1. A surroundings monitoring system for a work machine, the surroundings monitoring system comprising:
a plurality of sensors configured to capture respective images of surroundings of the work machine; and
processing circuitry configured to:
selectively display one of a captured image or an overhead view image at a time on a display, the captured image being an image among the captured respective images of the surroundings of the work machine captured by the plurality of sensors, the overhead view image being an image into which the captured respective images of the surroundings of the work machine captured by the plurality of sensors are combined, the overhead view image viewing the surroundings from above the work machine,
repeatedly detect one or more predetermined monitoring targets in the surroundings of the work machine at predetermined time intervals based on the captured respective images of the surroundings of the work machine captured by the plurality of sensors,
determine whether the captured image or the overhead view image is selectively displayed on the display, and
superimpose a first mark over a first image of the one or more predetermined monitoring targets displayed in the overhead view image in response to detecting the one or more predetermined monitoring targets in a case of determining that the overhead view image is selectively displayed on the display, and superimpose a second mark over a second image of the one or more predetermined monitoring targets displayed in the captured image in response to detecting the one or more predetermined monitoring targets in a case of determining that the captured mage is selectively displayed on the display,
wherein the first mark and the second mark are different in size, and a size of the first mark is smaller than a size of the second mark,
wherein the processing circuitry determines a number of the detected one or more predetermined monitoring targets based on the captured respective images of the surroundings of the work machine,
wherein the processing circuitry selects configuration points representing position information of the first mark or the second mark of the detected one or more predetermined monitoring targets and transmits the position information of the configuration points to the display, and
wherein when the number of the detected one or more predetermined monitoring targets increases, the processing circuitry decreases a number of configuration points of the first mark or the second mark to reduce an amount of data of the position information of the configuration points included in transmission data within a predetermined transmission period with respect to each of the detected one or more predetermined monitoring targets.
