5.24. sail.algo_yolov5_post_3output
For post-processing interfaces with a triple output YOLOv5 model, internally implemented using thread pools.
5.24.1. __init__
- Interface:
def __init__( self, shape: list[list[int]], network_w:int = 640, network_h:int = 640, max_queue_size: int=20)
Parameters:
shape: list[list[int]]
The shape of the input data.
network_w: int
The input width of the model, which defaults to 640.
network_h: int
The input height of the model, which defaults to 640.
max_queue_size: int
Maximum length of cached data.
5.24.2. push_data
Support input with arbitrary batchsize.
- Interface:
def push_data(self, channel_idx: list[int], image_idx: list[int], input_data: list[TensorPTRWithName], dete_threshold: list[float], nms_threshold: list[float], ost_w: list[int], ost_h: list[int], padding_attrs: list[list[int]]) -> int
Parameters:
channel_idx: list[int]
The channel number of the input image.
image_idx: list[int]
The sequence number of the input image.
input_data: list[TensorPTRWithName],
The input data, including three outputs.
dete_threshold: list[float]
Detection threshold sequence.
nms_threshold: list[float]
nms threshold.
ost_w: list[int]
The width of original image.
ost_h: list[int]

padding_attrs: list[list[int]]
The attribute list of the fill image, starting point coordinate x, starting point coordinate y, width after scaling, height after scaling.
Returns:
Return 0 if successful, otherwise failed.
5.24.3. get_result_npy
Get the final detection result.
- Interface:
def get_result_npy(self) -> tuple[tuple[int, int, int, int, int, float],int, int]
Returns: tuple[tuple[left, top, right, bottom, class_id, score],channel_idx, image_idx]
left: int
The left x coordinate of the detection result.
top: int

bottom: int
The bottom y coordinate of the detection result.
class_id: int
Category number of detection result.
score: float
Score of detection result.
channel_idx: int
The channel index of original image.
image_idx: int

- Interface:
def reset_anchors(self, anchors_new: list[list[list[int]]]) -> int
Parameters:
anchors_new: list[list[list[int]]]
new anchors.
Returns:
