Internet makes large-sample web surveys easy and inexpensive. However, the survey non-response rate (or missing response) is generally high. It is reasonably expected that the survey non-response rate increases as the number of survey questions increases. We propose a partial survey method, in which only a subset of survey questions are distributed to each tester and different testers may receive different questions. Then, the tester can spend much less time responding a short survey compared to the full survey (which includes all survey questions), and therefore it is less likely for a tester to decline the survey and hence increases survey response rate. A mixed survey, composed of the partial survey and full survey, is as well as an extrapolation estimator were also proposed and studied. Simulation was conducted and showed the partial survey produces less biased estimator for the mean response and regression coefficients than the full survey, but with increased standard error for the estimation. The partial survey provides much less mean squared error for the mean response compared to the full survey.

The invention belongs to the technical field of network questionnaire survey, and particularly relates to an anonymous questionnaire survey method based on zero knowledge proof and a block chain. Unbinding of the user identity and the questionnaire filled by the user identity is achieved through zero knowledge proof, an investigation initiator cannot obtain the user information through the submitted questionnaire, and the purpose of hiding the identity information of the investigated user is achieved. And meanwhile, the verification contract deployed on the block chain can ensure that only theuser passing the auditing can submit an effective questionnaire. The processes of questionnaire publishing, questionnaire submitting and the like are deployed on the block chain in a smart contract mode, so that the finally counted questionnaire result is public and credible.

The invention discloses a standard survey method for pests in agriculture and forestry. A transparent nonrigid plastic film with smooth surface is laid on a blue, yellow or red rigid plastic board with grids to form an insect survey board; during field survey of fruit trees or agriculture and forestry plants, plant samples are extracted at random according to the routine technical requirements, the plant samples are surveyed on the east side, the south side, the west side and the north side, a branch is selected in any side, the insect survey boards are placed below the branches of the plant samples, then the branches are hit 3-5 times to enable the pests to fall into the insect survey boards, the grids of the insect survey boards are utilized to count or/and bend the nonrigid plastic films to pour the insects into a collection bottle so as to directly collect live specimens, and the live specimens are used for classification and determination or establishment of experimental population. The standard survey method can be quickly, conveniently and easily operated, overcomes the defect that the data accuracy is influenced by individual result differences caused by manual naked eye observation and different investigators in traditional pest monitoring survey, can be applied to field survey of fruit trees, vegetables and garden plants, and has significance on pest monitoring and pest forecasting and anticipation.

The invention provides a survey apparatus, a survey program and a survey method. A determination unit determines, on images of video data where a road set as a survey target was shot in different times, whether or not the shooting position of the image is within a tolerance value with the shooting position of any of the images as a reference, for each image having a corresponding shooting position.
