07 services
01Sonar scan

Sonar Object Detection & Classification

Our sonar data annotation experts identify and classify objects within sonar point returns, accounting for acoustic shadow, target strength, and range-dependent distortion, so the resulting labels reflect what the sensor actually captured rather than an assumed optical equivalent.

02Sonar scan

Sonar Target Detection

Our sonar data annotation experts mark the presence and location of targets across sonar frames using bounding boxes calibrated to sonar resolution, providing the foundation dataset for AI detection models trained on acoustic imagery.

03Sonar scan

Sonar Image Segmentation

Our sonar data annotation experts label objects and seabed boundaries at the pixel or region level within sonar imagery, supporting models that need precise shape and extent data rather than a simple presence or absence label.

04Sonar scan

Sonar Target Classification

Our sonar data annotation experts assign category labels to detected objects, for example distinguishing between debris, marine life, structures, or vessels, based on established classification schema agreed with the client before annotation begins.

05Sonar scan

Sonar Range & Angle Annotation

Our sonar data annotation experts record range and bearing information associated with each detected object.

Discuss this capability
06Object tracks

Underwater Object Tracking

Our sonar data annotation experts track identified targets across consecutive sonar frames or video sequences, maintaining consistent target identity through occlusion, acoustic dropout, and orientation change.

07Terrain contours

Seafloor & Terrain Annotation

Our sonar data annotation experts label seabed features, terrain boundaries, depth variations, and underwater structures.
