The present application particularly relates to a lizard scale structure extraction method based on deep learning and geometric topology, aiming to solve the problems of large performance consumption, weak generalization ability and lack of end-to-end automatic process in traditional methods. The DETR architecture is used to automatically locate the foot region from the lizard image, the BiRefNet bidirectional reference network is used to simultaneously reconstruct the lizard scale structure and the foot body, the Douglas-Peucker algorithm is used for multi-scale polygon approximation to initialize the key points, and the iterative smoothing mechanism of local duty cycle classification is introduced to separate the main body and the adhesion impurities, the topological potential field map is constructed by mask difference, the local maximum value is extracted as the seed point, the watershed algorithm is applied to realize the optimal segmentation of the adhesion scale individual, the false detection points are removed through the area stability filtering and secondary clustering, and the geometric feature modeling is carried out. The automatic, high-precision extraction and quantitative analysis of extremely fine biological structures are realized.

The invention provides a non-invasive PCR (Polymerase Chain Reaction) sex identification method for tortoises, and belongs to the technical field of tortoise sex identification. The method comprises the following steps: extracting genome DNA from a non-invasive sample, taking the genome DNA as a template, carrying out PCR amplification by using primers as shown in SEQ ID NO.1-6, and judging that the non-invasive sample is male when an internal reference band of 432 bp and a male specific band of 278 bp appear in an amplification product at the same time; and when an internal reference band of 432 bp and a female specific band of 196 bp simultaneously appear in the amplification product, judging that the amplification product is female. Amplification primers used in the method are designed according to conserved sequences of gender-specific genes of the tortoises, the primers are extremely high in specificity, do not have cross amplification with reptiles such as snakes and lizards, and are adaptive to more than 10 common tortoises such as grass tortoises, brazilian tortoises and land tortoises, the specificity reaches 100%, the accuracy reaches 99% or above, and the method has good popularization and application prospects.

The utility model discloses an intelligent catching device for desert lizards, which relates to the technical field of lizard catching and comprises a catching cage, a blocking door hinged at one end of the catching cage and a water receiving tank mounted in the catching cage, and further comprises a water storage tank which is fixedly mounted on the inner top wall of the catching cage and positioned right above the water receiving tank, and drinking water is stored in the water storage tank; the water outlet pipe is fixedly inserted into the center of the bottom of the water storage tank in the vertical direction, and an electromagnetic valve is arranged on the water outlet pipe; the timer is arranged on the front side of the water storage tank; after a lizard enters the catching cage, the lizard presses the supporting plate to move downwards due to the body weight and abut against the first electromagnetic button, then the first electromagnetic button sends an electric signal to the timer and activates the timer, and then the timer can control the electromagnetic valve to be opened in a timed mode, so that drinking water in the water storage tank is injected into the water receiving tank in a timed mode; it is guaranteed that the captured lizards can continuously drink water, and the problem that drinking water is evaporated in high-temperature weather is avoided.
