  • typeName: Image type in human-readable format.

  • worldFrame: A 4-by-4 transformation matrix which converts world coordinates to camera coordinates.

  • cameraFrame: A 4-by-4 transformation matrix which converts camera coordinates to world coordinates.

  • distortionFactors: A 1-by-4 matrix with radial distortion factors of 2nd and 4th degrees (k1, k2) and tangential distortion factors (p1, p2).

  • focalLength: The factors are focal length in pixels (fx, fy).

  • principalPoint: principal point (i.e. optical center of the image) in pixels (cx, cy).

  • sensorType: 0 means a matrix camera and 1 means a line camera.

  • imageSize: A 1-by-2 matrix with image width and height in pixels.

  • channelMin: Minimum possible pixel intensity. Notice that this value is not necessarily the true minimum intensity of this particular image. For example, the typical values in an 8-bit grayscale image is min=0 even if all pixel intensities in this image were greater than 0.

  • channelMax: Maximum possible pixel intensity. Notice that this value is not necessarily the true maximum intensity of this particular image. For example, the typical value in an 8-bit grayscale image is max=255 even if all pixel intensities in this image were less than 255.

  • timeStamp: A 32-bit timestamp set by the image source.
