Parameters

Parameter	Type	Required	Description
onnxid	string	Yes	Model ID returned by loadOnnxModel
deviceId	string	Yes	Device ID for getting screenshot

Basic Usage

// 1. Load model
const onnxid = await apiInvoke('loadOnnxModel', {
    file: 'C:\\models\\yolov5s.onnx'
});

// 2. Perform inference
const result = await apiInvoke('predictOnnxModel', {
    onnxid: onnxid,
    deviceId: 'P72578581E07'
});

console.log('Detection results:', result);
