Application: Object recognition device (Patent ID: US20230418659A1)
The patent filed by Hitachi Ltd. describes an object recognition device that includes a processor and memory to input point cloud sensor data and execute object recognition processing through a software pipeline with multiple stages. The processor has processing units allocated to each stage, and the memory includes task queue regions to temporarily store output data of each stage. If the output data of a stage is invalid for the subsequent stage, the processor rejects the data without storing it in the task queue regions.
The device further includes enqueue determination units to decide whether to store output data in task queue regions, with priority assigned based on the number of unprocessed output data pieces. The processor dynamically allocates processing units to stages based on task queue region priorities. The object recognition processing involves decoding sensor data, grouping coordinate data, performing projective transformation, and clustering index information. Multiple software pipelines can be used for different azimuth angles sensed by the sensor, and each processing unit executes a partial recognition algorithm specific to its stage.
