Open ('INPUT.tif') except RuntimeError, e: print Unable to open INPUT.tif print e sys. The problem is I think that this is a very slow process and I want to know if there is a automatic convert-process. from osgeo import gdal import sys this allows GDAL to throw Python Exceptions gdal. Image = cv2.transpose(image) # Rotate by 90 degress (clockwise) Image = cv2.flip(image,0) # flip in Y-axis Image = np.swapaxes(image,2,0) # convert from (height, width, channels) to (channels, height, width) from osgeo import gdal gimage gdal.Open('161104hqtransparentmosaicgroup1.tif') aimage gimage.ReadAsArray() can't test as i don't have enough available memory to open that image. Image = tmp # swap read channel and blue channel You can try and open the image in gdal instead.
#Python gdal open code
I can convert from GDAL format to OpenCV format with the following code image = ds.ReadAsArray() #Load image with GDAL The image loaded by GDAL (after change shape, of course) is (resized to 700x700)įinally, If I try to convert this image from BGR to RGB with image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB) The image loaded by OpenCV is (resized to 700x700):
The image shape expected by OpenCV is (width, height, channels) and GDAL return an image with (channels, width, height) shape.GDAL load images as RGB instead of BGR (used by default in OpenCV).Its size is: 26747, 25388 and 4 bands.Īny help to figure out what is the problem?Įdit: I tried the solution suggested by and it works, the problem is then I need to do some image processing with OpenCV and the image loaded by GDAL has several issues Image in Urban mapping (eBee Plus/senseFly S.O.D.A.) > Map (orthomosaic) doesn't work. In addition, the ability to call GDAL commands from other scripting languages, such as Python, allows for easy iteration through geoprocessing tasks, or integration of geoprocessing steps into complex scripted workflows. Image in Assessing crops with RGB imagery (eBee SQ) > Map (orthomosaic) works well. Why Use GDAL For users processing large amounts of data, or those who prefer to work outside of a GIS environment, GDAL is a logical choice. The problem is for a specific image imread return None. In this program i read GeoTiff image with the following line image = cv2.imread(sys.argv, cv2.IMREAD_LOAD_GDAL | cv2.IMREAD_COLOR)
I have a very simple program in python with OpenCV and GDAL.
