mAP (Mean Average Precision) is a metric to measure the accuracy of various object detection models. You can measure mAP for different IoU thresholds (eg: 0.5, 0.7 0.9).
Steps to calculate maP:

1. Calculate precision and recall for all the bounding boxes(with different IoU).
2. Use the point interpolation method to plot the graph of recall versus precision.
3. Take the average of all interpolation values to get the Average Precision.
4. Take the mean of all AP with different IoU. The result will be the final mAP.
