Autonomous Driving Data
High-sensitivity perception system is the core of autonomous driving vehicles. Our independently developed point cloud annotation platform supports 3D to 2D synchronous annotation. This allows us to develop data with higher accuracy and quality for model training, thus ensuring driving safety.
3D-2D Annotation Platform
2D Annotation
2D annotation includes bounding box, polygon, semantic segmentation and target tracing.

3D Annotation
The 3D annotation plays an important role in improving the accuracy of target and direction detection. Meanwhile, the target detection algorithm can predict the position and attitude of vehicles in real 3D space.

Point Cloud Annotation Platform

The 3D point cloud annotation platform is developed and owned by SurfingTech. It has two versions: Discrete-image Annotation and Video-sequence Annotation.

The discrete image refers to single frame point cloud data with no time sequential connections. Each frame image needs to be annotated separately as shown below. Very often, the number of points in a single frame image is insufficient, thus it is necessary to project the color of the 2D image onto the corresponding point in the 3D point cloud data. At the same time, annotators need to refer to the 2D image to finish the annotation.

For Video-sequence Annotation (scene-based), we reconstruct the 3D scene using to the continuity between frames first and then annotate it in the 3D scene. The annotation is projected back to each frame of 2D images and point cloud data to form the annotation result.

Calibration purpose
- Calculate the Transformation Parameter so that points in one sensor can be transformed into the coordinate system of another sensor - Calculate the correspondence between points in 3D point cloud data and points in 2D image data, which is more helpful for improving the accuracy of scene understanding.

Fine Registration
Introduce more information to optimize the results of Global Registration.
Solution Selection
The final value of the transformed parameter is calculated using a non-maximum suppression method.
Global Registration
Calculate a set of possible Transformation Parameter parameters at a faster rate.
Vehicle Refitting
We provide a line-controlled retrofit solution for Lincoln MKZ Hybrid and Geely Borui GE models. It can provide vertical control (throttle, brake) and lateral control (steering system) capabilities, as well as control of gears and turn signals. At the same time, it can provide necessary body state information feedback, such as vehicle speed, wheel speed, steering wheel angle, throttle opening, GPS, four-door two-cover switch status. The modification cycle takes one day, and the company's wire-controlled modification is a non-destructive modification that does not change the original vehicle's actuator.
