如何调用系统拍照并获取图片

import { cameraPicker } from '@kit.CameraKit';
import { camera } from '@kit.CameraKit';
import { BusinessError } from '@ohos.base';
import { hilog } from '@kit.PerformanceAnalysisKit'


@Entry
@Component
struct ImagePickerPage {
  @State uri: Resource | string | undefined = undefined;
  private cameraPosition: Array<camera.CameraPosition> = [
    camera.CameraPosition.CAMERA_POSITION_UNSPECIFIED, camera.CameraPosition.CAMERA_POSITION_BACK,
    camera.CameraPosition.CAMERA_POSITION_FRONT
  ];
  private mediaType: Array<cameraPicker.PickerMediaType> = [
    cameraPicker.PickerMediaType.PHOTO, cameraPicker.PickerMediaType.VIDEO
  ];

  build() {
    Row() {
      Column() {
        Image(this.uri)
          .width("100%")


        Button("拍照")
          .width("80%")

          .onClick(async () => {
            try {
              let pickerProfile: cameraPicker.PickerProfile = { cameraPosition: this.cameraPosition[1] };

              let pickerResult: cameraPicker.PickerResult = await cameraPicker.pick(getContext(this),
                [this.mediaType[0]], pickerProfile);
              // Get video URI
              this.uri = pickerResult.resultUri;
              hilog.info(0x0000, ' ', "the pick pickerResult is:" + JSON.stringify(pickerResult));
            } catch (error) {
              let err = error as BusinessError;
              hilog.error(0x0000, '', `the pick call failed. error code: ${err.code}`);
            }
          })
      }
      .width("100%")
    }
    .height("100%")
  }
}
