It took me quit significant amount of time searching for this. I figure out how to do it. Thought it might be use full for you as well.
Resolution chart is a chart that you need to lay in the field while you are doing the imagery session. Better to put it in the middle of the field where it can be seen in several images.
Here is what we designed for the resolution chart: You need to print it in 1.0*1.2 m if you are usually flying 80 to 150 meters. I also attached the powerpoint format so you can change the size or targeted resolutions as you wish (remember to change the names 📷😉). If you fly higher you need a larger and you fly lower you need a smaller chart.I also added the powerpoint format so you can change it as you wish. The standards of USAF is: The length of each element should be 5 times larger than the width. Three horizontal and three vertical rectangular elements make a group. If you can see the element of a group, the width of the element is the true resolution. In the attached figure, if you only can separate the elements of the largest group, the true resolution of your imagery is 8 cm. If you can see the elements of the smallest group, the true resolution will be 1 cm. Also, horizontal and vertical elements of the groups can show if your horizontal or vertical resolution on the camera in the mission is different or not.

Dear it is easy to use the size of captured object with its real size to get the resolution!
