180°翻转摄像头后,热成像图像没有翻转

如图,热成像区域和实际显示的手部区域是镜像是反的
我想把热成像区域翻转一下# MLX90621 Overlay Demo # # This example shows off how to overlay a heatmap onto your OpenMV Cam's # live video output from the main camera. import sensor, image, time, fir ALT_OVERLAY = False # Set to True to allocate a second ir image. sensor.reset() sensor.set_hmirror(True) sensor.set_vflip(True) sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.QQVGA) sensor.skip_frames(time = 2000) # Initialize the thermal sensor fir.init(type=fir.FIR_MLX90621) # Allocate another frame buffer for smoother video. extra_fb = sensor.alloc_extra_fb(sensor.width(), sensor.height(), sensor.RGB565) # FPS clock clock = time.clock() while (True): clock.tick() # Capture an image img = sensor.snapshot() # Capture FIR data # ta: Ambient temperature # ir: Object temperatures (IR array) # to_min: Minimum object temperature # to_max: Maximum object temperature ta, ir, to_min, to_max = fir.read_ir() if not ALT_OVERLAY: # Scale the image and belnd it with the framebuffer fir.draw_ir(img, ir) else: # Create a secondary image and then blend into the frame buffer. extra_fb.clear() fir.draw_ir(extra_fb, ir, alpha=256) img.blend(extra_fb, alpha=128) # Draw ambient, min and max temperatures. #img.draw_string(8, 0, "Ta: %0.2f C" % ta, color = (255, 0, 0), mono_space = False) #img.draw_string(8, 8, "To min: %0.2f C" % to_min, color = (255, 0, 0), mono_space = False) #img.draw_string(8, 16, "To max: %0.2f C"% to_max, color = (255, 0, 0), mono_space = False) # Force high quality streaming... img.compress(quality=90) # Print FPS. print(clock.fps())

我想应该没有这个功能。
