In this dataset, we provided the raw analog-to-digital-converter (ADC) data of a 77GHz mmwave radar for the automotive object detection scenario. The overall dataset contains approximately 19800 frames of radar data as well as synchronized camera images and labels. For each radar frame, its raw data has 4 dimension: samples (fast time), chirps (slow time), transmitters, receivers. The experiment radar was assembled from the TI AWR 1843 board, with 2 horizontal transmit antennas and 4 receive antennas. With time-division multiplexing on all transmitters, it can form a 1D-MIMO virtual array with 8 elements.

The data collection was done on the campus, road, and parking lot during the daytime, with the focus of capturing the data for six main objects: pedestrian, cyclist, car, motorbike, bus, truck. The collected objects can be either moving (mostly) or static. A single data collection run consisted of multiple objects listed above moving or being static at a normal speed for 30 seconds in front of the testbed. More information in terms of dataset structure, format, tools, and radar configuration was described below.

The dataset consists of multiple sequences, e.g., "2019_04_09_bms1000", "2019_04_09_cms1000". Under each sequence folder, there exists the image folder "images_0", and radar data folder "radar_raw_frame", and label folder "text_labels".

The overall dataset structure is presented as below.

Automotive
---2019_04_09_bms1000
   ---images_0
   ---radar_raw_frame
   ---text_labels
---2019_04_09_cms1000
   ......

The "radar_raw_frame" folder contains raw ADC radar data in *.mat format, and "images_0" folder contains camera images in *.jpg format, and "text_labels" contains label files for each frame in *.csv format. The detailed data format is explained below.

• For each radar frame, its raw data (*.mat) has 4 dimension:

   samples (128), chirps (255), receivers (4), transmitters (2). 
  

  All transmitters were arranged with time-division multiplexing (TDM), i.e., send chirp signal one by one. The example frame structure is shown as below:

• The placement of 2 transmitters and 4 receivers were plotted in the left figure below, from the TI documentation. Through TDM, the it forms a 1 by 8 MIMO array as shown in the right figure below:

• All radar configurations are included in config.

• The camera image for each frame is with 1440x1080 pixels.

• Each *.csv file include the labels for a frame, with each row of it in format of [uid, class, px, py, wid, len], they are,

   uid: the unique tracking id of objects in this sequence
   class: the class id of objects, with the id number represented in label map, 
   px: x-axis center of bounding box in meters within the range of [-20m, 20m]
   py: y-axis center of bounding box in meters within the range of [1m, 24m]
   wid: width of bounding box in meters (corresponding to x-axis)
   len: lengt of bounding box in meters (corresponding to y-axis)
   
   The mapping of class id to objects is:
   label_map = {0: 'person',
                2: 'car',
                3: 'motorbike',
                5: 'bus',
                7: 'truck',
                80: 'cyclist',
                }
  

Note that There might be few special cases where the px, py values exceed the provided limit and you may just wanna ignore them or do the clipping.
