The Camera Tracker utility’s Error Thresholds rollout attempts to identify feature tracking errors by taking measurements and comparing them to the thresholds that you set up in this rollout. You can use this detection can be used both during a manual tracking review or during actual tracking to correct errors using the Resample On Error control in the Motion Trackers setup rollout.

Match Error

A sum-of-differences-squared measure in RGB space of the best match in the current frame to the feature target from the previous keyframe. The error shown is a percentage of the maximum possible image difference. Good matches are usually below 0.05 percent.Variance Delta

The difference in RGB color variance between the feature target image and the current best match. This measures whether the target and match have similar color ranges and can compensate for mistakes made by the sum-of-differences measure.Jump Delta

The tracker computes a moving average for the preceding five frames and measures the difference between that average and the jump in the current frame. If this difference exceeds the current Jump delta threshold, a potential error is flagged. If the threshold is set to five, any jump in the current frame that’s five pixels more than the average jump in the last five frames is flagged. This picks up sudden accelerations rather than just large jumps.

You can adjust the thresholds as needed and enable or disabled individual measures in the detector using the checkboxes to the left of each measure.

From simple tripod head to complex virtual tracking, the daily use of studio cameras in the radio and television field can not be separated from the cooperation of professional camera support equipment. So today, let's introduce several camera support systems. In this issue, we have selected three categories of products to introduce to you based on our own business characteristics. They are:

1. Virtual Head Tracking

The virtual head tracking system is also one of the camera supporting equipment. It generally works with the virtual production system in the studio production system, and can greatly improve the visual effect of the program in combination with the characteristic scenes.

SEEDER is the first R&D manufacturer of the pan and tilt adopt 23 bit absolute encoder. This is an innovation of our camera tracker, which ensures the tracking resolution of 8,300,000 / 360 °. High precision and real-time tracking greatly improves the quality of the program and work efficiency.

2. Robotic Camera Systems

With the continuous development of technology, the labor intensity and accuracy of program production are also constantly improving. How to improve the shooting equipment, the robotic camera system is a choice.

The anti shake technology, especially no shake when starting and stopping, ensures that every start and stop picture video can be used normally. And the AI 8-axis curvilinear motion ensures the shooting of complex motion video. Thus, the SEEDER robotic camera crane system with these features can bring more and more choices for your program screen effect and shooting scene, and improve your artistic creation space. SEEDER robotic series perfectly suitable for automation studios and can remote photography by just one person with one-click operation. This is very safe, stable, simple and efficient!

3. Camera Support Systems

The camera tripod systems are generally divided into light weight and heavy-duty tripods according to the payload, studio and outdoor use according to the  place, and 100% carbon fiber and aluminum tripods according to the material.

Full CNC (computer numerical control) processing tripod refers to the connector, lock knob, plate and head, which are all CNC processing technology, which is also the distinctive feature of SEEDER's tripods. This is different from plastic or mold metal tripod, it is high precision, high intensity and very durable.
