A method and apparatus for measuring the degree of the canopy

Embodiments of the present invention provides a method and apparatus for measuring the degree of the canopy, can solve the high cost of the prior art, the problem of low accuracy. The method comprising: obtaining an image projected crown; converting the image into a gray image; gray image statistics of each gray level pixel; determining the number of pixels of the canopy of each gray level. According to the present invention may be utilized with existing radiography apparatus computing functions, such as smart phones, IPAD, camera + computer, the method of the present invention implanted in the above-described apparatus, can implement the functions of the present invention. Therefore, without additional hardware, access to canopy density by controlling the angle from the image analysis software, easy to operate and implement the resulting findings, high precision, high speed, very suitable for today's forest field investigations.
