersed objects equal to or greater than a set value or, alternatively, set the aggregation region (Se; Se1, Se2) such that a distance between two adjacent dispersed objects is equal to or smaller than a set value, and set the working area as a closed region along outer edges of the dispersed objects in the aggregation region in which a plurality of dispersed objects are close together.
