Top Pickup Computer Vision Models
The models below have been fine-tuned for various pickup detection tasks. You can try out each model in your browser, or test an edge deployment solution (i.e. to an NVIDIA Jetson). You can use the datasets associated with the models below as a starting point for building your own pickup detection model.
At the bottom of this page, we have guides on how to count pickups in images and videos.
How to Count Pickups with Computer Vision
With a model hosted on Roboflow like the ones above and the open source supervision Python package, you can count pickups in your images and videos.
The following code snippet counts the number of pickups present in an image.
To use the snippet below, you will need to run pip install roboflow supervision. Replace the project name and model name with any model trained on Universe, such as those listed above.
import supervision as sv
import roboflow
roboflow.login()
rf = roboflow.Roboflow()
# replace with the pickup project you choose above
project = rf.workspace("pibulsongkarm-rajabhat-university-phtzx").project("motorcycle_traffic_intersection_model-9zgnv")
pickup_model = project.version(66).model
results = pickup_model.predict("pickup.jpg").json()
pickups = sv.Detections.from_roboflow(results)
# print number of pickups
print(len(pickups))How to Count Pickups in a Zone
With a bit more code, you can count the number of pickup present in a specific zone of your image or video.
The following code snippet counts the number of pickup present in each frame in a video.
To use the snippet below, you will need to run pip install roboflow supervision. Replace the project name and model name with any model trained on Universe, such as those listed above.

)How to Track Pickups Crossing a Line
You can count how many pickups have crossed a line using the supervision LineCounter method.
The following code snippet counts the number of pickups that cross a line in a video.
To use the snippet below, you will need to run pip install roboflow supervision. Replace the project name and model name with any model trained on Universe, such as those listed above.
import numpy as np
import supervision as sv
import roboflow

TARGET_VIDEO_PATH = "pickup_out.mp4"
# use https://roboflow.github.io/polygonzone/ to get the points for your line

LINE_END = sv.Point(800, 300)
